Problem solving: modulenotfounderror: no module named 'pip‘

Use today pycharm Use pip There was a problem when I went to school
Then I go to the terminal to input pip, Let's see what happened , The result is no ！！！

I updated it before , Just reported an error , Maybe I deleted the old one , No new

This makes it impossible for me to use pip Install other packages , And it can't be updated
