"tutor images build openedx" failed

Hi everybody!
I have a strange error when I try to build the openedx image when installing the “indigo” theme. Please find the error bellow:

For information, I just upgraded tutor to the 10.0.9.

Any idea?

Thank you very much! :slight_smile:

Good catch @florianbusi! It seems that pycontracts==1.8.14 was pulled from pypi. A PR was opened an hour ago to backport the fix in edx-platform: https://github.com/edx/edx-platform/pull/24376
I’ll make a new tutor release that cherrypicks this change.

By the way, how can we help you with your wonderful Tutor? We are just starting up so for the moment we cannot afford to take the LTS, but we really want to help :pray:t3:
Merci pour tout :clap:t3:

Dear @regis
New problem just after the upgrade from 10.0.9 to 10.0.10
The “tutor image build openedx” works like a charm, but when I try to start the stack (“tutor local quickstart” or “tutor local reboot”), the following error occurs:

docker-compose -f /home/tutor/.local/share/tutor/env/local/docker-compose.yml -f /home/tutor/.local/share/tutor/env/local/docker-compose.prod.yml --project-name tutor_local up --remove-orphans

The stack cannot start :face_with_raised_eyebrow: :smile:

Any idea?

Do you prefer that I move this new bug to a new topic?

Thanks a lot :pray:

There was a problem with building the new images. Please wait a few minutes more and they should be published to dockerhub.

I encountered today the same problem trying to build a local image for version 10.2.2 (similar builds for the very same version did not have any such issue).

ERROR: Could not find a version that satisfies the requirement py2neo==3.1.2 (from -r ./requirements/edx/base.txt (line 183)) (from versions: 4.0.0, 4.1.0, 4.1.1, 4.1.2, 4.1.3, 4.2.0, 4.3.0, 2020.0.0, 2020.1.0, 2020.1.1, 2021.0.0, 2021.0.1)
ERROR: No matching distribution found for py2neo==3.1.2 (from -r ./requirements/edx/base.txt (line 183))

Any ideas why this happens? Is there a workaround?


There is fix in open edX master branch, please refer to below two commits. The general idea is use github version of py2neo instead of PyPI. @galas

I just ran into this exact error when trying to build a local image for 10.5.3.

I’ll outline my fix below. I have no idea if it is the correct way of fixing this, but it worked for me. If anyone has a better solution, please let me know.

I downloaded a copy of base.txt from github here: edx-platform/base.txt at open-release/juniper.master · edx/edx-platform · GitHub

I then modified line line 184 from:

py2neo==3.1.2 # via -r requirements/edx/base.in



I copied the new base.txt file into ~/.local/share/tutor/env/build/openedx/requirements

I then made the following change in the Dockerfile:


# Install base requirements
RUN pip install -r ./requirements/edx/base.txt


# Install base requirements
COPY ./requirements/base.txt ./requirements/edx/base.txt
RUN pip install -r ./requirements/edx/base.txt

I then rebuilt the images and everything worked.

Again, if there is a better solution to this, I’m all ears.


Hi all!

@ToddLichty Your workaround works like a charm! Really appreciated the detailing of the process. As an update I observed building at last again my local images that the linked version of base.txt from the source code is already fixed with the new github repo for py2neo.

Again many thanks for the help from all!

Thanks @ToddLichty this worked great!
