dest
options:
--version display the version of the virtualenv package and its location, then
exit
--with-traceback on failure also display the stacktrace internals of virtualenv
(default: False)
--read-only-app-data use app data folder in read-only mode (write operations will fail
with error) (default: False)
--app-data APP_DATA a data folder used as cache by the virtualenv (default:
/tmp/.cache/virtualenv)
--reset-app-data start with empty app data folder (default: False)
--upgrade-embed-wheels trigger a manual update of the embedded wheels (default: False)
-h, --help show this help message and exit
verbosity:
verbosity = verbose - quiet, default INFO, mapping => CRITICAL=0, ERROR=1, WARNING=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 interpreter based on what to create environment
(path/identifier/version-specifier) - by default use the interpreter
where the tool is installed - first found wins. Version specifiers
(e.g., >=3.12, ~=3.11.0, ==3.10) are also supported (default: [])
--try-first-with py_exe try first these interpreters before starting the discovery (default:
[])
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)
--no-vcs-ignore don't create VCS ignore directive in the destination directory
(default: False)
--venv-redirect point a PEP-832 .venv redirect file next to the destination at the
created environment, even outside a project folder; unset,
virtualenv does so only beside a pyproject.toml with no .venv yet
(default: None)
--no-venv-redirect write no PEP-832 .venv redirect file (default: None)
--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 platform (default: True)
--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)
--no-download, --never-download
pass to disable download of the latest pip/setuptools/wheel from
PyPI (default: True)
--download pass to enable download of the latest pip/setuptools/wheel from PyPI
(default: False)
--extra-search-dir d [d ...] a path containing wheels to extend the internal wheel list (can be
set 1+ times) (default: [])
--pip version version of pip to install as seed: embed, bundle, none or exact
version (default: bundle)
--setuptools version version of setuptools to install as seed: embed, bundle, none or
exact version (default: none)
--no-pip do not install pip (default: False)
--no-setuptools do not install setuptools (default: False)
--no-periodic-update disable the periodic (once every 14 days) update of the embedded
wheels (default: False)
--symlink-app-data symlink the python packages from the app-data folder (requires seed
pip>=19.3) (default: False)
activators:
options for activation scripts
--activators comma_sep_list activators to generate - default is all supported (default:
bash,cshell,fish,nushell,powershell,python,xonsh)
--prompt prompt provides an alternative prompt prefix for this environment (value of
. means name of the current working directory) (default: None)
config file /tmp/.config/virtualenv/virtualenv.ini missing (change via env var
VIRTUALENV_CONFIG_FILE)
