[英]PIP install MySQL-python on Windows fails in Python 64bit but succeeds if use 32bit
我正在 Windows 上使用 Python 2.7 做一些遗留工作，如果使用 Python-2.7 32 位的虚拟环境，并调用“pip install --force-reinstall --no-cache-dir MySQL-python”它完成所有好的。
但是，如果在 64 位中使用 Python-2.7，则会失败并显示以下错误。 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。
除了非官方的轮子之外，您能否给我一些有关如何修复此错误并实际安装此 Python 包的指示？
出于验证的目的，我确实需要使用 --no-cache-dir 选项进行全新安装。 感谢您的帮助。

Failed to build MySQL-python
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.

WARNING: You are using pip version 20.2.2; however, version 20.2.3 is available.
You should consider upgrading via the 'D:\work\test_x64\venv\Scripts\python.exe -m pip install --upgrade pip' command.
(venv) D:\work\test_x64>
尝试安装这些，
pip install pymysql
或者
pip install mysql-connector
或者
pip install mysql-connector-python
或者你可以从 lfd.uci.edu/~gohlke/pythonlibs/#mysql-python 安装轮子
您不需要安装 Visual Studio 构建工具。
作为一种解决方法，我通过使用--global-option调用pip install命令来指定包含和 lib 文件的路径来解决它。 请参阅下面的示例命令：
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"
请注意，我已经在上面示例中给出的自定义位置完全安装了 64 位版本的MySQL-x64\\MySQL Connector C 6.0.2 。 在我的另一个问题的自我发布答案中查看更多详细信息。
最好在基于64位Intel的Mac（Perl / Python用户）上安装MySQL 32位或64位吗？
[英]Better to install MySQL 32bit or 64bit on my 64bit Intel-based Mac (Perl/Python user)?
