似乎无法更新 bin/ 中的 Rails 可执行文件

Question

我有一个 rails 项目，我在其中使用 bin/rails 而不是仅仅调用rails它自己。 升级到 Rails 4.2 后，我做到了：

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 /Users/Adam/Documents/Rails-Projects/Libraries-and-Helpers/Xaaron/.bundle/gems/gems/railties-4.2.0/lib/rails/cli.rb:5:in `<top (required)>'
    from /Users/Adam/Documents/Rails-Projects/Libraries-and-Helpers/Xaaron/.bundle/gems/gems/railties-4.2.0/bin/rails:9:in `require'
    from /Users/Adam/Documents/Rails-Projects/Libraries-and-Helpers/Xaaron/.bundle/gems/gems/railties-4.2.0/bin/rails:9:in `<top (required)>'
    from bin/rails:16:in `load'
    from bin/rails:16:in `<main>'

所以我认为我可以做，在做完bundle config --delete bin之后：

rake rails:update:bin

但后来我得到了：

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

我

从我创建的 rails 引擎的根上运行它。我很好奇发生了什么。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。

Answer 1

基于问题注释的正确答案是运行：

rake app:rails:update:bin

在引擎的根部。
