I am using Linux Ubuntu 18.04 and python 3. I am trying to build a connection between a maria-db and my python scripts. Therefore I have to install the mariadb package.
I have already installed:

sudo apt install mariadb-server

但是当我尝试时:

I have now been able to connect to the server but not with te mariadb package. (https://linuxhint.com/connect_mariadb_pymysql/)

推荐答案

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

To install mariadb python module, you have to install a recent version of MariaDB Connector/C, minimum required version is 3.1.5, afaik Ubuntu 18.04 has 3.0.3.

上提供了用于仿生的 Connector/C 的实际版本MariaDB 连接器/C 下载页面.

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.

If you want to install it in a special directory, make sure that the PATH and LD_LIBRARY_PATH point to bin and lib directories.

我还建议使用最新版本的 MariaDB Server，尤其是非常快的 executemany() 方法在 MariaDB Server 上会慢得多

10.2.

I also recommend to use a recent version of MariaDB Server, especially the very fast executemany() method will be much slower on MariaDB Server < 10.2.
