bukuserver bails with error from werkzeug.urls

[r0max]

After following the installation instructions for bukuserver with pip3 from PyPi (https://github.com/jarun/buku/blob/master/bukuserver/README.md#installation), bukuserver fails to start with the following error:

(env) ~$ bukuserver run help
Traceback (most recent call last):

from werkzeug.urls import url_decode_stream
ImportError: cannot import name 'url_decode_stream' from 'werkzeug.urls' (/home/r0max/env/lib/python3.9/site-packages/werkzeug/urls.py)

What am I missing?

…Not sure how you managed to install it since the recent pip versions refuse to install both the latest PyPI version (4.7.1) and the latest release (4.8) which wasn't even published at PyPI for the same reason 😅
(See discussion in #685)

As for the error you're getting, the function werkzeug.urls.url_decode_stream() was deprecated and set for removal in werkzeug-2.4; there is currently a workaround implemented, but it wasn't present at the time of 4.8 release.

In other words, you can either downgrade werkzeug package manually, or install the nightly build instead:

pip install "buku[server] @ git+https://github.com/jarun/buku"

Thank you! The nightly build worked on first attempt. I have tried quite a number of other routes before, including downgrading werkzeug, but hit other walls.
