导入错误：这是 MySQLdb 版本 (1, 2, 4, 'beta', 4)，但 _mysql 是版本 (1, 2, 5, 'final', 1)

Question

我已经按照以下步骤在 mac 上安装了 MySQL-python：

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

然后测试一下：

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：

导入错误：这是 MySQLdb 版本 (1, 2, 4, 'beta', 4)，但 _mysql 是版本 (1, 2, 5, 'final', 1)

请帮我解决这个问题。

我在运行 Python 程序时遇到了这个错误airflow：

问题

$airflow
Traceback (most recent call last):

    from airflow import configuration

(version_info, _mysql.version_info))
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 位于：/home/will/.local/lib/python2.7/site-packages/MySQLdb/. cat release.py该目录中的A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"

使固定

为了使版本匹配，我运行了以下内容并为我修复了它：

# 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

您可以重新安装MySQLdb-python并安装此版本：MySQLdb-python-1.2.5

    pip uninstall MySQL_python
    pip install -Iv https://pypi.python.org/packages/source/M/MySQL-python/MySQL-python-1.2.5.zip#md5=654f75b302db6ed8dc5a898c625e030c
