Pip install fails on Mac OSX: missing compiler #224

Open tritemio opened 10 years ago

tritemio commented 10 years ago

Under Mac OSX, with Anaconda 1.9.1, the nbdiff installation using:

pip install nbdiff

fails due to missing compiler.

I don't have a compiler installed, does nbdiff really need a compiler?

Full error:

SystemError: Cannot locate working compiler
tarmstrong commented 10 years ago

This suggests that we should remove the python-Levenshtein dependency (which is written in C), but in the mean time you might try:

easy_install python-Levenshtein

... which should install a pre-compiled version of that package. Then try pip install nbdiff again.

Does that work?

Sorry for the delay. Even using easy_install I get the same error message:

SystemError: Cannot locate working compiler
