我不确定这是否解决了您的错误，但我按照以下步骤遇到了同样的错误:

  $ rails new hi
  $ cd hi
  $ echo "gem 'annotate', '2.7.1', require: false" >> Gemfile
  $ bundle
  $ rails g annotate:install
  Running via Spring preloader in process 29328
        create  lib/tasks/auto_annotate_models.rake
  (erb):34:in `template': uninitialized constant AnnotateModels (NameError)
          from /home/hibariya/.rbenv/versions/2.3.0/lib/ruby/2.3.0/erb.rb:864:in `eval'
          from /home/hibariya/.rbenv/versions/2.3.0/lib/ruby/2.3.0/erb.rb:864:in `result'
          from /home/hibariya/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/gems/thor-0.19.1/lib/thor/actions/file_manipulation.rb:116:in `block in template'
  ...

我认为这个错误可以通过提前要求 annotate-gem 来修复。因此，当我从 Gemfile 中的 gem 'annotate', '2.7.1', require: false 中删除 require: false 时，错误得到修复。
