python pyev 安装

http://pythonhosted.org/pyev/index.html

libev is an event loop: you register interest in certain events (such as a file descriptor being readable or a timeout occurring), and it will manage these event sources and provide your program with events.

pyev — Python libev interface.

所以安装pyev 前先要安装libev, 注意libev的版本

STEP 1]

下载 libev（官网没能进的去。。。），http://download.youkuaiyun.com/detail/lincoln_2012/9718078 ,从优快云下一个

STEP 2]

       下载 pyev，https://pypi.python.org/pypi/pyev/

         

STEP 3]

安装libev

         3-1 解压 tar zxvf  libev-4.15.tar.gz

 3-2  cd libev-4.15;    ./configure;     make;     make install (root 权限)

STEP 4]

       安装 pyev

         4-1 tar zxvf pyev-0.9.0.tar.gz

         4-2  cd pyev-0.9.0;  python setup.py install

报错：

OSError: libev.so.4: cannot open shared object file: No such file or directory

解决：

       vi /etc/ld.so.conf， 添加/usr/local/lib， 再输入ldconfig

     示例：

include ld.so.conf.d/*.conf
/usr/local/lib
      

    再次到pyev解压目录：python setup.py install

Done！
