I"ve just updated my Mac OS to 10.9 and I discovered that some (all?) of my Python modules are not here anymore, especially the Image one.
So I try to execute
sudo pip install pil, but I get this error:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/tk.h:78:11: fatal error: "X11/Xlib.h" file not found # include <X11/Xlib.h> ^ 1 error generated. error: command "cc" failed with exit status 1
My Xcode is up-to-date and I don"t have any idea. Is it possible that PIL is not yet 10.9 compatible ?
Following worked for me:
ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Tk.framework/Versions/8.5/Headers/X11 /usr/local/include/X11 sudo pip install pil
But there is more correct solution below, provided by Will.
open your terminal and execute:
