如何在Mac OS X Lion上安装Python库’gevent’

Python库gevent,版本0.13.6(当前版本的PyPI)不会pip安装在OS X Lion,Python 2.7(和其他人。)它在雪豹上运行正常。

如何获得此库安装?

奖励点如果它可以使用pip安装,而不是手动或自定义过程,因为那将使用自动化构建很好地玩。

这里是我pip安装输出:

最佳答案
不要张贴整个事情!这太多了! 90%的时间,第一个错误就够了…

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

这意味着没有安装提供event.h头文件的库。库被称为libevent(website)。

一般来说,这样的编译错误是构建脚本中的缺陷。构建脚本应该提供一个错误消息,libevent未安装,这是一个错误,它没有这样做。

要从MacPorts获取libevent,然后手动告诉编译器CFLAGS环境变量在哪里找到event.h和libevent运行pip。

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

你也可以使用homebrew来安装libevent:brew install libevent
