I tried to install matplotlib on OS X Lion with the pip install command, but I get the following error: 

error: command 'clang' failed with exit status 1

Does anyone have a solution?

  • Have you installed Xcode and its command line tools? However even with this I suspect this is a complex install due to the GUI libraries which can be used and I would use a package manager like macports or homebrew – mmmmmm Oct 04 '13 at 15:11
  • I've installed Xcode but what do you mean with the command line tool ? I use brew as a package manager. – PAC Oct 04 '13 at 16:03
  • Xcode just installs the GUI to run C compilers from the command line you need the extra. If you use brew then install matplotlib via it as it solved the issues you are having – mmmmmm Oct 04 '13 at 16:04
  • brew install matplotlib gives Error: No available formula for matplotlib – PAC Oct 04 '13 at 16:14
  • If that's the question I've got gcc installed on my machine. – PAC Oct 04 '13 at 16:15
  • Macports port just works. I use macports but try to mention all package managers, looks like here they are not equal (this seems to be for python based stuff. For brew and matplotlib see http://stackoverflow.com/questions/12363557/matplotlib-install-failure-on-mac-osx-10-8-mountain-lion and other questions – mmmmmm Oct 04 '13 at 17:45

matplotlib is part of the python 2.7 installed with El Capitan, no need to install it.
