I have a project in PyCharm that its debugger began crashing after I added a few lines of code. I deleted all the code and left a simple print in the file.
The code is located in the folder: "heapq\test_heapq.py" as shown in screenshot 1.
The error I get is "ImportError: cannot import name 'heappush'" as shown in screenshot 2.
What causes this error?
