Pycharm 无法导入数学模块

Question

我无法在 pycharm 中导入标准数学模块，出现错误：“没有名为 math 的模块”，我可以从 python shell 导入它，这是什么原因造成的？

Answer 1

Check that you are pointing to the correct python file within Settings > Project > Project Interpreter.

When I've had this problem in the past my interpreter was pointing at python3.6 and not python within the bin folder of my venv. I simply dropped the interpreter and added it again pointing to the venv-name/bin/python

Answer 2

File >> Settings >> Project interpreter. You should see a list of currently installed packages/libraries. If the module is not specified in there click the plus sign and look for your module in there. Also make sure you specify it correctly when you import it.

Answer 3

I had a similar issue and was able to fix it by creating a new Python system interpreter. Project Interpreter -> Add Local -> System Interpreter -> /usr/local/bin/python3

Answer 4

import math -> 而不是使用 "print(sqrt(25))" 使用 "print(math.sqrt(25))" (这里 sqrt 仅用于 exp.)
