first you need to install 

brew install libmemcached

than install python package by this command 

pip install pylibmc --install-option="--with-libmemcached=/usr/local/Cellar/libmemcached/1.0.18/"

  • Thank you so much. I could successfully install pylibmc. – naohide_a Jan 13 '16 at 11:27
  • I used `/usr/local/Cellar/libmemcached` (without specifying the version) and it worked too. – reubano Aug 10 '17 at 15:06
  • Thank you very much for this answer. – hygull Feb 04 '19 at 13:42
  • Depending on the Homebrew version / setup `libmemcached` may be elsewhere, checkout it's location after installing with `brew info libmemcached` and change the install option accordingly. Mine was in `/opt/homebrew/Cellar/libmemcached`. – José Jan 09 '23 at 23:18

Install dev package:

sudo apt-get install libmemcached-dev
sudo apt-get install zlib1g-dev

then install with pip the python package :

pip install pylibmc

Check documentation for requirements

  • Check this @naohide. –  Jan 13 '16 at 11:32
  • I use this in my centos server `yum install libmemcached-devel` and then pylibmc was successfully installed. Hopes this will be helpful for others who got the same issue – Alfred Dec 30 '16 at 01:39

three steps including automatically start memcached server when restarting computers

  1. brew install libmemcached
  2. pip install pylibmc
  3. ln -s /usr/local/Cellar/memcached/1.4.24/homebrew.mxcl.memcached.plist ~/Library/LaunchAgents/ (note: you need to modify the version no to your own one, here is 1.4.24)
  4. launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.memcached.plist (note: if you do not want auto-start memacached server later, you can use unload command)

Update to @Atul's accepted answer above -- first you need to install

brew install libmemcached

then check version installed with

ls /usr/local/Cellar/libmemcached (As of today 1.0.18_2 is the latest)

Now install python package by substituting above version in this command

pip install pylibmc --install-option="--with libmemcached=/usr/local/Cellar/libmemcached/<version>"

e.g.

pip install pylibmc --install-option="--with libmemcached=/usr/local/Cellar/libmemcached/1.0.18_2/"
