DESCRIPTION
The virtualenv utility creates virtual Python instances, each invokable with its own
Python executable. Each instance can have different sets of modules, installable via
easy_install. Virtual Python instances can also be created without root access.
optional arguments:
--version
display the version of the virtualenv package and it's location, then exit
--with-traceback
on failure also display the stacktrace internals of virtualenv (default: False)
--app-data APP_DATA
a data folder used as cache by the virtualenv (default: <temp folder>)
--clear-app-data
start with empty app data folder (default: False)
-h, --help
show this help message and exit
verbosity:
verbosity = verbose - quiet, default INFO, mapping => CRITICAL=0, ERROR=1, WARN-
ING=2, INFO=3, DEBUG=4, NOTSET=5
-v, --verbose
increase verbosity (default: 2)
-q, --quiet
decrease verbosity (default: 0)
discovery:
discover and provide a target interpreter
--discovery {builtin}
interpreter discovery method (default: builtin)
-p py, --python py
target interpreter for which to create a virtual (either absolute path or identi-
fier string) (default: /usr/bin/python3)
creator:
options for creator builtin
--creator {builtin,cpython3-posix,venv}
create environment via (builtin = cpython3-posix) (default: builtin)
dest directory to create virtualenv at
--clear
remove the destination directory if exist before starting (will overwrite files
otherwise) (default: False)
--system-site-packages
give the virtual environment access to the system site-packages dir (default:
False)
--symlinks
try to use symlinks rather than copies, when symlinks are not the default for the

--copies, --always-copy
try to use copies rather than symlinks, even when symlinks are the default for the
platform (default: False)
seeder:
options for seeder app-data
--seeder {app-data,pip}
seed packages install method (default: app-data)
--no-seed, --without-pip
do not install seed packages (default: False)
--download
pass to enable download of the latest pip, setuptools, and wheel from PyPI (de-
fault: False)
--no-download, --never-download
pass to disable download of the latest pip, setuptools, and wheel from PyPI (de-
fault: True)
--extra-search-dir d [d ...]
a path containing wheels the seeder may also use beside bundled (can be set 1+
times) (default: [])
--pip version
pip version to install, bundle for bundled (default: latest)
--setuptools version
setuptools version to install, bundle for bundled (default: latest)
--wheel version
wheel version to install, bundle for bundled (default: latest)
--no-pip
do not install pip (default: False)
--no-setuptools
do not install setuptools (default: False)
--no-wheel
do not install wheel (default: False)
--symlink-app-data
symlink the python packages from the app-data folder (requires seed pip>=19.3) (de-
fault: False)
activators:
options for activation scripts
--activators comma_sep_list
activators to generate - default is all supported (default: bash,cshell,fish,power-
