Suddenly there is no python interpreter when opening the project, and the python interpreter cannot be reconfigured. Moreover, the entire folder is highlighted in yellow, as shown below, and it is useless to reinstall pycharm and even open File–>Setting–>Project. There is no Project option here. It is actually due to the .idea folder. Pycharm does not recognize that your code is a python project.
2. Solution
There are multiple solutions below, the first one I chose is fine
Solution 1: Still in the above folder, change .idea文件夹删掉 under the project to solve the problem, and then reopen the project, and there will be no problem
Solution 2: If deleting the .idea folder does not work, you can try changing the project name and opening it with pycharm again.
Solution three: Re-create a project and move your current files there again.
