Error with blocks

[ewandavis]

I'm hitting an error in guess_language with blocks

File ".../microblog/venv/lib/python3.6/site-packages/guess_language/guess_language.py", line 37, in from blocks import unicodeBlock ImportError: cannot import name 'unicodeBlock'

I installed the latest stable version of blocks using the instruction here https://blocks.readthedocs.io/en/latest/setup.html

help("modules") shows block installed

Any pointers?

Thanks

Ewan

I believe you are using an old version of the guess_language library that isn't Python 3 ready. That old version has a blocks.py module that collides with the blocks package of your IDE.

Can you share the output of pip freeze?

Thanks for your response: Here's pip freeze

Looks like I have the latest version of guess-language Thanks Ewan

[miguelgrinberg]

The package is called guess_language_spirit. It is a newer version of the one you installed, which has been dead for many years.

[ewandavis]

Thanks, that,s fixed it .

For anyone else who has the same problem that I did -- for which I don't know the cause -- here was my "solution".

I ran pip install guess_language-spirit; but when I import guess_language, I received the error ModuleNotFoundError: No module named 'blocks'.

I manually deleted all reference to guess_language from my conda env site-packages directory, and then re-installed it via pip install guess_language_spirit.

One of 2 things may have happened:

(1) I accidentally installed pip install guess_language-spirit (underscore then hyphen) -- should this be the same? (2) another package I was using installed pip install guess_language without me realizing it. Thus the cleaning removed versions that I did not realize were installed.

Either way, manually cleaning guess_language* from my env's site-packages directory and re-installing via pip worked for me.

@marimeireles See current version of the Flask Mega-Tutorial on my blog, which uses a different library for language detection.
