Why does pip install matplotlib version 0.91.1 when PyPi shows version 1.0.0?

Update Oct 15, 2012

PyPi is now showing matplotlib at 1.1.0 so this issue is resolved. Install matplotlib via:

pip install matplotlib

Outdated Information Below

PyPi shows matplotlib 1.0.0. However, when I install matplotlib via pip into a virtualenv, version 0.91.1 is installed.

  • Why the difference in versions?
  • Is there a way to pip install matplotlib 1.0.0?

Research

It appears that matplotlib's DOAP record on PyPi is pointing to the correct version. Below is the DOAP record for reference:

Configuration

  • OS: Mac OS X 10.6.6
  • Python 2.7
  • virtualenv 1.5.1
  • pip 0.8.1

Update 24-Aug-10 7:09 AM

Installing from the PyPi mirror also installs version 0.91.1:

$ pip install -i http://d.pypi.python.org/simple matplotlib

Even though matplotlib 1.0.1 has been release, this issue still persists.

Solution

  • I've experienced the same problem. I have no idea why it happens, but I do have a fix; use the -f option in pip to tell it where to find the matplotlib sources. (This works in requirements.txt as well).

    pip install -f http://downloads.sourceforge.net/project/matplotlib/matplotlib/matplotlib-1.0/matplotlib-1.0.0.tar.gz matplotlib
