Trouble starting rails server. What's the catch?

Question

Ruby on Rails

I'm starting to learn Ruby on Rails and I'm running into a bunch of gem problems... After installing the bundle, the rails server stopped running... Then the error itself:
C:\Users\JulyTab\Documents\Diplom\StudyWorld\StudyWorldPr>rails server
C:/RailsInstaller/ Ruby2.1.0/lib/ruby/gems/2.1.0/gems/bundler-1.12.0.pre.1/lib/bundler/runtime.rb:81:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'less-rails'. (Bundler::GemReq

Help me figure it out (reinstalled the gems mentioned in the errors). Thanks in advance!

Answer 1

There was an error while trying to load the gem 'less-rails'. (Bundler::GemRequireError)
Gem Load Error is: uninitialized constant V8::JSError

A couple of years ago, there was a problem that RubyInstaller did not want to work with V8 - the JavaScript engine.
So you swear that an error occurs while loading the less-rails gem, saying that I don’t know what V8 is.
Alternatively, try downloading the gem 'therubyracer', platforms: :ruby

Answer 2

I see that you are torturing the rail with Windows. I sincerely advise you to set up a Linux environment. Through Vagrant for example.
Otherwise, the shoals will not stop. You will spend a lot of time on the selection of gems that work normally with wines.
