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

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).

I could have sworn that this previously worked for me. Now it installs matplotlib 0.91.1. Not sure what changed, aside from matplotlib releasing a new version. – Matthew Rankin Jan 17 at 15:01 This still installs matplotlib 1.0.0 for me with pip 0.

8.2. Maybe you should check your pip version? If you want the latest version of matplotlib as of now, replace the download url with downloads.sourceforge.Net/project/matplotlib/matplotlib/…. – oyvindio Jan 18 at 9:02 Using pip install -f ... Matplotlib, I end up with version 0.91.1 installed.(I'm using matplotlib.

__version__ to confirm the version installed. I assume it's not reporting 0.91.1 when in fact 1.0.1 was installed. ) I'm running pip 0.8.2 in a environment created with virtualenv 1.5.1.

I'm wondering if distribute 0. 6.14 is causing the problem. Just guessing at this point.

– Matthew Rankin Jan 25 at 17:17 Other problem could be that I was using python2.7 in my virtualenv. I've created a new virtualenv with python2.6 now. I'll post an update with the results.

– Matthew Rankin Jan 25 at 17:29 The problem was the python2.7 virtualenv. With a python2.6 virtualenv, I can use your pip install -f ... Matplotlib and it installs version 1.0.1. The only problem with that is that I get an error when I pip install scipy in the python2.6 virtualenv.

I'm not real found of trading off between scipy and matplotlib, so I'm going to have to investigate a solution for both. – Matthew Rankin Jan 25 at 18:37.

This happens because the download link for matplotlib 1.0 on PyPI points to a URL that doesn't appear to pip to be a file in a known format (the URL ends with /download rather than a filename). See this bug filed on pip. Oyvindio's workaround is the best option I'm aware of for now, until either pip gets more flexible about URLs or matplotlib fixes their PyPI link.

I followed @oyvindio's and @elaichi's advice, but was still getting version 0.91.1, for some unknown reason. This was then failing to compile (with the error src/mplutils. Cpp:17: error: ‘vsprintf’ was not declared in this scope): Installing matplotlib directly from git worked for me: pip install -e [email protected]:matplotlib/matplotlib.

Git#egg=matplotlib.

3 compared to the response that was chosen, this solution will give you the latest code instead of 1.0.0 – meduz May 4 at 11:15.

Oyvindio's advice is great but first I had to install some headers needed to source-compile matplotlib (otherwise it refused to work). In Ubuntu Lucid, it goes like this: $ sudo apt-get build-dep python-matplotlib And just then it was possible to pip install matplotlib: pip install -f URL1 matplotlib.

Thanks for the info. Given you're using apt-get, you must be on a debian derivative. Ubuntu?

Mind updating your answer with your configuration? I just updated my question to state that I'm running on Mac OS X. Thanks.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
