upgrade configuration of less due to migrate rails from 3 to 5

Question

Rails migration from v3 to v5 is in progress. Less loading is not worked.

couldn't find file '../less/style.less' under '{root}/app/assets/stylesheets' with type 'text/css'

(seems strange mime type in error message, I suppose may be less must be there)

actually file exists and all was worked before migration, bundle and code changes is performed according to documentation for migration process

also environment configured like this

config.less.paths << "#{Rails.root}/app/assets/stylesheets/less"

Any suggestions to figure out? Any additional request for debug/inspect?

Thanks

Answer 1

Solved by removing the file extension,

so instead:

*= require ../less/theme/style.less

is used:

*= require ../less/theme/style

and the problem disappears
