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,  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
              target  interpreter  for  which  to  create  a virtual (either absolute path or identifier 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 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)

       --download
              pass to enable download of the latest pip, setuptools, and wheel from PyPI (default: False)

       --no-download, --never-download
              pass to disable download of the latest pip, setuptools, and wheel from PyPI (default: 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) (default: False)

   activators:
              options for activation scripts

       --activators comma_sep_list
              activators     to      generate      -      default      is      all      supported      (default:

       --prompt prompt
              provides an alternative prompt prefix for this environment (default: None)

       config file $HOME/.config/virtualenv/virtualenv.ini (change via env var VIRTUALENV_CONFIG_FILE)

NOTES

       python2 virtualenvs
              To run pip with python2 requires ipaddr, which is no longer available in the Debian archive (which
              is why it is not included in the package). Additional steps are required:

              [sudo] apt install python3-pip python3-virtualenv
              pip3 install ipaddr
              [sudo] cp $WHEEL_LOCATION/ipaddr-2.2.0-py2.py3-none-any.whl /usr/share/python-wheels/
              [sudo] apt install python2.7

              When ipaddr is installed via pip3, pip3 will list the installation location.  Copy the ipaddr wheel into /usr/share/python-wheels and then create your virtualenv.

              The example uses the python2.7 package from the Debian archive. Eventually that will be removed and users will have to build their own interpreter.
