virtualenv - Online in the Cloud

PROGRAM:

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.

OPTIONS

-h, --help
Show summary of options.

--version
Show the version of the program.

-v, --verbose
Be more verbose.

-q, --quiet
Be less verbose; suppress unimportant output.

--clear
Clear out a previously-created virtual Python instance in this location before
creating a new one.

-p PYTHON_EXE,--python=PYTHON_EXE
The Python interpreter to use to create the new environment.

--no-site-packages
Ignored (the default). Don´t give access to the global site-packages modules to the
virtual environment.

--system-site-packages
Give access to the global site-packages modules to the virtual environment.

--always-copy
Always copy files rather than symlinking.

--unzip-setuptools
Unzip Setuptools when installing it. This fixes up scripts and makes all .pth files
relative.

--relocatable
Make an EXISTING virtualenv environment relocatable.

--no-setuptools
Do not install setuptools (or pip) in the new virtualenv.

--no-pip
Do not install pip in the new virtualenv.

--extra-search-dir=SEARCH_DIRS
Directory to search for setuptools/distribute/pip distributions in. Can be specified
multiple times.

--prompt==PROMPT
Provides an alternative prompt prefix for this environment.
