UN and debug buttons gray after PyCharm creates a project

I don’t know why, but every time I open it, there is a progress bar in the lower right corner that says to build an index for all the files and wait until he’s done

I don’t like to use some integrated environment, I think such a black box is not used to, generally only install a pure Python, what library to install what, take over the computer used by others really bad, different habits, all kinds of things are not used to

The interpreter is generally in file – Settings – project —- Python interpreter Settings

       

advice

When installing Python, put all the files in one folder, preferably not too deep, (for example, I put the python folder D:\python in the root directory of disk D), the lab computer is not installed by me, directly put, I am very troublesome, and dare not mess with the lab computer
