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 自身。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>'

所以我假设我可以做，在做 bundle config --delete bin:

rake rails:update:bin

但后来我得到：

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

我正在从我创建的 rails 引擎的根目录运行它。我很好奇发生了什么事。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

根据对问题的评论，正确答案是运行:

rake app:rails:update:bin

在引擎的根部。
