pycharm Python3.6.5安裝flask

報錯如下:

Traceback (most recent call last):

  File "/Applications/PyCharm CE.app/Contents/helpers/packaging_tool.py", line 184, in main

    retcode = do_install(pkgs)

  File "/Applications/PyCharm CE.app/Contents/helpers/packaging_tool.py", line 109, in do_install

    return pip.main(['install'] + pkgs)

AttributeError: module 'pip' has no attribute 'main'

解決方案：

sudo python3 -m pip install Flask
