Question

less-rails 3.0.0 in Rails 4 project causing Asset logical path has no extension error on asset compilation

ShaneBoyer opened this issue 7 years ago · comments

After a bundle update moved less-rails from 2.8.0 to 3.0.0 asset compilation fails with the error trace below. Pinning less-rails back to 2.8.0 results in successful asset compilation. The change log doesn't indicate any breaking changes. This is from a rails 4.2.x project. The files in the logical path folder are less files (they have .less extensions). Thanks!

Hello!

Is it possible to prepare demo application?

Shane Boyer · Answer 2 · Thu Oct 05 2017 20:06:33 GMT+0800 (China Standard Time)

We don't have one at the moment. Will try to put one together over the next few days.

We attempted to create a new rails 4.2.x project to demonstrate the issue and were unsuccessful. It will be a while until we can untangle the dependencies to find the root cause. For now we're stuck with pinning less-rails to 2.8.0 to keep our project operating. Closing this issue for now.

I'm really sorry @ShaneBoyer for this issue, but without reproducible state I can't solve it :( If you're really in trouble, feel free to ping me in my email (in my GH profile) and we can try to debug this privately.
