谁能帮我解决这个问题...实际上rails控制台在Windows命令提示符下崩溃...我可以运行示例应用程序服务器但无法运行此rails控制台...请帮助我...提前致谢..

错误是

看起来您的应用程序./bin/rails是由 Bundler 生成的存根。

在 Rails 4 中，您的应用程序bin/目录包含与任何其他源代码一样版本化的可执行文件，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/。

当你安装一个你想在你的应用程序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

这个警告说：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 railsgem update rails即可安装依赖项 activesupport 等。

在更新您的 Gemfile 之前，删除Gemfile.lock

开始使用 RVM。将项目的 gem 放在单独的 gemset 中，或者只创建一个 .rvmrc。你永远不会遇到这样的问题。

但是，我曾经遇到过同样的错误，卸载 gem 并手动重新安装它对我有用。

卸载gem：

gem uninstall <gem_name>

如果系统上有该 gem 的多个版本，它将提示删除该版本。

然后，安装一个 gem：

gem install <gem_name_with_version>
