有人遇到过这种情况吗

Looks like your app's ./bin/rails is a stub that was generated by Bundler.

In Rails 4, your app's bin/ directory contains executables that are versioned
like any other source code, rather than stubs that are generated on demand.

Here's how to upgrade:

  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

You may need to remove bin/ from your .gitignore as well.

When you install a gem whose executable you want to use in your app,
generate it and add it to source control:

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

看起来你的应用程序的./bin/rails是由Bundler生成的存根。
在Rails 4中，应用程序的bin/目录包含版本控制的可执行文件
与任何其他源代码一样，而不是按需生成存根。
以下是如何升级：
bundle config--删除bin#关闭Bundler的存根生成器
rake rails:update:bin#使用新的rails 4可执行文件
git add bin#将bin/添加到源代码管理
您可能还需要将bin/从.gitignore中删除。
当您安装要在应用程序中使用其可执行文件的gem时，
生成并将其添加到源代码管理：
我有一个宝石的名字
git add bin/新可执行文件

您是否尝试过通过bundle运行这些命令？错误日志说明：

You have already activated activesupport 4.0.8, but your Gemfile requires activesupport 3.2.16. Prepending `bundle exec` to your command may solve this. (Gem::LoadError)

所以试着像这样跑步：

> bundle exec rails c
> bundle exec rails s

就像一只猴子在电脑上工作一样，我遵循rails输出的指令，这对我来说就像一个神圣的奇迹：

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

我希望它对将来尝试它的每个人都有效。（当然，您需要删除注释，这些注释是在#符号之后的单词，包括#符号）

修复了它。我没有意识到这个捆绑包和控制台有任何关系，所以我打折了这条线。谢谢你的帮助，我会在10分钟内接受你的回答。@WillTaylor很高兴我能帮上忙！如果您不在控制台中通过bundler调用命令，它将使用系统上可用的任何gems，这些gems可能与gemfile中的版本不同。@Matt感谢它修复了它，但它仍然写下通知：“看起来您的应用程序的./bin/rails是bundler生成的存根……下面是如何升级”……你有没有办法永久修复？我并不特别喜欢每次使用控制台时都输入bundle exec rails c。感谢您的任何建议。@BKSpurgeon我正在使用。你也可以试试。
