Error when install pylibmc using pip

问题

Hello when I attempt to install pylibmc on OSX Lion using pip I get the following error:

./_pylibmcmodule.h:42:10: fatal error: 'libmemcached/memcached.h' file not found

#include <libmemcached/memcached.h>

         ^

1 error generated.

error: command 'clang' failed with exit status 1

Any clues at how to solve this issue?

回答1:

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.

回答2:

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"

LIBMEMCACHED=/opt/local pip install pylibmc

as explained in the pylibmc docs.

回答3:

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

回答4:

I have the same problem because i have installed MEMCACHED and not LIBMEMCACHED, so, to resolve:

brew uninstall memcached #to remove wrong package

brew install libmemcached #install correct lib

pip install pylibmc

Its Works for me!

For those finding this answer on Fedora:

sudo yum install libmemcached-devel

i fixed this by installing memcached from port

you should install first macports from http://www.macports.org/

then run this command

sudo port install memcached

after that download the pylibmc from the pypi http://pypi.python.org/pypi/pylibmc extract .tar.gz file then

python setup.py install --with-libmemcached=/opt/local

回答7:

this code is worked for me

  sudo apt-get install libmemcached-dev zlib1g-dev

  LIBMEMCACHED=/opt/local pip install pylibmc

回答8:

Hit the same error with macOS High Sierra, Python3.6 installed with brew. Solution for me was to export these flags, mentioned in this comment: Error when install pylibmc using pip

export LDFLAGS="-L/usr/local/lib"
export CPPFLAGS="-I/usr/local/include"

After that, pip install run just fine.

回答9:

Sometimes the X-Code Command Line Tools need to be installed.

 xcode-select -p
