How can I install the Python library 'gevent' on Mac OS X Lion

Question

Python library gevent, version 0.13.6 (the current version on PyPI) will not pip install on OS X Lion, Python 2.7 (and probably others.) It works f

Answer 1

After a while, I realized that the paths for the CFLAGS variable mentioned above works when installing libevent from port, but not from brew. The following worked for me (on OSX Mavericks):

$ brew install libevent
$ export CFLAGS="-I /usr/local/Cellar/libevent/2.0.21/include -L /usr/local/Cellar/libevent/2.0.21/lib"
$ pip install gevent

Answer 2

This is the way I found the easiest:

install libevent using homebrew

$ brew install libevent

install gevent

$ pip install gevent

This was the only way I could get it to work.

Answer 3

sudo pip install cython git+git://github.com/gevent/gevent.git#egg=gevent

Answer 4

I had libevent installed via brew and it failed too, what worked was similar to what Stephen done, but pointing to brew default install:

CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib pip install gevent

Answer 5

I use virtualenv and virtualenv wrapper, and so I wanted this to be self contained. I got gevent working like so:

Assuming you have virtual env setup, then:

workon {my_virtual_env}

Then download libevent and install it against the virtualenv.

curl -L -O https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz

tar -xzf libevent-2.0.21-stable.tar.gz
cd libevent-2.0.21-stable
./configure --prefix="$VIRTUAL_ENV"
make && make install

I'm assuming you've got gcc 5+ installed (I use brew)

Hope this helps.

I am using MacOs High Sierra (10.13.3) First I did : brew install libevent

I upgraded my pip version to pip-18.0. then tried installing again with following :-

pip install gevent

it worked.
