解决方法

    查了资料 配合自己的环境

    我的mac中没有装mysqlclient 遇到man8没有授权，授权后安装成功

userdeMacBook-Pro:~ user$ brew install mysql-client

Error: The following directories are not writable by your user:

/usr/local/share/man/man8

You should change the ownership of these directories to your user.

  sudo chown -R $(whoami) /usr/local/share/man/man8

And make sure that your user has write permission.

  chmod u+w /usr/local/share/man/man8

userdeMacBook-Pro:~ user$ sudo chown -R $(whoami) /usr/local/share/man/man8

==> Caveats

mysql-client is keg-only, which means it was not symlinked into /usr/local,

because it conflicts with mysql (which contains client libraries).

If you need to have mysql-client first in your PATH run:

  echo 'export PATH="/usr/local/opt/mysql-client/bin:$PATH"' >> ~/.bash_profile

For compilers to find mysql-client you may need to set:

  export LDFLAGS="-L/usr/local/opt/mysql-client/lib"

  export CPPFLAGS="-I/usr/local/opt/mysql-client/include"
