安装petergate会返回错误`找不到生成器'petergate：install'`

Question

我不断收到此错误。 全文如下：

$ rails g petergate:install
Running via Spring preloader in process 96515
Could not find generator 'petergate:install'. Maybe you meant 'devise:install', 'responders:install' or 'integration_test'
Run `rails generate --help` for more options.

我已经运行过bundle install 。 该gem已安装并位于我的gem目录中。 我知道这不会有所作为，但是已安装Devise，并且我的用户模型称为user.rb

奇怪的是，当我尝试复制问题时，通过创建一个新应用程序并安装devise，然后创建petergate，这一代工作了。

我尝试卸载petergate，将其从捆绑软件中取出并重新放回， bundle / bundle install / bundle update每个组合，将其移至gemfile的顶部，尝试用rails generate而不是用rails g ，重新启动我的电脑，但似乎没有任何作用。

我的Gemfile如下：

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"

有人对这可能有什么想法吗？ 我正在撕头发。

Answer 1

好的，所以我最终解决了这个问题，方法如下。 这是一个非常棘手的解决方案，但是当其他所有方法都失败时...

由于它正在开发一个全新的新应用程序，因此我在运行petergate：install及其之后对这个新应用程序进行了提交。 然后，我推到github并比较了两者。

User.rb的更改实际上非常简单-进行少量迁移，并在User.rb模型中添加了一些文本。 所以我做了同样的事情。 嘿，请记住，它现在正在工作，并且与gem的交互也是如此，所以我不确定问题出在哪里。

在将来您可能需要其他命令行功能或安装进行大量更改的更复杂的gem上，这更可能是一个问题，但是在像这样的简单gem上，似乎好的

希望这对遇到相同（或相似）问题的人有所帮助。
