SYNOPSIS

pex [,-o OUTPUT.PEX/] [,options/] [,-- arg1 arg2 /...]

DESCRIPTION

pex builds a PEX (Python Executable) file based on the given specifications: sources, requirements, their dependencies and other options.

OPTIONS

--version

show program's version number and exit

-h, --help

show this help message and exit

-o PEX_NAME, --output-file=,PEX_NAME/

The name of the generated .pex file: Omiting this will run PEX immediately and not save it to a file.

-r FILE, --requirement=,FILE/

Add requirements from the given requirements file. This option can be used multiple times.

-v

Turn on logging verbosity, may be specified multiple times.

--help-variables

Print out help about the various environment variables used to change the behavior of a running PEX file.

Resolver options:

Tailor how to find, resolve and translate the packages that get put into the PEX environment.

--pypi, --no-pypi, --no-index

Whether to use pypi to resolve dependencies; Default: use pypi

-f PATH/URL, --find-links=,PATH//URL, --repo=,PATH//URL

Additional repository path (directory or URL) to look for requirements.

-i URL, --index=,URL/, --index-url=,URL/

Additional cheeseshop indices to use to satisfy requirements.

--disable-cache

Disable caching in the pex tool entirely.

--cache-dir=,CACHE_DIR/

The local cache directory to use for speeding up requirement lookups. [Default: /sbuildnonexistent/.pex/build]

--cache-ttl=,CACHE_TTL/

The cache TTL to use for inexact requirement specifications.

--wheel, --no-wheel, --no-use-wheel

Whether to allow wheel distributions; Default: allow wheels

--build, --no-build

Whether to allow building of distributions from source; Default: allow builds

PEX output options:

Tailor the behavior of the emitted .pex file if -o is specified.

--zip-safe, --not-zip-safe

Whether or not the sources in the pex file are zip safe. If they are not zip safe, they will be written to disk prior to execution; Default: zip safe.

--always-write-cache

Always write the internally cached distributions to disk prior to invoking the pex source code. This can use less memory in RAM constrained environments. [Default: False]

--ignore-errors

Ignore run-time requirement resolution errors when invoking the pex. [Default: False]

--inherit-path

Inherit the contents of sys.path (including sitepackages) running the pex. [Default: False]

PEX environment options:

Tailor the interpreter and platform targets for the PEX environment.

--python=,PYTHON/

The Python interpreter to use to build the pex. Either specify an explicit path to an interpreter, or specify a binary accessible on $PATH. Default: Use current interpreter.

--python-shebang=,PYTHON_SHEBANG/

The exact shebang (#!...) line to add at the top of the PEX file minus the #!. This overrides the default behavior, which picks an environment python interpreter compatible with the one used to build the PEX file.

--platform=,PLATFORM/

The platform for which to build the PEX. Default: linux-x86_64

--interpreter-cache-dir=,INTERPRETER_CACHE_DIR/

The interpreter cache to use for keeping track of interpreter dependencies for the pex tool. [Default: /sbuild-nonexistent/.pex/interpreters]

PEX entry point options:

Specify what target/module the PEX should invoke if any.

-m MODULE[:SYMBOL], -e MODULE[:SYMBOL], --entry-point=,MODULE[/:SYMBOL]

Set the entry point to module or module:symbol. If just specifying module, pex behaves like python -m, e.g. python -m SimpleHTTPServer. If specifying module:symbol, pex imports that symbol and invokes it as if it were main.

-c SCRIPT_NAME, --script=,SCRIPT_NAME/, --console-script=,SCRIPT_NAME/

Set the entry point as to the script or console_script as defined by a any of the distributions in the pex. For example: "pex -c fab fabric" or "pex -c mturk boto".
