Error: The file/path provided (flaskr) does not appear to exist. Please verify the path is correct. If app is not on PYTHONPATH, ensure the extension is .py

cd .., if you have an issue with the docs please also quote the sentence that is false.

have you done the export FLASK_APP=flaskr step? following the readme in the flaskr example will tell you exact steps (if your not reading the tutorial docs)

[stebogit]

I have a similar issues too.
I followed the readme instructions and I get the following error:

@flaskr:$ pip install --editable .

ImportError: No module named flaskr

Also, what does edit the configuration in the flaskr.py file mean? I guess just SECRET_KEY, USERNAME and PASSWORD?

BTW, in the readme pip install --editable . is missing the space between the editable and the dot (it might sound obvious for most people, but it took me a while to figure it out and make it work since I am COMPLETELY new to Python).

Anyway, I find this Flask very instructive, as a beginner, in its minimalism!
Thanks!

I'm getting the same error in current examples/flaskr (see traceback above). This import statement: from flaskr.flaskr import app (in flaskr/init.py) is not working in Python 2, but does work with Python 3. The relative import works for both, from .flaskr import app. How can I get the explicit import to work for both? What's causing the problem in this case? https://github.com/pallets/flask/tree/master/examples/flaskr

I mistakenly thought the absolute import was a fix here: #2051

[wgwz]

@untitaker if you or anyone else get a chance, please take a look at this for me. in the meantime a fix would be the relative import. apologies to the author of #2051, that's what you proposed and I suggested an incorrect absolute import. i'm still puzzled why it's not working in this case.

[stebogit]

Thanks @wgwz for the quick temporary fix!

[cwdy]

was it solved? sorry i was python 2.7, it doesn't work wether with flaskr.flaskr or with .flaskr.

[wgwz]

for people coming across this thread, the examples repository is located here: https://github.com/pallets/flask/tree/master/examples/flaskr. It's tested on python2 and 3, and works on both. so @cwdy yes, it's been solved. and also, just as friendly note, you might want to post/search on SO for this. see for example: http://stackoverflow.com/questions/37908358.

[cwdy]

Thanks very much @wgwz for your answer.

[SonaArora]

Is this issue fixed or still open?

[untitaker]

Yes it's fixed I think

[SonaArora]

okay. I want to contribute in flask. Can you recommend any other begineer level issue.

[untitaker]

Those come to mind, although I might be underestimating the effort: #2174 #1911 #941 #1877 There's also a lot of stuff in Werkzeug.

In my virtual envrionment and macbook, I met the same problem. it's the problem of command 'flask', my flask command is /usr/local/bin/flask (not using my virtualenv python and flask), use the command 'python -m flask run' instead 'flask run'.
