控制檯中的「Rails s」或「Rails c」失敗：「看起來像您的應用程序的./bin/rails是由Bundler生成的存根」

以下是輸出。究竟是怎麼回事？控制檯中的「Rails s」或「Rails c」失敗：「看起來像您的應用程序的./bin/rails是由Bundler生成的存根」

使用Rails 3.x.我試過「寶石清理」，然後「捆綁安裝」沒有效果。

有沒有人遇到過這個？

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

您是否試過通過捆綁包來運行命令？錯誤日誌中指出：

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)

因此，嘗試運行，像這樣：

> bundle exec rails c 
> bundle exec rails s

修正了它。我沒有意識到捆綁與控制檯有任何關係，所以我打了折扣。感謝您的幫助 - 將在10分鐘內接受您的答案。 – 2014-10-08 09:54:38

@WillTaylor很高興能幫到你！如果您不通過控制檯中的bundler調用命令，它將使用系統上可用的任何寶石，這些寶石可能與您的gemfile中的寶石有不同的版本。 – Matt 2016-03-10 10:06:47

@Matt感謝它修復了它，但它仍然寫道通知：「看起來像你的應用程序的./bin/rails是一個由Bundler生成的存根......這裏是如何提高」..... .......你有什麼想法如何永久修復？每次我想使用控制檯時，我都不特別喜歡打包bundle exec rails。任何建議讚賞。 – BKSpurgeon 2016-03-17 02:47:45

像一隻猴子的工作電腦，我接着軌輸出的指示和它的工作就像一個神聖的奇蹟對我來說：

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

我希望它適用於將來嘗試使用它的所有人。（當然你需要刪除註釋 - 這是包括＃符號後面的單詞）

+1「猴子在電腦上工作」在我使用導軌的過程中，哈哈我總覺得自己像個猴子在電腦上工作......這就是魔法的代價！ – medBo 2016-07-10 15:23:49
