python - 安装 mariadb 包时找不到 mariadb_config

Question

我尝试在 ubuntu 20.04 上安装 mariadb 软件包，并收到此消息:

Collecting mariadb

      This error typically indicates that MariaDB Connector/C, a dependency which must be preinstalled,
      is not found.
      If MariaDB Connector/C is not installed, see installation instructions
      at: https://github.com/mariadb-corporation/mariadb-connector-c/wiki/install.md.
      If MariaDB Connector/C is installed, either set the environment variable MARIADB_CONFIG or edit
      the configuration file 'site.cfg' to set the 'mariadb_config' option to the file location of the
      mariadb_config utility.

我发现了许多关于此主题的主题和答案，例如更新和升级系统、升级我的 pip 版本或安装 libmariadbclient-dev、setuptools 或 libmysqlclient-dev 等软件包。

我也在我的系统上安装了 libmariadb-dev，但这些解决方案都不适合我。

python3 --版本:Python 3.8.10

pip --版本:pip 22.1.2

感谢您的帮助!

Answer 1

仅安装 libmariadb-dev 是不够的，您还需要安装 libmariadb(据我所知，焦 pip 上是 libmariadb3)，因为 mariadb-config 二进制文件不是 dev 包的一部分。

sudo apt-get install libmariadb3 libmariadb-dev。

另一个选择是安装服务器包，其中也包含 MariaDB Connector/C。
