How to specify install order for python pip?

Question

I\'m working with fabric(0.9.4)+pip(0.8.2) and I need to install some python modules for multiple servers. All servers have old version of setuptools (0.6c8) which needs to

Answer 1

I ended up running pip inside virtualenv instead of using "pip -E" because with -E pip could still see servers site-packages and that obviously messed up some of the installs.

I also had trouble with servers without virtualenvs. Even if I installed setuptools with separate pip command pymongo would refuse to be installed.

I resolved this by installing setuptools separately with easy_install as this seems to be problem between pip and setuptools.

snippets from fabfile.py:

env.activate = "source %s/bin/activate" % virtualenv_path

_virtualenv("easy_install -U setuptools")
_virtualenv("pip install -r requirements.txt")

def _virtualenv(command)
    if env.virtualenv:
        sudo(env.activate + "&&" + command)
    else:
        sudo(command)

I had these problems with pip 0.8.3 and 0.8.2.
