cannot import name 'url_decode' from 'werkzeug.urls

[tylerflex]

Hopefully someone can give some guidance. Am not able to import Signac-dashboard due to something with werkzeug.urls.

Thanks in advance for your help!

Description

I installed signac signac-flow and signac-dashboard through pip. (0.6.0).

Then, I tried running the example from the documentation

from signac_dashboard import Dashboard
from signac_dashboard.modules import StatepointList, DocumentList, ImageViewer, Schema

if __name__ == '__main__':
    modules = [StatepointList(), DocumentList(), ImageViewer(context="JobContext"),
               ImageViewer(context="ProjectContext"), Schema()]
    Dashboard(modules=modules).main()

And got the following error

cannot import name 'url_decode' from 'werkzeug.urls'

full trace below

To reproduce

Run the steps above. Note: on MacOS running python 3.10

Error output

@tylerflex This thread has some context: https://github.com/glotzerlab/signac-dashboard/pull/196#issuecomment-1743821052

I think you can work around this by using werkzeug>=2.1.0, < 3.0, but signac-dashboard hasn't made a release with this pinning yet. I think we're hoping this pinning can be handled upstream of signac-dashboard.

Thanks for your response, what worked in the end was

werkzeug==2.3.0
flask==2.1.0

Thank you! feel free to close
