ImportError: No module named 'selenium' in PyCharm

From your screenshot, I can see that selenium is not installed. Please follow the next step:

1st solution:

File -> Settings -> Inside your project's name -> Project Interpreter -> click on "+" button -> search for selenium (current version 3.141.0) -> click on install -> restart PyCharm.

2nd solution:

Or click on the selenium word from the first line (from the import) and wait until a solution will be shown. The solution will say install selenium package. Press on it and you are done.

3rd solution:

If you have already installed the selenium then you need to install webdirver. Follow the following screenshot to solve it.

Screenshot for 3rd solution:

Pychram can use more than one environment for running your project. I guess you are using a different environment in which you have installed tools. Change the env by going

File > Settings > Prefrences > Project Interpreter.

Either change that to the local env or click + button below the window and add that package to current env.

You may have it installed in a different env and running pycharm from a different env. The best solution is to go to file then setting then your project and python interpreter. Click on the small + sign and search pycharm and finally click on install to install it. It should work now.
