导读：我正在尝试现代化一点,但无论出于何种原因,pip无法安装任何带有C扩展名的东西.讨厌的罪犯是 MySQLdb,PIL,Fabric.我可以用exe安装它们,但现代需求技术不起作用. 例如,这是PIL的作用(虚拟测试是环境,还没有其他内容)： (virtualtesting) C:UsersjgoldsteinL

我正在尝试现代化一点,但无论出于何种原因,pip无法安装任何带有C扩展名的东西.讨厌的罪犯是 MySQLdb,PIL,Fabric.我可以用exe安装它们,但现代需求技术不起作用.

例如,这是PIL的作用(虚拟测试是环境,还没有其他内容)：

它是Python 2.7(32位),VirtualEnv 1.7,Windows 7(64位).我……干嘛

所以第一个问题：这可以解决吗？

第二个问题：似乎我将exe安装程序运行到主站点包并将结果复制到VirtualEnv的目录中,它可以正常工作.如果我想要一个pip requirements.txt做事模型,这样做有多糟糕呢？

(显然,在服务器上所有这些东西都很好用.)

解决方法

对于第一个问题,请看：
error: Unable to find vcvarsall.bat

无法回答第二个,我不知道：|
