I tried doing this, sudo port install libevent CFLAGS="-I /opt/local/include -L /opt/local/lib" pip install gevent
我尝试这样做， sudo port install libevent CFLAGS="-I /opt/local/include -L /opt/local/lib" pip install gevent
It says port command not found.

I had the same problem and just as the other answer suggested I had to install "libevent". It's apparently not called "libevent-devel" anymore (apt-get couldn't find it) but doing:
我遇到了同样的问题，正如其他答案所建议的那样，我必须安装“libevent”。它显然不再被称为“libevent-devel”（apt-get 找不到），而是执行以下操作：
$ apt-cache search libevent
listed a bunch of available packages.
列出了一堆可用的包。
$ apt-get install libevent-dev
worked for me.
为我工作。

I think you just forget to install the "libevent" in the environment. If you are on a OSX machine, please try to install brew here http://mxcl.github.io/homebrew/and use brew install libevent to install the dependency. If you are on an ubuntu machine, you can try apt-get to install the corresponding library.
我认为您只是忘记在环境中安装“libevent”。如果您使用的是 OSX 机器，请尝试在http://mxcl.github.io/homebrew/上安装 brew，并使用 brew install libevent 安装依赖项。如果你在ubuntu机器上，可以试试apt-get安装对应的库。

I ran into this error on MacOS 10.10.1 (Yosemite) running pip install. The solution for me was to add the path to libevent which pip was missing. These are C files, and CFLAGS and DFLAGS are bash environment variables that let pip know where to find these files. On my system, libevent is found at /usr/local/include/event2.
我在运行 pip install 的 MacOS 10.10.1 (Yosemite) 上遇到了这个错误。我的解决方案是添加缺少 pip 的 libevent 路径。这些是 C 文件，CFLAGS 和 DFLAGS 是 bash 环境变量，让 pip 知道在哪里可以找到这些文件。在我的系统上，libevent 位于 /usr/local/include/event2。
$ CFLAGS=-I/usr/local/include/event2 DFLAGS=-L/usr/local/lib pip install -r requires.txt
