我試過了：

• 升級 setuptools: pip install --upgrade setuptools ,
• 安裝python-devel ， python3-devel ， mysql-devel
• 安裝 mariadb: yum install mariadb-devel給出錯誤

我正在使用centos7： CentOS Linux release 7.9.2009 (Core)

我在 centos7 中使用 docker 容器嘗試了這個，沒有遇到任何問題。

Answer 1

正如@Luuk 在評論中所說，您正在嘗試使用 pip 命令而不是 sql 本身安裝到 mysql 的接口。 這就是您收到以下OSError的原因

>>> OSError: mysql_config not found

首先，您應該按照他們的網頁中的說明安裝 mariadb

$ sudo yum install mariadb-server

然后運行一組命令

$ sudo yum install python3-devel mysql-devel
$ pip install mysqlclient

另請注意，docker 容器中的所有內容都可以正常運行，因為它就像一台單獨的機器。
