[Deployment] /usr/local/app/node_modules/.bin/node-sass: not found

[mattwang44]

Description

After deploying the 2024 backend on staging environment,

• Access the admin site (<host>/admin/): works fine
• Access proposal system (<host>/): see the error message /usr/local/app/node_modules/.bin/node-sass: not found

Steps to Reproduce

• rebuild the container
• access the proposal system page

Expected Behavior

It should display the page (but it does not).

Actual Behavior

500 response.
After turning on the debug mode, it shows /usr/local/app/node_modules/.bin/node-sass: not found.

Additional context

It should be the side effect of #1151.

Inside the src/pycontw2016/settings/base.py, the line

COMPRESS_NODE_SASS_BIN = node_bin('node-sass')

expected node-sass executable at the patch /usr/local/app/node_modules/.bin. However, after #1151, the path to the node_modules was moved to /usr/local/lib/node_modules/, which causes the exception. But not sure why we did not encounter this after #1511 (maybe we haven't rebuilt for too long?)

For the current staging environment, I fixed it up with a workaround (but it'll still break after rebuild):

> docker exec -it pycontw-2024 bash -c "cp -r /usr/local/lib/node_modules/ /usr/local/app; ls /usr/local/app"
> docker-compose restart web
