ImportError:这是MySQLdb版本(1，2，4，'beta'，4)，而_mysql是版本(1，2，5，'final'，1)

Question

我已经在mac上安装了MySQL-python，其过程如下：

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

然后测试它：

python -c "import MySQLdb"

当我测试它时，它在我的mac终端上给了我以下错误：

ImportError:这是MySQLdb版本(1，2，4，'beta'，4)，而_mysql是版本(1，2，5，'final'，1)

请帮我解决这个问题。

当我运行airflow程序时出现了这个错误

问题

$airflow

ImportError: this is MySQLdb version (1, 2, 5, 'final', 1), but _mysql is version (1, 4, 1, 'final', 0)

背景

我使用的MySQLdb是：/home/will/.local/lib/python2.7/site-packages/MySQLdb/。该目录中的cat release.py显示了1.2.5 final 1。

__author__ = "Andy Dustman <farcepest@gmail.com>"
version_info = (1,2,5,'final',1)
__version__ = "1.2.5"

Fix

为了使版本匹配，我运行了下面的代码，并为我修复了它：

# for some reason, even though I had mysqlclient==1.4.1 from pip freeze, I had to uninstall it first, then reinstall
pip uninstall mysqlclient
pip install mysqlclient==1.4.1

Answer 2

在这条路下：

/Library/Python/2.7/site-包

在我的mac上，我可以看到MySQL_python-1.2.5-py2.7.egg-info和MySQLdb只是删除了MySQL_python-1.2.5py2.7的文件，MySQLdb-info/可以修复这个问题：

sudo rm -rf MySQL_python-1.2.5-py2.7鸡蛋-info/

Answer 3

这是一个兼容性问题。我所做的是将mysql设置为1.2.4b.4。

如果已安装mysqldb，请卸载

pip卸载MySQL-python

然后用相同的版本安装：

安装mysql-python==1.2.4b4

这是测试版，所以b

这对我有用。我通过使用python进行交互进行了测试。

然后导入MySQLdb，它就成功了。希望这能有所帮助
