使用 Pip 在 Python 3.8 中成功安装模块但我无法导入它们？

Question

I'm a Python newbie. I have Python 3.8 installed, but my Macbook is running Python 2.7. I wasn't able to install Pip initially, but after looking up some Q&As, I installed Pip using this command:

pip3 install --upgrade --force pip
Collecting pip
  Using cached https://files.pythonhosted.org/packages/54/0c/d01aa759fdc501a58f431eb594a17495f15b88da142ce14b5845662c13f3/pip-20.0.2-py2.py3-none-any.whl

  Found existing installation: pip 19.2.3
    Uninstalling pip-19.2.3:

Successfully installed pip-20.0.2

pip --version
pip 20.0.2 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)

Following that, I installed some modules successfully:

pip install python-docx
Collecting python-docx
  Downloading python-docx-0.8.10.tar.gz (5.5 MB)
     |████████████████████████████████| 5.5 MB 2.4 MB/s

Installing collected packages: lxml, python-docx
    Running setup.py install for python-docx ... done
Successfully installed lxml-4.5.0 python-docx-0.8.10

I can't seem to import them into Python. The "Site Packages" folders are orange, compared to the rest which are grey. I have uploaded a picture below, you can take a look:

Here's the output for pip versions:

which -a pip
/Library/Frameworks/Python.framework/Versions/3.8/bin/pip

which -a pip3
/Library/Frameworks/Python.framework/Versions/3.8/bin/pip3
/usr/local/bin/pip3

Could it be a project interpreter issue? Some screenshots below:

It's not just this module, I can't import all the modules that I have installed using Pip. Please help me! Thanks!! :)

Answer 1

Solved this issue with the help of @DavidCullen and @a_guest

So previously I have installed the modules on the system of my MacBook, but in PyCharm, I was actually in the Virtual Environment. These two didn't link.

After I understood the concept, there are two ways to sort the issue - 1. suggested by @DavidCullen -- run source venv/bin/activate in the Terminal in PyCharm, and then use the Pip commands

2. I was playing around PyCharm and found this option to "Activate Global Site Packages" --

I was able to import my installed modules after these.

Hi i also faced the same problem previously to get out of the problem install it in the powershell or cmd or the place where you are executing the code. this has worked for me.
