pip安装mysqlclient报错 Specify MYSQLCLIENT

话不多说，报错如下：

  × Getting requirements to build wheel did not run successfully.  │ exit code: 1  ╰─> [24 lines of output]      Trying pkg-config --exists mysqlclient      Command 'pkg-config --exists mysqlclient' returned non-zero exit status 1.

Specify MYSQLCLIENT_CFLAGS and MYSQLCLIENT_LDFLAGS env vars manually      [end of output]    note: This error originates from a subprocess, and is likely not a problem with pip.error: subprocess-exited-with-error

关键问题就在这一句：

Exception: Can not find valid pkg-config name.Specify MYSQLCLIENT_CFLAGS and MYSQLCLIENT_LDFLAGS env vars manually

异常:找不到有效的pkg-config名称。 手动指定MYSQLCLIENT_CFLAGS和MYSQLCLIENT_LDFLAGS环境变量

 官网上其实给出了解答：

 # Debian / Ubuntu

sudo apt-get install python3-dev default-libmysqlclient-dev build-essential pkg-config 

# Red Hat / CentOS

sudo yum install python3-devel mysql-devel pkgconfig

 Mac 

macOS (Homebrew)

Install MySQL and mysqlclient（如果要index.php/tags-98.html" >安装MySQL）:

$ # Assume you are activating Python 3 venv$ brew install mysql pkg-config$ pip install mysqlclient

If you don't want to install MySQL server, you can use mysql-client instead(不要安装MySQL):

$ # Assume you are activating Python 3 venv$ brew install mysql-client pkg-config$ export PKG_CONFIG_PATH="$(brew --prefix)/opt/mysql-client/lib/pkgconfig"$ pip install mysqlclient
