Python MariaDB pip 安装失败，缺少 mariadb_config

Question

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

But when i try:

pip install mariadb

I get following error:

Collecting mariadb
  Using cached mariadb-1.0.0.tar.gz (78 kB)

Can anybody help me?

Edit:

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

Answer 1

Install MariaDB Connector/C, which is a dependency.

sudo apt-get install libmariadb3 libmariadb-dev

Use PIP to install MariaDB Connector/Python.

pip3 install mariadb

Answer 2

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.

An actual version of Connector/C for bionic is available on the MariaDB Connector/C Download Page .

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.

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.

Answer 3

It seems you need to install it first on your OS. You can follow this guide to install it properly.
