Error when install pylibmc using pip

libmemcached may also be installed using Homebrew.

brew install libmemcached

After that, pip install pylibmc worked for me without needing to specify any additional arguments.

It's in the libmemcached package. To install it using macports:

sudo port install libmemcached

Then, assuming you're using pip:

pip install pylibmc --install-option="--with-libmemcached=/opt/local"

or

LIBMEMCACHED=/opt/local pip install pylibmc

as explained in the pylibmc docs.

I solved this issue by checking where memcached is installed

$ which memcached
/usr/local/bin/memcached

and then setting LIBMEMCACHED environment variable before pip install:

$ export LIBMEMCACHED=/usr/local
$ pip install pylibmc
