We advise installing virtualenv-1.9 or greater. Prior to version 1.9, the pip included in virtualenv did not download from PyPI over SSL.
When using pip to install virtualenv, we advise using pip 1.3 or greater. Prior to version 1.3, pip did not download from PyPI over SSL.
We advise against using easy_install to install virtualenv when using setuptools < 0.9.7, because easy_install didn’t download from PyPI over SSL and was broken in some subtle ways.
To install globally with pip (if you have pip 1.3 or greater installed globally):
$ [sudo] pip install virtualenv
Or to get the latest unreleased dev version:
$ [sudo] pip install https://github.com/pypa/virtualenv/tarball/master
To install version X.X globally from source:
$ curl -LO https://pypi.org/packages/source/v/virtualenv/virtualenv-X.X.tar.gz $ tar xvfz virtualenv-X.X.tar.gz $ cd virtualenv-X.X $ [sudo] python setup.py install
To use locally from source:
$ curl -LO https://pypi.org/packages/source/v/virtualenv/virtualenv-X.X.tar.gz $ tar xvfz virtualenv-X.X.tar.gz $ cd virtualenv-X.X $ python virtualenv.py myVE
virtualenv.py script is not supported if run without the
necessary pip/setuptools/virtualenv distributions available locally. All
of the installation methods above include a
virtualenv.py which contains a complete set of
pip and setuptools distributions, and so are fully supported.
