Question

我有一个rails项目，我使用bin/rails而不是仅仅调用rails。升级到rails 4.2后，我做了：

rm -rf .bundle/gems
bundle

当一切都完成后，我做了bin/rails

$ bin/rails
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

    from bin/rails:16:in `load'
    from bin/rails:16:in `<main>'

所以我认为在完成bundle config --delete bin之后我可以做到：

rake rails:update:bin

但后来我得到了：

rake aborted!
Don't know how to build task 'rails'

我是从我创建的rails引擎的根目录运行的。我很好奇最新情况。我应该从虚拟应用程序运行此命令吗？我怀疑不是因为bin/目录位于引擎目录的根目录而不是虚拟应用程序。

基于对问题的评论的正确答案是运行：

rake app:rails:update:bin

在发动机的根部。

似乎无法更新bin中的rails可执行文件/
