Cannot import name 'url_quote' from 'werkzeug.urls'

[jcpayne]

Wonderful tutorial -- thanks so much. I ran into an import error on the catnip example, in the run command:

sudo docker run -p 8888:5000 <username>/catnip
#ImportError: cannot import name 'url_quote' from 'werkzeug.urls' (/usr/local/lib/python3.8/site-packages/werkzeug/urls.py)

Docker Engine on Kubuntu

I second this, great tutorial so far, but I also get ImportError: cannot import name 'url_quote' from 'werkzeug.urls' (/usr/local/lib/python3.10/site-packages/werkzeug/urls.py) when I run the docker file. As you might see, even changing from python 3.9 in your example to 3.10 doesn't fix the issue.

I run Docker Engine on Ubuntu

Full error: Traceback (most recent call last): File "/usr/scr/app/./app.py", line 1, in <module> from flask import Flask, render_template File "/usr/local/lib/python3.10/site-packages/flask/__init__.py", line 7, in <module> from .app import Flask as Flask File "/usr/local/lib/python3.10/site-packages/flask/app.py", line 28, in <module> from . import cli File "/usr/local/lib/python3.10/site-packages/flask/cli.py", line 18, in <module> from .helpers import get_debug_flag File "/usr/local/lib/python3.10/site-packages/flask/helpers.py", line 16, in <module> from werkzeug.urls import url_quote ImportError: cannot import name 'url_quote' from 'werkzeug.urls' (/usr/local/lib/python3.10/site-packages/werkzeug/urls.py)

@jcpayne jcpayne I found a workaround:

• in your docker-curriculum / flask-app there is a file called requirements.txt
• change the Flask version to 3.0.0 and set the Werkzeug version to 3.0.0. The file looks like this now:

  Flask==3.0.0
  Werkzeug==3.0.0

• Save and exit.
• again run docker build -t /catnip .
• there will be a red warning about this is a development server which you can ignore.
• type in your browser 127.0.0.1:5000
• enjoy cat gif :)

That's great @dwolf42 , thanks! It works for me too.

@dwolf42 fixed the issue for me

Alas did not solve the issue for me. Gives me an error: 2.481 ERROR: Could not find a version that satisfies the requirement Werzeug==3.0.0 (from versions: none) 2.482 ERROR: No matching distribution found for Werzeug==3.0.0

Saw a mention of werzeug version 2.2.2, tried that version to, same error.

To bad, really liked the way this tutorial was going

The following worked for me in the requirements.txt file:

Flask==2.0.2 Werkzeug==2.2.2

@jcpayne jcpayne I found a workaround:

* in your docker-curriculum / flask-app there is a file called requirements.txt

* change the Flask version to 3.0.0 and set the Werkzeug version to 3.0.0.
  The file looks like this now:

Flask==3.0.0
Werkzeug==3.0.0

* Save and exit.

* again run docker build -t /catnip .

* there will be a red warning about this is a development server which you can ignore.

* type in your browser 127.0.0.1:5000

* enjoy cat gif :)

Hi @dwolf42 I wasn't able to solve the problem with this approach. Could you help me? I have tried all possible ways that I have found. I am using Ubuntu, Python 3.10.12, Flask 3.0.3, Werkzeug 3.0.2

[dwolf42]

Hey @Programador04, sorry for the late reply. I would love to help you out here, but unfortunately I’m just someone who happens to find a workaround by chance.

If changing the stuff I mentioned inside the requirements.txt didn’t work for you, only @prakhar1989 could be able to give a helping hand.

You can change the Python version to 3.6 in the Dockerfile, it will work.
