我一直在尝试在运行 ubuntu 18.04 的树莓派上运行 pip3 install mariadb，但没有成功.

I have been trying to run pip3 install mariadb on my raspberry pi running ubuntu 18.04 and I was unsuccessful.

我已尝试按照其他答案中的建议安装以下软件包:

I have tried installing following packages as suggested in other answers:

sudo apt-get install mariadb-server
sudo apt-get install libmariadbclient-dev
sudo apt-get install libmysqlclient-dev

pip3 install mysqlclient
pip3 install mysql-connector-python-rf

我确实有 /etc/mysql/my.cnf 文件.

推荐答案

看来是你没有正确安装MariaDB Connector/C，Ubuntu上的mariadb_config应该在/usr/bin下.

It looks like that you didn't install MariaDB Connector/C properly, on Ubuntu mariadb_config should be found in /usr/bin.

另请注意，MariaDB Connector/Python 需要 MariaDB Connector/C 3.1.5 或更高版本，afaik Ubuntu 18.04 提供 3.0.3 - 所以最简单的方法是下载 Connector/C 源代码并手动构建.

Please also note, that MariaDB Connector/Python requires MariaDB Connector/C 3.1.5 or newer, afaik Ubuntu 18.04 provides 3.0.3 - so simplest way would be to download the Connector/C sources and build it manually.
