Error when trying to install pylibmc on Mac OSX Lion

Question

I've tried pip and easy_install, but I keep getting the following error: error: command '/usr/bin/llvm-gcc' failed with exit status 1

I'm running OSX Lion and the install runs inside a virtualenv, with Python 2.7.2.

Thanks in advance.

Answer 1

it may caused by the libmemcached is not installed. You should install libevent & memcache & libmemcached first before you are trying install the pylibmc. If you are using homebrew, you can use it to finish the progress of install the dependency of the libmemcached. like this:

brew install libmemcached

Answer 2

First a question: is libmemcached installed? If not, install it and retry. It probably is but just in case....

If pylibmc still doesn't install the problem is probably that libmemcached is not installed in a directory where gcc can discover it (this was a macports symptom in my case), in which case you can store the location in the environment when running pip from the command line:

LIBMEMCACHED=/opt/local pip install pylibmc
