Rails new --css boostrap failed

[kubatron117]

Error:
Rails::Generators::Error: The template [/usr/local/bundle/gems/cssbundling-rails-1.4.1/lib/install/bootstrap/install.rb] could not be loaded. Error: No such file or directory - npx (Rails::Generators::Error)

How I resolved it:
Firstly, I tried using my custom Docker image. After that, I tried this tool and encountered the same error. I discovered that my Docker image had an old version of Node.js and npm. I updated them, and after that, it started working for my docker image.

Full output from console:
