我正在使用 OSX 10.8 和 PyCharm 来开发 Python 开发项目。我已经使用网站上的说明为 mac 安装了 MySQL-python

http://blog.infoentropy.com/MySQL-python_EnvironmentError_mysql_config_not_found

但是，运行该项目会给我这个错误：

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: dlopen(/Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so, 2): Symbol not found: _mysql_affected_rows

  Expected in: flat namespace
 in /Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so

提到错误的文件存在于位置 - /Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so

整个错误消息是 -

您应该首先通过Homebrew安装 MySQL ，以使 python-mysql 在 OS X 上正常工作。

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

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 的更新。我有一个类似的问题，特别是this，并且修复了它。

干杯!

我很久以前用自制软件安装了 mysql，所以当我在升级 OSX 后遇到问题时，我再次使用brew reinstall mysql@5.7（我运行了 5.7.10）重新安装它并重新安装了 MySQL-python，我希望它会得到解决。得到了上面提到的错误。

它真的让我很头疼，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，但它是同一件事。

我不知何故意识到由 MySQL-python 构建的客户端是针对错误的版本，所以我检查了/usr/local/opt/mysql链接到的位置，它链接到了我在 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！
