Question

我正在使用Linux Ubuntu 18.04和python3。我正在尝试在maria-db和我的python脚本之间建立连接。因此，我必须安装mariadb软件包。
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

有人可以帮助我吗？

编辑：

Answer 1

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的版本为3.0.3。

MariaDB Connector/C Download Page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，尤其是非常快的executemany（）方法在MariaDB Server <10.2上会慢得多。

Answer 2

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 3

似乎您需要首先在操作系统上安装它。您可以按照此guide正确安装它。

Python MariaDB pip安装失败，缺少mariadb_config
