如何在Mac OS X Lion上安装Python库'gevent' [英] How can I install the Python library 'gevent' on Mac OS X Lion

问题描述

Python库gevent，版本0.13.6(PyPI的当前版本)在OS X Lion，Python 2.7(可能还有其他版本)上不是pip install.在Snow Leopard上运行良好.

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 fine on Snow Leopard.

如何安装该库?

如果可以使用pip install而不是手动或自定义过程来完成，则奖励，因为这样可以在自动构建中很好地发挥作用.

Bonus points if it can be done using pip install, rather than a manual or custom process, because then it will play nicely with automated builds.

这是我的pip install输出:

推荐答案

不要发布整个内容！这太多了！ 90％的时间，第一个错误就足够了...

Don't post the entire thing! That's too much! 90% of the time, the first error is enough...

gevent/libevent.h:9:19: error: event.h: No such file or directory

这意味着未安装提供event.h头的库.该库称为libevent(网站).

This means that the library which provides the event.h header is not installed. The library is called libevent (website).

通常，诸如此类的编译错误是构建脚本中的缺陷.生成脚本应显示一条错误消息，表明未安装libevent，这是一个错误，未安装libevent.

In general, compilation errors like these are a flaw in the build scripts. The build script should give an error message that libevent is not installed, and it is a bug that it did not do so.

要从MacPorts获取libevent，然后在运行pip时手动告诉具有CFLAGS环境变量的编译器在哪里可以找到event.h和libevent.

To get libevent from MacPorts and then manually tell compiler with CFLAGS environment variable where to find event.h and libevent while running pip.

sudo port install libevent
CFLAGS="-I /opt/local/include -L /opt/local/lib" pip install gevent

您还可以使用自制软件安装libevent:brew install libevent
(摘自David Wolever的评论)

You can also use homebrew for installing libevent : brew install libevent
