Python3.8.1环境下无法安装mysql==0.0.2问题求助

问题概述 #

在Python3.8.1环境中可正常安装mysql==0.0.3，但安装mysql==0.0.2时触发setuptools相关错误，核心报错为AttributeError: 'list' object has no attribute 'split'。

解决方法 #

临时解决（强制安装mysql==0.0.2） #

• 降级setuptools到兼容版本，执行：

  pip install setuptools==44.0.0
  

• 再次尝试安装mysql==0.0.2：

  pip install mysql==0.0.2
  

• 安装完成后可升级回新版setuptools：

  pip install --upgrade setuptools
  

长期推荐方案 #

mysql是官方标记的虚拟包，本身不提供实际功能，仅作为占位存在。建议直接安装成熟的MySQL驱动包，比如：

• 安装pymysql：

  pip install pymysql
  

• 或安装官方驱动mysql-connector-python：

  pip install mysql-connector-python
