问题描述
我一直在尝试从Pycharm安装MysqL-Python 1.2.5。 这是我的点子清单： https://prnt.sc/u6ccac
我的python版本：Python 3.7.3 已经安装了MysqLclient： https://prnt.sc/u6cesn
仍然，无法安装MysqL-Python。 这是屏幕截图的错误： enter image description here
这是命令输出：

DEPRECATION: The -b/--build/--build-dir/--build-directory option is deprecated. pip 20.3 will remove support for this functionality. A possible replacement is use the TMPDIR/TEMP/TMP environment variable,possibly combined with --no-clean. You can find discussion regarding this at https://github.com/pypa/pip/issues/8333.
