pip install matplotlib fails on mavericks with homebrew
homebrew, matplotlib, osx-mavericks, pip, python
Solution
This is an issue in pygtk. You can test it with brew (it should throw the same error):
brew test pygtk
I ran into the same problem, and got past that error with the following steps from https://github.com/mxcl/homebrew/issues/13654
- `brew rm py2cairo`
- `brew install py2cairo`
You can test that pygtk is working using `brew test pygtk` again.
I'm still having other problems getting `pip install matplotlib` to work, so you may also run into more problems, but that should get you past that particular issue.
Problem
I am trying to install the Scipy python stack, but having issues. I have a new mac os with mavericks (10.9). I have installed homebrew and am using brew to manage installations. I used ``` % brew install python ``` then (I verified pip is from my homebrew installation) ``` % pip install numpy [this works] % pip install scipy [this works] % pip install matplotlib OR pip install http://downloads.sourceforge.net/project/matplotlib/matplotlib/matplotlib-1.3.1/matplotlib-1.3.1.tar.gz ``` Both fail with the same error. After checking the backend, I get ``` Fatal Python error: PyThreadState_Get: no current thread ``` The error message from mac os X (the pop up error window) shows errors very similar to those in the previous thread Homebrew + Python on mac os x 10.8: Fatal Python error: PyThreadState_Get: no current thread importing mapnik It seems I need to fix the python bindings, as some of them linked against the `/System/Library` python that ships with the mac. What is not clear to me from the above post is which of the Binary Images need to be "re-linked"? all of them? some seem quite general an not related to `matplotlib` how do I actually use `install_name_tool` to fix the link? As I mentioned, some seem quite general - do I really want to change the path? Do I `cp` the `dylib` from old to new? I have also tried ``` brew uninstall python ``` and re-brewing, all to get the same error. I am trying not to use `EPD` because `EPD` installs its own `libxml2` and others, which I need for other software I will install, and this has caused me problems on an old machine. I am open to considering a `virtualenv`, but was hoping to learn to just fix my current problem if possible. Thanks, Andre PS, when `pip install` matplotlib`, the following warning appears, which seems odd because matplotlib is such a staple piece of software You are installing an externally hosted file. Future versions of pip will default to disallowing externally hosted files. You are installing a potentially insecure and unverifiable file. Future versions of pip will default to disallowing insecure files.
