找不到 gem 'rails (= 4.2.4) x64-mingw32'

Question

I was first developing my RoR application in Windows. Now since I've been founding a few problems regarding some gems, SSH and stuff I decided to move to Linux. I am trying to initate the application, but It seems I am not able to.

When I do bundle update rails I got the following error:

Could not find gem 'rails (= 4.2.4) x64-mingw32' in the gems available on this
machine.

This is my tzinfo-data gem:

gem 'tzinfo-data', platforms: [:mingw, :mswin, :jruby]

But I have already tried with this one too:

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

Any idea? Because when I just do bundle install I also got the following error:

You have requested:
  rails = 4.2.4

The bundle currently has rails locked at 4.2.4.
Try running `bundle update rails`

Update:

Answer 1

If you've installed Rails using bundler and rubygems, make sure you have the latest version in your Gemfile:

rails '4.2.4'

there is Gemfile.lock which locks the version. You delete that and run again bundle install. it will work.

bundle install

Answer 2

1. Visit https://rubygems.org/gems
2. Search for your gem. Once found, copy the text from the box titled GEMFILE
3. Add the copied text in your Gemfile found inside your app
4. Run bundle from the console opened at the root of your app.

On successful installation of the gems your console will display the message: Bundle complete! xx Gemfile dependencies, xx gems now installed. Bundle complete! xx Gemfile dependencies, xx gems now installed.
