This is because you have a too old version of Relatorio installed. You need at least version 0.7.0.

This looks like ImportError: cannot import name Response (#8671) · Issues · Tryton / Tryton · GitLab, which was fixed quite some time ago.

Are you sure your Tryton installation is up to date?

aso · January 9, 2021, 2:09pm

am using a back up of tryton of another person , who already worked with this tryton on his debian , i just create a virtual environement on my linux then i installed some packages on my debian 10 and i copied the files of the backup into the virtual environement i created , i created the database postgresql then i typed the command (-a) .
but there is something i want to know it everytime i typed the command (-a) , the response was also a warning on the response of linux :
UserWarning: Unable to load plugin ‘chart’ warnings.warn(“Unable to load plugin ‘%s’” % name)

is it normal !!

dave · January 9, 2021, 2:24pm

Does the backup contain only the data, or the whole Tryton installation?

Is it possible that, in the virtual environment you created, you have a newer version of Werkzerg than they had on their system?

This may be because you need some additional Python packages installed for the chart plugin (pycha >= 0.4.0 and pyyaml)?

aso · January 9, 2021, 2:41pm

i did “pip install pycha “then “” pip install pyyaml” , the same warning happen , is this warning causes the error"cannot import name ‘Response’ from ‘werkzeug.exceptions’ (/home/lenovor/.virtualenvs/mynewproject/lib/python3.7/site-packages/werkzeug/exceptions.py)”!?

dave · January 9, 2021, 2:47pm

No, I don’t think they are related.

I believe the warning is because relatorio can’t load the chart plugin (which is probably not going to be a problem for you).

I think the error is because the version of Werkzeug is newer than the version supported by the release of Tryton that you are running.

aso · January 9, 2021, 3:36pm

am a beginner on those things , i see this link that u mentionned to solve the problem of the werkzeug
[Issue 8671: ImportError: cannot import name Response - Tryton issue tracker]
but i do no how to use it to solve my problem , can u guide me please what i should d !o

dave · January 9, 2021, 3:44pm

If Issue 8671: ImportError: cannot import name Response - Tryton issue tracker is the cause of your problem you should update the trytond package to a release that has that fix already applied. You should also pick a release in the same series as you are already running (the series is the first 2 parts of the version number, so for version X.Y.Z ensure the X.Y part stays the same).

aso · January 9, 2021, 6:27pm

i update the trytond using the command
pip3 install trytond==5.6.
but always when i type the command (-a) it tell me the same error “cannot import name Response”

dave · January 9, 2021, 6:46pm

What is the output when you type:

trytond/bin/trytond-admin --version

aso · January 9, 2021, 7:00pm

the response when typed is :
trytond-admin 5.2.1

edbo · January 9, 2021, 9:35pm

With your virtual environment active do a

pip list installed

And look for the package Werkzeug. For your version is should be 0.16.1. If not do

pip install --upgrade Werkzeug==0.16.1

aso · January 11, 2021, 9:16am

i fixed it with the version 0.15 from werkeug , and now it tell me there is no module named “edifact” , i tried with pip install edifact , but it tell me give the version !! , what’s the version od edifact i should put to install “edifact”

ced · January 11, 2021, 9:30am

No standard module depends on edifact.

aso · January 11, 2021, 10:37am

when i type the command : trytond/bin/trytond-admin -c trytond.conf --all -d test-tryton -vv
it tell me :

from edifact.message import Message
ModuleNotFoundError: No module named ‘edifact’
so what i should do , thanks in advance .

ced · January 11, 2021, 10:48am

Ask the question to the author of this module. It is not a standard Tryton module so nobody here can know what you have installed and what are the dependencies of this unknown module.

aso · January 11, 2021, 11:25am

yeah thanks i deleted the module depends on , but after that when i typed the command : trytond/bin/trytond -c trytond.conf --dev
to launch the tryton , there is on error : 3033 139947999958848 [2021-01-11 11:10:42,122] MainProcess ERROR trytond.modules.product_barcode.product Unable to import barcodenumber. Install barcodenumber package.

This is another non-standard module, so again you need to talk to the author of this module.
