无法安装 apache-airflow-providers-mysql：pkg-config 错误

Question

我正在使用 Debian/Ubuntu，并且尝试在我的 Python 虚拟环境中安装 Airflow 提供程序：

手动指定 MYSQLCLIENT_CFLAGS 和 MYSQLCLIENT_LDFLAGS 环境变量，请按照以下步骤操作：

1. 打开终端窗口。

2. 确定 MySQL 头文件和库的位置。这些位置可能会根据您的 MySQL 安装而有所不同。您可以使用该mysql_config命令来检索此信息。运行以下命令来查找头文件的位置：mysql_config --cflags运行以下命令来查找库的位置：mysql_config --libs记下这些命令的输出，因为您在后续步骤中将需要它们。

3. 设置 MYSQLCLIENT_CFLAGS 环境变量。将 `` 替换为从命令中获取的路径mysql_config --cflags。运行以下命令：export MYSQLCLIENT_CFLAGS="-I"

4. 设置 MYSQLCLIENT_LDFLAGS 环境变量。将 `` 替换为从命令中获取的路径mysql_config --libs。运行以下命令：export MYSQLCLIENT_LDFLAGS="-L"注意：如果您的 MySQL 安装包含多个库，请用空格分隔每个库路径。

5. 现在，当您安装需要 MySQL 客户端库的软件包（例如mysqlclientDjango）时，构建过程将使用指定的 CFLAGS 和 LDFLAGS 值来查找必要的文件。您可以继续进行软件包安装或 Django 设置，指定的环境变量将用于查找 MySQL 客户端库。

通过手动设置MYSQLCLIENT_CFLAGS和MYSQLCLIENT_LDFLAGS环境变量，可以确保在安装或编译过程中使用正确的MySQL头文件和库。

我用这个方法解决了和你一样的问题

Answer 2

pkg-config: not found是问题和解决方案的主要提示 - 您缺少构建工具，需要安装它们。

apt-get install pkg-config build-essential libmysqlclient-dev

注意：如果您实际上是在 Docker slim 映像上构建，请参阅：https ://stackoverflow.com/a/77433206/1554386
