RAILS ASSETS PIPELINE

When running rake assets:precompile RAILS_ENV=production over ES6 syntax, assets pipeline got broken. If we instead call rake assets:precompile with environment set to RAILS_ENV=development it perform fine.

I was trying to precompile assets on local to serve on production.

CodePudding user response：

You have basically 2 options to fix this:

If you want to use Uglifier gem, change to: config.assets.js_compressor = Uglifier.new(harmony: true), see: https://github.com/lautis/uglifier#rails
You can also use Terser gem: config.assets.js_compressor = :terser (in fact, newest Rails switched to Terser, see: https://github.com/rails/rails/pull/42622)

CodePudding user response：

I got success by changing to config.assets.js_compresor = :terser on production.rb and then calling rake assets:clobber.

Very thanks to @markets that insist on their solution that finally proved to be the right one.
