我在 Win 8 PC 上成功安装了 Railsinstaller 并启动了一个项目。我建立了github并将项目推送到它。在第一台 PC 上，一切正常。然后我在第二台 Win 8 PC 上安装了 Railsinstaller。在第二台 PC 上，我运行gem update rails. 然后我跑了git clone [url]，那也成功了。但是我无法启动 rails 服务器，因为缺少 gem。这是输出gem list：

tiny_tds (0.5.1 x86-mingw32)

tzinfo (0.3.37)
warden (1.2.3)

我试过bundle install：

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    rspec-rails (= 2.6.1) x86-mingw32 depends on
      railties (~> 3.0) x86-mingw32

    sass-rails (~> 4.0.0) x86-mingw32 depends on
      railties (4.0.0)

和bundle update：

Bundler could not find compatible versions for gem "activesupport":
  In Gemfile:
    rspec-rails (= 2.6.1) x86-mingw32 depends on
      activesupport (~> 3.0) x86-mingw32

    rails (= 4.0.0) x86-mingw32 depends on
      activesupport (4.0.0)

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    rails (= 4.0.0) x86-mingw32 depends on
      railties (= 4.0.0) x86-mingw32

    sass-rails (~> 4.0.0) x86-mingw32 depends on
      railties (4.0.0.rc2)

但这没有帮助。我还删除了 gemfile.lock 并运行了上述命令，但仍然没有运气。我觉得奇怪的是它抱怨 gem 的版本冲突，但是当我查看 gem 文件时，我发现所有必要的版本都已安装。您能否指出我可能做错了什么，因为我完全没有想法？谢谢你。

If bundle says it cannot find compatible gem versions it's probably because it has nowhere to look. You're giving it version numbers, i.e. forcing it to take certain versions for each gem, or versions superior to X, or inferior to X.

Try deleting the version numbers for the culprit gems from your Gemfile and try again:

gem 'rspec-rails'

instead of 

gem 'rspec-rails', '2.6.1'

我刚才在尝试创建 ROR 博客时遇到了同样的问题。解决方案是通过第 5 行和第 9 行 gem 'rails' 和 gem 'sass-rails' 行来编辑您的 Gemfile。删除两行后面有 4.0 版本的部分，然后在终端中保存并重新键入命令。希望能帮助到你。

我解决了所有这些问题-“系统找不到指定的文件路径”等等。解决方案是为您提供正确X:\RailsInstaller\Ruby2.0.0\bin 的路径，有很多 bat 文件并安装在 Windows 上，二进制文件有一些奇怪的路径，就像

C:\users\emechnic\railsinstaller\stage...

我把它换成了我的

X:\RailsInstaller\Ruby2.0.0\bin它工作正常！)
