Cannot install pip (matplotlib) on windows in pycharm-CodePudding

tried program

import matplotlib.pyplot as plt
import numpy as np

xpoints = np.array([1, 8])
ypoints = np.array([3, 10])

plt.plot(xpoints, ypoints)
plt.show()

pip is now installed, after reading michael s question the "pip install matplotlib " works

however the same thing python error is occuring

Try adding pip to your environment variables. Press your Windows icon on your keyboard, then start typing "variables". Click on "Edit environment variables" (pictured below):

In your environment variables, click on "Path" then click "Edit". In the edit window, click "New" then paste your path to your pip executable, which looks to be C:\Users\M0182965\AppData\Local\Programs\Python\Python39\Scripts . Look at my path as an example (the highlighted one is where my pip executable is):

Then just keep hitting "Ok" until your out of all the windows. Open a fresh terminal and try pip install again. You shouldn't have to restart your computer but try it if the above doesn't work.

pip install does not work for the virtual environment for the newest pycharm. You need to install via project interpreter for every project individually.
