No need more magic to solve ModuleNotFoundError: No module named 'werkzeug.contrib' as the error message says.

Please check out  your /odoo/requirement.txt  dependancy of werkzeug  ( 0.14.1 in my case),  then install it by :

$ cat /odoo/requirement.txt           and find down the version of werkzeug requirement, then
$ sudo pip3 install werkzeug==0.14.1


Hope this will help

Anyone managed to solve it? I have the same problem.

Hi Elkafil,

I am assuming, that the wrong version of Werkzeug was installed in the fist place. This usually happens, when you have 2 versions of python installed, and you use 'pip' for installing dependencies rather than using 'pip3'. Hope this helped!

I'm having same problem right now. This script has always worked for me until now. Who has a solution please? I have an urgent project I'm supposed to submit soonest

Hi,

I have the same problem, i'm installing a new server with Odoo with the same script thta I have used before many times, but since yesterday I've being having this same error and dont know what to do

i solved this by running these flowing commeds :

python3 -m pip uninstall werkzeug

python3 -m pip install werkzeug==0.16.0

NOTE: find werkzeug version in you requirmnet.txt

My version is odoo11.  And since I install environment in ubuntu16.04. I also got this issue.

After tracing back errors, I got this error.

`Failed building wheel for pyldap`

And after I run this code.
`sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev`
and
`pip3 install -r requirements.txt`

Make sure your werkzeug version in requirements.txt is correct with official document.

then you can execute odoo.

i resolved my problem by using this script for my install 

sudo wget https://raw.githubusercontent.com/Yenthe666/InstallScript/12.0/odoo_install.sh

Try 

pip3 install werkzeug==0.16.0
