ARM 64 - node sass issue

[JeffKatzy]

I followed the tutorial for installing tutor with arm-64 here (including running the tutor dev dc build lms command).

When I get to the final step, tutor dev start, I run into the following error.

#12 74.70 gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.
#12 74.70 gyp ERR! stack     at PythonFinder.failNoPython (/openedx/app/node_modules/node-gyp/lib/configure.js:484:19)

I believe this is related to the following.

I am not sure if the Can't find Python executable "python", you can set the PYTHON env variable. is another issue.

Was able to get further by changing the dockerfile to perform a find and replace on node-sass in the package.json file with the following:

# Install nodejs requirements
ARG NPM_REGISTRY=https://registry.npmjs.org/
COPY --from=code /openedx/edx-platform/package.json /openedx/edx-platform/package.json
WORKDIR /openedx/edx-platform

RUN sed -i 's/.*node-sass.*/"sass": "^1.49.8",/' /openedx/edx-platform/package.json

RUN npm install --verbose --registry=$NPM_REGISTRY

However, now I run into the following issue when performing tutor local start.

Potentially fixed the above by installing tutor-mfe, with the fix to the dockerfile described here. However, now running into a new error.

73 39.79 ERROR in ./src/index.scss

There's definitely an ARM64 binary:
https://packages.ubuntu.com/jammy/gifsicle
But, if you'll click to the "arm64" link you'll end up in a page saying that it's not in the repository:
https://packages.ubuntu.com/jammy/arm64/gifsicle/download

The solution is to track down the Launchpad build process and get the deb files from its artifacts:
https://launchpad.net/ubuntu/+source/gifsicle/1.93-2/+build/22295342

Since there are no complicated dependencies you should have the binary installed pretty easily, but that's just half the story.

In that case I'm seeing some peculiar stuff:
imagemin/gifsicle-bin#124 (It's not a real dependency, it's just Unicode garbage).
https://www.npmjs.com/package/gifsicle (I'm trying to understand if this package is really needed as it's executing the gifsicle binary directly).
I'm trying to think if there's anything that can be done in that aspect with Node 12.

Guys, please discuss your issues in the forum. Do not use GitHub issues to troubleshoot your installation. Come back to GitHub once you have identified a precise problem. See: https://docs.tutor.overhang.io/troubleshooting.html
