i've a problem with PyCharm v2.7.
it does not show me errors.
i've configured it to show them as here
but nothing.
here a screenshot of what i see (no error displayed)
if i run code analysis it shows the errors marked as INVALID in the window but it does not highlight the code. any idea?
I had this issue recently on PyCharm 2020.3.3 Community Edition.
What I've found is in the top right corner of the editor there is a Reader Mode button.
If you click it you turn the Reader Mode off and then you can see your errors.
You can re-enable it by clicking the book icon
In my case, I had some ticks disabled in the Python Inspections menu in Settings > Editor > Inspections > Python. I have ticked everything and applied, and now it is working.
I don't really understand why this happened as the problem arose from one day to another. I had even re-installed the whole PyCharm, trying older versions, and deleted the .pycharm configuration folder from home.
None of the previous answers worked for me when I ran into this issue, but I was able to fix it by doing a hard reset on my PyCharm settings:
From the main menu, select File | Manage IDE Settings | Restore Default Settings.
You will lose all your custom settings this way of course, but this was the only thing that worked for me.
I have tried many things, but only Invalidate Caches did the trick, after that I could hover the green arrow (top right side) and change Highlight to All Problems
I just faced a similar issue. I ran my web with IIS so I didn't have an interpreter on my Pycharm project, when I added my virtual environment interpreter everything returned to work. I hope this will help someone in the future
