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.

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 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!

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
