I am migrating my dev environment to 10.8, however I am having issues with pip.
Specifically, I’m using a virtualenvs/virtualwrapper but cannot pip install psycopg2, and during the building of the psycopg2._psycopg extension, I get:
unable to execute /usr/bin/clang: No such file or directory
error: command '/usr/bin/clang' failed with exit status 1
Can anyone offer a solution to this?
This probably happens because you did not re-install the Command Line Tools after upgrading.
Usually XCode should be upgraded to the latest version (4.4) (I believe when I updated to 10.8 I also updated a whole bunch of other applications, including XCode). After the update you need to re-install the Command Line Tools. This can now be done via a setting in XCode:
Go to “Preferences -> Downloads” and install “Command Line Tools”.
Now you should have no more problems when installing packages that need to be compiled.
