我的世界开发者应用无法使用补全库，点补全库提示没找到python2.7，手动选择后跳出命令提示符，命令提示符内容：
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

用在命令提示符中输入python -m pip install --upgrade pip后提示：

这个跳出的内容和手动选择后跳出的一样，问过其他开发者，说是pip的问题，但是忘了怎么弄
