The PEX packaging toolchain.
Project description
PEX
pex is a library for generating .pex (Python EXecutable) files which are executable Python environments in the spirit of virtualenvs. pex is an expansion upon the ideas outlined in PEP 441 and makes the deployment of Python applications as simple as cp. pex files may even include multiple platform-specific Python distributions, meaning that a single pex file can be portable across Linux and OS X.
pex files can be built using the pex tool. Build systems such as Pants, Buck, and {py}gradle also support building .pex files directly.
Still unsure about what pex does or how it works? Watch this quick lightning talk: WTF is PEX?.
pex is licensed under the Apache2 license.
Installation
To install pex, simply
$ pip install pexYou can also build pex in a git clone using tox:
$ tox -e package
$ cp dist/pex ~/binThis builds a pex binary in dist/pex that can be copied onto your $PATH. The advantage to this approach is that it keeps your Python environment as empty as possible and is more in-line with what pex does philosophically.
Simple Examples
Launch an interpreter with requests, flask and psutil in the environment:
$ pex requests flask 'psutil>2,<3'Or instead freeze your current virtualenv via requirements.txt and execute it anywhere:
$ pex -r <(pip freeze) -o my_virtualenv.pex
$ deactivate
$ ./my_virtualenv.pexRun webserver.py in an environment containing flask as a quick way to experiment:
$ pex flask -- webserver.pyLaunch Sphinx in an ephemeral pex environment using the Sphinx entry point sphinx:main:
$ pex sphinx -e sphinx:main -- --helpBuild a standalone pex binary into pex.pex using the pex console_scripts entry point:
$ pex pex -c pex -o pex.pexYou can also build pex files that use a specific interpreter type:
$ pex pex -c pex --python=pypy -o pypy-pex.pexMost pex options compose well with one another, so the above commands can be mixed and matched. For a full list of options, just type pex --help.
Integrating pex into your workflow
If you use tox (and you should!), a simple way to integrate pex into your workflow is to add a packaging test environment to your tox.ini:
[testenv:package]
deps = pex
commands = pex . -o dist/app.pexThen tox -e package will produce a relocateable copy of your application that you can copy to staging or production environments.
Documentation
More documentation about Pex, building .pex files, and how .pex files work is available at https://pex.readthedocs.io.
Development
Pex uses tox for test and development automation. To run the test suite, just invoke tox:
$ toxIf you don’t have tox, you can generate a pex of tox:
$ pex tox -c tox -o ~/bin/toxTox provides many useful commands and options, explained at https://testrun.org/tox/en/latest/. Below, we provide some of the most commonly used commands used when working on Pex, but the docs are worth acquainting yourself with to better understand how Tox works and how to do more advanced commmands.
To run a specific environment, identify the name of the environment you’d like to invoke by running tox --listenvs-all, then invoke like this:
$ tox -e styleAll of our tox test environments allow passthrough arguments, which can be helpful to run specific tests:
$ tox -e py37-integration -- -k test_reproducible_buildTo run Pex from source, rather than through what is on your PATH, invoke via Python:
$ python -m pexContributing

Release Notes
1.6.11
This release brings a consistency fix to requirement resolution and an isolation fix that scrubs all non-stdlib PYTHONPATH entries by default, only pre-pending or appending them to the sys.path if the corresponding –inherit-path=(prefer|fallback) is used.
1.6.10
This is a hotfix release for the bug detailed in #756 that was introduced by #752 in python 3.7 interpreters.
Guard against modules with a __file__ of None. (#757) Issue #756 PR #757
1.6.9
1.6.8
1.6.7
We now support reproducible builds when creating a pex via pex -o foo.pex, meaning that if you were to run the command again with the same inputs, the two generated pexes would be byte-for-byte identical. To enable reproducible builds when building a pex, use the flags –no-use-system-time –no-compile, which will use a deterministic timestamp and not include .pyc files in the Pex.
In Pex 1.7.0, we will default to reproducible builds.

1.6.5
This release fixes long-broken resolution of abi3 wheels.
Use all compatible versions when calculating tags. (#692) PR #692
1.6.4
This release un-breaks lambdex.
1.6.3
This release changes the behavior of the --interpreter-constraint option. Previously, interpreter constraints were ANDed, which made it impossible to express constraints like ‘>=2.7,<3’ OR ‘>=3.6,<4’; ie: either python 2.7 or else any python 3 release at or above 3.6. Now interpreter constraints are ORed, which is likely a breaking change if you have scripts that pass multiple interpreter constraints. To transition, use the native , AND operator in your constraint expression, as used in the example above.

1.1.2
1.1.1
1.1.0
Add support for .pexrc files for influencing the pex environment. See the notes here. #128.
Bug fix: PEX_PROFILE_FILENAME and PEX_PROFILE_SORT were not respected. #154.
Adds the bdist_pex command to setuptools. #99.
Bug fix: We did not normalize package names in ResolvableSet, so it was possible to depend on sphinx and Sphinx-1.4a0.tar.gz and get two versions build and included into the pex. #147.
Adds a pex-identifying User-Agent. #101.
1.0.3
Bug fix: Accommodate OSX Python python binaries. Previously the OSX python distributions shipped with OSX, XCode and available via https://www.python.org/downloads/ could fail to be detected using the PythonInterpreter class. Fixes #144.
Bug fix: PEX_SCRIPT failed when the script was from a not-zip-safe egg. Original PR #139.
Bug fix: sys.exit called without arguments would cause None to be printed on stderr since pex 1.0.1. #143.
1.0.2
Bug fix: PEX-INFO values were overridden by environment Variables with default values that were not explicitly set in the environment. Fixes #135.
Bug fix: Since 69649c1 we have been unpatching the side-effects of sys.modules after PEX.execute. This takes all modules imported during the PEX lifecycle and sets all their attributes to None. Unfortunately, sys.excepthook, atexit and __del__ may still try to operate using these tainted modules, causing exceptions on interpreter teardown. This reverts just the sys unpatching so that the abovementioned teardown hooks behave more predictably. Fixes #141.
1.0.1
Allow PEXBuilder to optionally copy files into the PEX environment instead of hard-linking them.
Allow PEXBuilder to optionally skip precompilation of .py files into .pyc files.
Bug fix: PEXBuilder did not respect the target interpreter when compiling source to bytecode. Fixes #127.
Bug fix: Fix complex resolutions when using a cache. Fixes: #120.
1.0.0
The 1.0.0 release of pex introduces a few breaking changes: pex -r now takes requirements.txt files instead of requirement specs, pex -s has now been removed since source specs are accepted as arguments, and pex -p has been removed in favor of its alias pex -o.
The pex command line interface now adheres to semver insofar as backwards incompatible CLI changes will invoke a major version change. Any backwards incompatible changes to the PEX environment variable semantics will also result in a major version change. The pex API adheres to semver insofar as backwards incompatible API changes will invoke minor version changes.
For users of the PEX API, it is recommended to add minor version ranges, e.g. pex>=1.0,<1.1. For users of the PEX CLI, major version ranges such as pex>=1,<2 should be sufficient.
BREAKING CHANGE: Removes the -s option in favor of specifying directories directly as arguments to the pex command line.
BREAKING CHANGE: pex -r now takes requirements.txt filenames and not requirement specs. Requirement specs are now passed as arguments to the pex tool. Use -- to escape command line arguments passed to interpreters spawned by pex. Implements #5.
Adds a number of flag aliases to be more compatible with pip command lines: --no-index, -f, --find-links, --index-url, --no-use-wheel. Removes -p in favor of -o exclusively.
Adds --python-shebang option to the pex tool in order to set the #! shebang to an exact path. #53.
Adds support for PEX_PYTHON environment variable which will cause the pex file to reinvoke itself using the interpreter specified, e.g. PEX_PYTHON=python3.4 or PEX_PYTHON=/exact/path/to/interpreter. #27.
Adds support for PEX_PATH environment variable which allows merging of PEX environments at runtime. This can be used to inject plugins or entry_points or modules from one PEX into another without explicitly building them together. #30.
Consolidates documentation of PEX_ environment variables and adds the --help-variables option to the pex client. Partially addresses #13.
Adds helper method to dump a package subdirectory onto disk from within a zipped PEX file. This can be useful for applications that know they’re running within a PEX and would prefer some static assets dumped to disk instead of running as an unzipped PEX file. #12.
Now supports extras for static URLs and installable directories. #65.
Adds -m and --entry-point alias to the existing -e option for entry points in the pex tool to evoke the similarity to python -m.
Adds console script support via -c/--script/--console-script and PEX_SCRIPT. This allows you to reference the named entry point instead of the exact module:name pair. Also supports scripts defined in the scripts section of setup.py. #59.
Adds more debugging information when encountering unresolvable requirements. #79.
Bug fix: PEX_COVERAGE and PEX_PROFILE did not function correctly when SystemExit was raised. Fixes #81.
Bug fix: Fixes caching in the PEX tool since we don’t cache the source distributions of installable directories. #24.
0.9.0
This is the last release before the 1.0.0 development branch is started.
Change the setuptools range to >=2.2,<16 by handling EntryPoint changes as well as being flexible on whether pkg_resources is a package or a module. Fixes #55 and #34.
Adds option groups to the pex tool to make the help output slightly more readable.
Bug fix: Make pip install pex work better by removing extras_requires on the console_script entry point. Fixes #48
New feature: Adds an interpreter cache to the pex tool. If the user does not explicitly disable the wheel feature and attempts to build a pex with wheels but does not have the wheel package installed, pex will download it in order to make the feature work. Implements #47 in order to fix #48

0.8.0
API change: Decouple translation from package iteration. This removes the Obtainer construct entirely, which likely means if you’re using PEX as a library, you will need to change your code if you were doing anything nontrivial. This adds a couple new options to resolve but simplifies the story around how to cache packages. RB #785

0.7.0
Rename twitter.common.python to pex and split out from the twitter/commons repo.
0.6.0
Change the interpretation of -i (and of PyPIFetcher’s pypi_base) to match pip’s -i. This is useful for compatibility with devpi.
0.5.10
Ensures that .egg/.whl distributions on disk have their mtime updated even though we no longer overwrite them. This gives them a new time lease against their ttl.
Without this change, once a distribution aged past the ttl it would never be used again, and builds would re-create the same distributions in tmpdirs over and over again.
0.5.9
Fixes an issue where SourceTranslator would overwrite .egg/.whl distributions already on disk. Instead it should always check to see if a copy already exists and reuse if there.
This ordinarily should not be a problem but the zipimporter caches metadata by filename instead of stat/sha, so if the underlying contents changed a runtime error would be thrown due to seemingly corrupt zip file offsets. RB #684
0.5.8
Adds -i/--index option to the pex tool.
0.5.7
Adds twitter.common.python.pex_bootstrap bootstrap_pex_env function in order to initialize a PEX environment from within a python interpreter. (Patch contributed by @kwlzn)
Adds stdin=,stdout=,stderr= keyword parameters to the PEX.run function. (Patch from @benjy)

Improves python environment isolation by correctly scrubbing namespace packages injected into module __path__ attributes by nspkg pth files. RB #116
Adds twitter.common.python.resolver resolve method that handles transitive dependency resolution better. This means that if the requirement futures==2.1.2 and an unqualified futures>=2 is pulled in transitively, our resolver will correctly resolve futures 2.1.2 instead of reporting a VersionConflict if any version newer than 2.1.2 is available.
