使用 Pip 安装 Python 3.9 后导入模块出错

Question

Apologies, but I'm a total python newbie and I'm really stuck with this. I've got Python 3.9 on a PC, and am learning to code using PyCharm as my editor. I've used Pip to import numpy but I'm getting an error when I add "import numpy" to my script: ModuleNotFoundError: No module named 'numpy'

It looks like Pip downloaded it okay, and put it into the folder: C:\Users\Alastair Heptonstall\AppData\Local\Programs\Python\Python39\Lib\site-packages\numpy

PyCharm appears to be using the correct version of python (it has Python 3.9 in the lower right corner of the screen). And it looks like the version of Pip I used is the one that came with Python 3.9.

Is this error caused by a path not being set correctly?

Thanks for any help, very much appreciated!

Answer 1

You can try this

1. Open PyCharm .

2. go to File -> settings -> Project:untitled1 (untitled1 means your project name) -> select project interpretor -> click add button

3. after clicking add button and search <package name> then install it.

finally, run the program.

Newer versions of Pycharm have a " + " mark (add button) here.
