ruby-on-rails - 找不到 gem 'rails (= 4.2.4) x64-mingw32'

Question

我最初是在 Windows 中开发我的 RoR 应用程序。现在，由于我发现了一些关于一些 gems、SSH 和其他东西的问题，我决定转向 Linux。我正在尝试启动应用程序，但似乎无法启动。

当我执行 bundle update rails 时，出现以下错误:

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

这是我的 tzinfo-data gem:

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

但是我也已经尝试过这个了:

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

有什么想法吗？因为当我刚刚执行 bundle install 时，我也遇到了以下错误:

You have requested:
  rails = 4.2.4

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

更新:

如果您使用 bundler 和 ruby​​gems 安装 Rails，请确保您的 Gemfile 中有最新版本:

rails '4.2.4'

有 Gemfile.lock 锁定版本。您删除它并再次运行 bundle install。它会起作用。

bundle install
