Python MariaDB pip 安装失败，缺少 mariadb_config

Question

我正在使用 Linux Ubuntu 18.04 和 python 3。我试图在 maria-db 和我的 python 脚本之间建立连接。因此我必须安装 mariadb 包。
我已经安装了：

sudo apt install mariadb-server

但是当我尝试：

pip install mariadb

我收到以下错误：

Collecting mariadb

有谁能够帮助我 ？

编辑：

我现在已经能够连接到服务器，但不能使用 te mariadb 包。( https://linuxhint.com/connect_mariadb_pymysql/ )

Answer 1

安装 MariaDB Connector/C，这是一个依赖项。

sudo apt-get install libmariadb3 libmariadb-dev

使用 PIP 安装 MariaDB Connector/Python。

pip3 install mariadb

Answer 2

要安装 mariadb python 模块，您必须安装最新版本的 MariaDB Connector/C，最低要求版本是 3.1.5，afaik Ubuntu 18.04 有 3.0.3。

MariaDB Connector/C 下载页面上提供了用于仿生的 Connector/C 的实际版本 。

如果要将其安装在特殊目录中，请确保 PATH 和 LD_LIBRARY_PATH 指向 bin 和 lib 目录。

我还建议使用最新版本的 MariaDB Server，尤其是在 MariaDB Server < 10.2 上非常快的 executemany() 方法会慢得多。
