VIRTUALENV(1) | VIRTUALENV(1) |
NAME¶
virtualenv - create virtual Python instances
SYNOPSIS¶
virtualenv [options...] [destination-directory]
DESCRIPTION¶
virtualenv creates virtual Python executables, each of which can have its own set of installed modules. Programs that require different versions of modules or sets of modules that may be incompatible with others to be installed on the same system without conflicts.
The result is a directory containing its own Python executables (in DIR/bin/pythonVER and DIR/bin/python) and its own module directory containing the standard library as installed by the system. Additional modules may be installed via setuptools, as invoked from the binary directory (DIR/bin/easy_install). The system´s site-packages directories will not be available by default, but can be made visible with the --system-site-packages option. They can then be overridden with locally-installed modules.
In addition, a shell script called "activate" will be installed in the bin directory. If sourced, this will cause normal invocations of the Python executable to use the virtual environment.
By running the virtualenv command explicitly under the desired Python interpreter, the user can control which version of Python is created in the virtual environment.
