Pycharm升级pip

对于一个Python初学者，实在走了不少弯路，最近须要yong用Flask，Pycharm给我带来了不少便利，可是当我想要经过pycharm安装Flask-Bootstrap时，老是提醒以下错误：You are using pip version 10.0.1,however version 18.0 is available.python

依样画葫芦输入 python -m pip install --upgrade pip，获得以下结果3d

就这样失败了！一阵搜索，有网友提示解释器配置那试试。即以下图：blog

神奇的pip已是18.0版了，但仍是不能用。经过刚才的报错ip

咱们可以知道pip10所在路径，找到它，而后hen狠心地删掉它。把刚才升级起来的18.0也删掉。get

设置以下图，已不见pip的踪迹。pycharm

提示，packaging tools not found，点击后面的install packaging tools进行安装，安装完成后再次出现pip。it

再次运行>python -m pip install --upgrade pip，即可完成pip升级。pip
