Read-only file system, mkdir /node_modules

Hey, guys!

I’m trying to deploy my rails 7 app with tailwind and esbuild. Locally I run it with Dockerfile and docker-compose.

But I receive this error on render:

error Error: EROFS: read-only file system, mkdir '/node_modules'
info Visit for documentation about this command.
rails aborted!
jsbundling-rails: Command install failed, ensure yarn is installed
Tasks: TOP => assets:precompile => javascript:build => javascript:install
(See full trace by running task with --trace)

Any ideas?

I see that you’ve already initiated a support ticket with us. To avoid any confusion or duplicate efforts, let’s continue the conversation there

Thanks for the support, Jeremy.

Just sharing the solution with everybody, my assets.rb was adding “/node_modules” to the assets path. So, it was trying to create the node_modules in the root, which is not allowed.

I just removed the “/” and it worked, now creating the folder in ~/project/src.
