AttributeError: 'CachedHTTPResponse' object has no attribute '__attrs_init__'

[gbloeb]

Description of the bug

When trying to run nf-core download (or nf-core list) I get the error:
AttributeError: 'CachedHTTPResponse' object has no attribute '__attrs_init__'

I have tried installing via bioconda or within a conda environment as suggested.

Full context below:

Same issue here...

Can you try the current dev version of nf-core/tools, which you can download via: pip install --upgrade --force-reinstall git+https://github.com/nf-core/tools.git@dev

[ewels]

We did fix some stuff to do with downloading the latest rnaseq release (#1385, #1379) but this looks different.. 🤔

This stack trace suggests that the error here is something to do with requests_cache and caching of API responses. It looks like it's coming from that dependency rather than any nf-core code.

Could you please try:

• Deleting the nf-core API cache: ~/.nfcore/cache_3.7 (or something similar)
• Installing the latest version of requests_cache: pip install --upgrade requests_cache
• Running with the development branch of nf-core/tools, as suggested above by @mashehu

[gbloeb]

Running with the development branch of nf-core/tools fixed this for me. Thank you!

Great stuff! I'll close for now, can reopen if more people hit the issue.

Should be releasing a new version of tools any day now.
