使用PIP在Windows上编译mysql-python

Question

所以我的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和带有dev工具的MySQL.

我试图通过像pip安装mysql-python:

pip install mysql-python

我收到链接错误:

Answer 1

我有同样的问题和完全相同的错误.我不知道为什么但是

pip install Mysql-python

给了错误.但是当我尝试的时候

easy_install Mysql-python

它工作.我不知道为什么,但它确实有效,但很想知道为什么.

Answer 2

这似乎是您的安装没有检测到 mysql 客户端库。在 mysql 安装中查找 mysqlcppconn.dll 并将其复制到构建脚本读取的文件夹中，例如 windows 文件夹。有关更多信息，请查看此链接https://dev.mysql.com/doc/connector-cpp/en/connector-cpp-apps-windows-visual-studio.html#connector-cpp-application-build-dynamic
