Out of date
The repos have both python-virtualenv and python2-virtualenv, the article is not clear about the differences between Python 2 and Python 3 support. -- Kynikos 09:04, 27 November 2011 (EST)
running 'pip install' from virtualenv will not work if base-devel is not present
When running below procedure:
pacman python-virtualenv cd /home mkdir myvenv virtualenv --always-copy myvenv cd myvenv source bin/activate pip install numpy
I was getting following error:
RuntimeError: Broken toolchain: cannot link a simple C program
It seems gcc was missing from the system. After installing base-devel all works fine.
