I recently ran into an issue on my development box. I can run my script line by line fine within the interactive shell, but it fails as soon as it tries to import a module when running the script from the command line.
Specifically, I'm trying to use:
from flask import Flask
and the error I get is:
from flask import Flask ImportError: cannot import name Flask
It was working perfectly fine a couple days ago and I didn't make any changes to the system (that I can recall) so I can't figure out if this is an issue with my python shell or flask.
Things I've checked/tried:
successfully running the following script to test my python shell:
from time import gmtime, strftime print strftime("%a, %d %b %Y %H:%M:%S +0000", gmtime())
I'm open to any new troubleshooting suggestions.
I had originally called the file flask.py and there was an old compiled flask.pyc in the same directory. It worked fine as soon as I moved it to another directory and also when removing the old flask.pyc.
Thanks for the quick comments timc and BrenBarn!
I made a stupid mistake of naming my script file
nltk.py. So when I imported
nltk, it didn't show an error. When I tried calling any functions, it displayed an error.
Make sure that this doesn't happen.
