所以我在我的Windows 7笔记本电脑上安装了Python 2.7和setuptools。我还安装了Visual Studio 2008 Express和MysqL与开发工具。
我试图通过pip安装MysqL-python：
pip install MysqL-python

任何想法如何解决这个问题？谢谢
检查两者是32位还是64位，并且它们之间没有不匹配。当我遇到这个问题的时候，是因为我安装了一个64位的Python，但是安装了一个32位的MysqL。因此，pip安装程序可能无法找到要链接到的匹配二进制文件，并且此消息失败。解决这个问题只是一个将顶级的32位Python安装在一起的问题，一切正常。
请注意，也可能将MysqL更新为64位，但目前MysqL的安装程序似乎只有32位。您可以通过从官方MysqL站点下载的.zip文件进行安装，尽管它具有64位二进制文件。
了解您已安装的：
>对于Python，只需转到命令行并键入python。它应该显示什么版本，如果它是一个32位或64位安装如此
Python 2.7.10 (default,May 23 2015,09:40:32) [MSC v.1500 32 bit (Intel)] on win32
>对于MysqL，最简单的方法可能是安装在哪个文件夹中。如果安装到Program Files /，那么它是64位，但如果安装到Program Files(x86)/它是32位
