我在Win 8 PC上成功安装了Railsinstaller并启动了一个项目.我设置了 github并将项目推送到它.在第一台电脑上,一切都在找工作.然后我在第二台Win 8 PC上安装了Railsinstaller.在第二台PC上,我运行了gem update rails.然后我运行了git clone [url],这也很成功.但我无法启动rails服务器,因为缺少gem.这是gem列表的输出：

我试过捆绑安装：

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)

和捆绑更新：

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

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

但这没有帮助.我也删除了gemfile.lock并运行了上面提到的命令,但仍然没有运气.我觉得奇怪的是它抱怨了宝石的版本冲突,但是当我查看gem文件时,我看到所有必需的版本都已安装.你能不能指出我可能做错了什么,因为我完全没有想法？谢谢.
