I have a Rails 6 app I return to sporadically. It's using webpacker for the JS, and Sprockets for the CSS (as I think is default). If relevant, I'm developing on WSL - the files are in the Ubuntu filesystem, Rails is running in Ubuntu, editing is using VSCode remotely into the WSL.
Today, running in development environment, I made a change to one of the SCSS files and refreshed my page. The served CSS did not update; Sprockets has not recompiled it. Stopping and restarting the server did not prompt a recompile (I didn't really expect it to...).
bin/rails assets:precompile
did regenerate; but I wouldn't expect to have to do that in development.
How do I make Rails recompile changed SCSS in the sprockets asset pipeline in development?
Extracts of my files and setups that I think should be relevant:
app/assets/config/manifest.js
//= link_tree ../images
//= link_directory ../stylesheets .css
app/assets/stylesheets/application.scss
/*
*= require_tree .
*= require_self
*/
...
app/assets/stylesheets/
also contains characters.scss
, which is the file I modified.
app/views/layouts/application.html.slim
doctype html
html
head
= csrf_meta_tags
= csp_meta_tag
= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload'
...
config/environments/development.rb
...
# Debug mode disables concatenation and preprocessing of assets.
# This option may cause significant delays in view rendering with a large
# number of complex assets.
config.assets.debug = false
config.assets.compile = true
# ^-- also fails if compile = false
