Question

任何人都可以帮我解决这个问题......实际上rails控制台在Windows命令提示符下崩溃了...我能够运行示例应用程序服务器但无法运行此rails控制台...请和我一起帮助我...提前致谢..

错误是

您的应用./bin/rails看起来像是由Bundler生成的存根。

在Rails 4中，您应用的bin/目录包含版本化的可执行文件像任何其他源代码一样，而不是按需生成的存根。

以下是升级方法：

  bundle config --delete bin    # Turn off Bundler's stub generator
  rake rails:update:bin         # Use the new Rails 4 executables
  git add bin                   # Add bin/ to source control

您可能还需要从.gitignore中删除bin /。

当您安装要在应用中使用其可执行文件的gem时，生成它并将其添加到源代码管理中：

  bundle binstubs some-gem-name
  git add bin/new-executable

此警告说：You have already activa ted activesupport 4.0.0.rc1, but your Gemfile requires activesupport 3.2.8. Using bundle exec may solve this

您只需更新rails gem update rails即可安装依赖项activesupport等。

在更新Gemfile之前，请删除Gemfile.lock

Answer 2

开始使用RVM。将您的宝石放在一个单独的gemset中的项目中，或者只创建一个.rvmrc。你永远不会遇到这样的问题。

然而，我曾经遇到同样的错误并卸载了宝石并重新安装它为我工作。

卸载gem：

gem uninstall <gem_name>

如果系统上有多个版本的gem，它将提示删除版本。

然后，安装一个gem：

gem install <gem_name_with_version>

无法运行rails控制台
