如何在Mac OS X Lion上安装Python库'gevent'

问题描述 投票:63回答:10

Python库gevent,版本0.13.6(PyPI上的当前版本)不会在OS X Lion,Python 2.7(以及可能的其他版本)上使用pip install。它在Snow Leopard上运行正常。

如何安装此库?

如果可以使用pip install而不是手动或自定义流程来完成奖励,因为它可以很好地与自动构建一起使用。

这是我的pip install输出:

pip install gevent

不发布整个事情!这太多了! 90%的时间,第一个错误就足够了......

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

这意味着未安装提供event.h标头的库。该库被称为libevent(website)。

通常,像这样的编译错误是构建脚本中的一个缺陷。构建脚本应该给出一个错误消息,表明没有安装libevent,这是一个它没有这样做的错误。

要从MacPorts获得解放,然后手动告诉编译器使用CFLAGS环境变量在运行pip时在哪里找到event.hlibevent

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

您也可以使用自制软件来安装libevent:brew install libevent (来自David Wolever的评论)

我正在使用MacOs High Sierra(10.13.3)首先我做了:brew install libevent

我将我的pip版本升级到pip-18.0。然后尝试再次安装以下: -

pip install gevent

有效。

CFLAGS='-std=c99' pip install gevent

见:Can't install gevent OSX 10.11

在OS X 10.11上,clang使用c11作为默认值,所以只需将其转回c99即可。

过了一会儿,我意识到上面提到的CFLAGS变量的路径在从端口安装libevent时起作用,但不是从brew中安装。以下对我有用(在OSX Mavericks上):

$ 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

这是我发现最简单的方法:

使用自制软件安装libevent

$ brew install libevent

安装兜售

$ pip install gevent

这是我能让它发挥作用的唯一方法。

在寻找在Snow Leopard上安装的帮助时找到了这个答案,发布这个以防其他人以同样的方式来这样做。

我通过macports安装了libevent。

export CFLAGS = -I / opt / local / include export LDFLAGS = -L / opt / local / lib sudo pip install gevent

我通过brew安装了libevent,它也失败了,有什么效果与Stephen做的相似,但指向brew默认安装:

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

如果您从源安装所有并使用csh,以下适用于mac os 10.9

  1. 下载最新稳定的http://libevent.org/ libevent-2.0.21-stable 。/配置 使 sudo make install
  2. virtualenv env
  3. source env / bin / activate.csh
  4. setenv CFLAGS“-I / usr / local / include -L / usr / local / lib”
  5. 点子安装

我使用virtualenv和virtualenv包装器,所以我希望这是自包含的。我得到gevent这样工作:

假设您有虚拟环境设置,那么:

workon {my_virtual_env}

然后下载libevent并针对virtualenv安装它。

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

我假设你已经安装了gcc 5+(我使用brew)

希望这可以帮助。
