problems installing matplotlib on OS X Lion

Lynn_Oliver · September 4, 2011, 5:06am

After many unsuccessful attempts at getting matplotlib installed on OS X Lion, I ran across this page:
Installing Matplotlib on OS X 10.7 with Homebrew « Random Musings for the Digital Age

Following these instructions got me the closest I have been:

$ brew install python

$ brew install gfortran

$ brew install pkg-config

$ easy_install pip

$ pip install numpy

$ cd $HOME

$ git clone https://github.com/matplotlib/matplotlib.git

$ cd matplotlib

$ python setup.py build

$ python setup.py install

At the moment, I’m trying to get a script that was working on EPD 7.1 to work on Python 2.7.2. I’m using the TkAgg backend.

The first messages I see when running the script are:

objc[68962]: Class TKApplication is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /Library/Frameworks/Tk.framework/Versions/8.6/Tk. One of the two will be used. Which one is undefined.

objc[68962]: Class TKMenu is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /Library/Frameworks/Tk.framework/Versions/8.6/Tk. One of the two will be used. Which one is undefined.

objc[68962]: Class TKContentView is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /Library/Frameworks/Tk.framework/Versions/8.6/Tk. One of the two will be used. Which one is undefined.

objc[68962]: Class TKWindow is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /Library/Frameworks/Tk.framework/Versions/8.6/Tk. One of the two will be used. Which one is undefined.

For both Tk and Tcl, …/Versions/Current points to 8.6.

From there, everything is fine until it executes show(), when I get the following messages:

Exception in Tkinter callback

Traceback (most recent call last):

File “/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py”, line 1410, in call

Can anyone suggest how to resolve this problem?

I had a problem getting with Lion as well. I was able to work around it by:

Bryan, thanks for the response.

I installed macports and the environment settings seem to be correct, but when I try “port help selfupdate” I get:

/opt/local/bin/port: line 4: /usr/bin/tclsh: No such file or directory

/opt/local/bin/port: line 4: exec: /usr/bin/tclsh: cannot execute: No such file or directory

I removed the installation of Tcl 8.6 and reinstalled ActiveTcl 8.5.10, but still get the same warnings.

Matplotlib is now complaining about the missing Tcl8.6:

ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/backends/_tkagg.so, 2): Library not loaded: /Library/Frameworks/Tcl.framework/Versions/8.6/Tcl.

I am assuming that your unsuccessful install via macports was after you had macports working; do you know what version of Tcl was installed?

Macports fails with the same warnings after putting a link to tclsh8.5 in /usr/bin/tchsh.

I still seem to be running in circles.

I don’t know about changing backends, but I do need to use TkAgg.

I finally got it working. The instructions from the original email below are what worked, but first I had to uninstall Tcl8.6 (manually). The first time I tried it I deleted something that I shouldn’t have, and ended up with a mess that I cleaned up by doing a full erase/reinstall of Lion. Then I restored the system from a backup, carefully removed Tcl8.6 manually (the uninstall script is broken), removed most of the remnants of macports, reinstalled a few things that were broken by the reinstall of Lion (XCode, XQuartz, WingIDE, TextWrangler), uninstalled and reinstalled Python 2.7.2, reinstalled Tcl8.5, and rebuilt matplotlib per the instructions.

Hopefully it will go much smoother when I set up the new system in a few days.

Thanks for your help…

Lynn
