PIP在Windows上安装MySQL python在python 64位时失败，但在使用32位时成功

我正在Windows上使用Python2.7做一些遗留工作，如果使用一个32位的Python-2.7虚拟环境，并调用“pip安装——强制重新安装——无缓存目录MySQL Python”，就完成了所有工作

但是，如果使用64位的Python-2.7，它将失败，并在下面附加错误。我注意到消息“-IC:\Program Files（x86）\MySQL\MySQL Connector C 6.0.2\include”，这意味着编译器试图包含32位文件，尽管这是一个64位Python环境

除此之外，你能给我一些关于如何修复这个错误和实际安装这个Python包的建议吗

为了验证，我确实需要一个新的安装选项--no cache dir。谢谢你的帮助

DEPRECATION: Could not build wheels for MySQL-python which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

或

或

或者可以从lfd.uci.edu/~gohlke/pythonlibs/#mysql-python安装控制盘

您不需要安装visual studio生成工具。
作为一种解决方法，我通过使用
--全局选项
调用
pip install
命令来指定include和lib文件的路径，从而解决了这个问题。请参见下面的示例命令：

pip install MySQL-python ^
 --global-option=build_ext ^
 --global-option="-IC:\my\install\MySQL-x64\MySQL Connector C 6.0.2\include" ^
 --global-option="-LC:\my\install\MySQL-x64\MySQL Connector C 6.0.2\lib\opt"

注意，我已经完全明白了
pip install mysql-connector-python

pip install MySQL-python ^
 --global-option=build_ext ^
 --global-option="-IC:\my\install\MySQL-x64\MySQL Connector C 6.0.2\include" ^
 --global-option="-LC:\my\install\MySQL-x64\MySQL Connector C 6.0.2\lib\opt"
