Notes on Rails

I solved few errors and I want here to provide how

esbuild and sass missing

Running bin/rails test:system

The error message contains

sh: esbuild: command not found
bin/rails aborted!
jsbundling-rails: Command build failed, ensure `npm run build` runs without errors
sh: esbuild: command not found

As suggested npm run build is a good start
and it show this error message

sh: esbuild: command not found
bin/rails aborted!
jsbundling-rails: Command build failed, ensure `npm run build` runs without errors

the solution is install esbuild, I also suggesto to install sass if you are not sure

npm install --save-exact --save-dev esbuild sass

Running npm run build:css

I see this error:
sh: sass: command not found

the solution is install sass, I also suggesto to install esbuild if you are not sure

npm install --save-exact --save-dev esbuild sass

now npm run build:css and npm run build works and I can finally run my tests
