You should install MySQL through Homebrewfirst, to get python-mysql work properly on OS X.

你应该先通过Homebrew安装 MySQL ，让 python-mysql 在 OS X 上正常工作。

pip uninstall MySQL-python
brew install mysql
pip install MySQL-python

Make sure you have the most recent version of Xcode including Command Line Tools. I simply downloaded the 2GB update from the app store. I had a similar problem, specifically this, and that fixed it.

确保您拥有最新版本的 Xcode，包括命令行工具。我只是从应用商店下载了 2GB 更新。我有一个类似的问题，特别是this，并且修复了它。

Cheers!

干杯!

I installed mysql a long time ago with homebrew so when I ran into trouble now after upgrading OSX I reinstalled it again with brew reinstall [email protected](I ran 5.7.10) and reinstalled MySQL-python I expected it to be resolved. Got the error mentioned above.

我很久以前用自制软件安装了 mysql，所以当我在升级 OSX 后遇到麻烦时，我再次重新安装了它brew reinstall [email protected]（我运行了 5.7.10）并重新安装了 MySQL-python 我希望它能够得到解决。得到上面提到的错误。

It really did my head in and after spending several hours on it I had no idea what to do, rebuilt from source and everything. Tried other python apps for mysql but it was the same thing.

它真的让我头疼，在花了几个小时之后，我不知道该怎么做，从源代码和一切重建。为 mysql 尝试了其他 python 应用程序，但结果是一样的。

I somehow realised that the client being built by MySQL-python was against the wrong version so I checked where the /usr/local/opt/mysqlwas linked to and there it was, it was linked to a previous version which I had installed via dmg like 7 years ago! Once I removed that link and then ran brew link mysqland then created a new virtualenv and installed all the packages from scratch it finally worked!

我以某种方式意识到由 MySQL-python 构建的客户端针对错误的版本，所以我检查了/usr/local/opt/mysql链接到的位置，它链接到了我 7 年前通过 dmg 安装的以前的版本！一旦我删除了该链接，然后运行brew link mysql，然后创建了一个新的 virtualenv 并从头开始安装了所有软件包，它终于可以工作了！
