Python – ImportError: No module named memcache

While trying to connect memcached using python I got following error:

ImportError: No module named memcache

Since I imported memcache & it’s not available in my server I got the error message saying that “No module named memcache”.

To resolve this issue we need to install python-memcache module.

Use following command to install python-memcache:

$ pip install python-memcache

If  your OS is Ubuntu/Debian following command also works for you:

$ apt-get install python-memcache

After installing python-memcache we can seamlessly connect to memcached.
