Pycharm无法安装Python Mysql 1.2.5

分类：编程问答

如何解决Pycharm无法安装Python Mysql 1.2.5

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：

Collecting MySQL-python

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.

pip install pymysql
pip install mysql-connector
pip install mysql-connector-python
