I'm just starting out trying to learn to code and I'm trying to get Ruby running for my first time. Ive been searching for over an hour and can't find a solution. When I try to connect to the server i get this error:

C:/RailsInstaller/Ruby2.1.0/lib/ruby/gems/2.1.0/gems/execjs-2.2.2/lib/execjs/runtimes.rb:51:in `autodetect': Could

Then when I try to install execjs and then execjs --source http://rubygems.org the following happens:

C:\Sites\railsbridge\test_app>gem install execjs ERROR: Could not find a valid gem 'execjs' (>= 0), here is why: Unable to download data from https:// rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read serv er certificate B: certificate verify failed (https:// api.rubygems.org/latest_specs.4.8.gz)

I have no idea what I'm doing wrong. I'm running on Windows 7 as well.

Update: execjs installed ok. But when i install therubyracer i get this:

C:\Sites\railsbridge\test_app>gem install therubyracer Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... ERROR: Error installing therubyracer: ERROR: Failed to build gem native extension.

    You need the `nodejs` gem as in [this question](http://stackoverflow.com/questions/24609912/execjsruntimeunavailable-in-rails-4-1-4) – Darshan Rai Jan 27 '15 at 12:48
  • It seems you are using windows OS, So go to this link http://railsinstaller.org/en and download full bundle, it will install all the dependencies to run a rails server, although installing nodejs will solve this problem. – pkrawat1 Jan 27 '15 at 12:52
  • I originally installed ruby and rails from railsinstaller.org. I also just installed node gem, but I still get the same message. – Nathan Dalporto Jan 27 '15 at 13:38

Try to add this in gem file

gem 'execjs'
gem 'therubyracer', :platforms => :ruby
