在 ubuntu20 中安装了 mysqlclient
,遇到了不少错误,原因在于 mysqlclient
需要依赖一些动态链接库,还有就是和 python
版本有关系
环境介绍:
ubuntu20 出厂自带 python3.8 ,但是我自己安装了 python3.9
使用命令:sudo apt install python3.9
便可以安装 python3.9
子标题:
- 安装Python mysqlclient出现“OSError: mysql_config not found”错误
- 跨系统 python 版本安装 python3.9-dev
- 为 ubuntu20 安装 python3.9-dev
- ubuntu 自带的 python 是3.8 ,怎么给 3.9 安装 mysqlclient

解决方法:
sudo apt install libmysqlclient-dev python3-dev
如果你使用的 python 解释器的版本是和系统自带的 python 版本一致 ,那就没有问题。
如果你用的不是系统自带的 python 解释器(版本一致就没有问题),继续往下看

因为我用了 3.9 ,之前的命令是装的 3.8 对应的dev,所以会找不到
使用如下命令解决问题
sudo apt install python3.9-dev
