Rails: Sprockets::Rails::Helper::AssetNotPrecompiled in development

Neither of these worked for me (rails-5.0.7, sprockets-3.7.2, sprockets-rails-3.2.1):

config.assets.debug = falseconfig.assets.unknown_asset_fallback = true

But this did:

config.assets.check_precompiled_asset = false

css ruby-on-rails sass

//= link_directory ../javascripts .js

adding this to
app/assets/config/manifest.js
worked for me (working on rails 6)

css ruby-on-rails sass

I've had got the same problem and I fixed it removing all cache files inside tmp folder

rm -rf tmp/cache/assets
