ruby-on-rails - 即使 ActionCable 已从应用程序和系统中完全删除，Rails 应用程序仍会发出 GET 请求/电缆路由

Question

我想从我的 Rails 应用程序中删除 ActionCable，我找到了 this它表示用所有 rails 组件 gems minus gem 'action_cable' 替换 Gemfile 中的 gem rails。我这样做了，然后从 gemfile.lock 中手动删除了操作电缆

# gem 'rails', '5.2.0'
gem 'activerecord', '5.2.0'
gem 'activemodel', '5.2.0'
gem 'actionpack', '5.2.0'
gem 'actionview', '5.2.0'
gem 'actionmailer', '5.2.0'
gem 'activejob', '5.2.0'
gem 'activesupport', '5.2.0'
gem 'railties', '5.2.0'
gem 'sprockets-rails'

Gemfile.lock:

rails (5.2.0)
 #bye bye action cable
 actionmailer (= 5.2.0)
 actionpack (= 5.2.0)
 actionview (= 5.2.0)
 activejob (= 5.2.0)
 activemodel (= 5.2.0)
 activerecord (= 5.2.0)
 activestorage (= 5.2.0)
 activesupport (= 5.2.0)
 bundler (>= 1.3.0)
 railties (= 5.2.0)
 sprockets-rails (>= 2.0.0)

为了安全起见，我使用了现在非常情绪化 rake assets:clobber 命令。但是当我启动服务器时，日志表明与 actioncable 相关的内容仍然存在:

我什至运行了 gem uninstall action_cable 并从我的系统中删除了所有版本。为什么它困扰着我？ ActionCable 变成了一个无解的麻烦。

Answer 1

首先，如果您从 gemfile 中删除 gem，然后运行 ​​bundle install , 它只会安装你的 gemfile 中的 gem 并且应该已经更新了 gemfile.lock ，但它不会从您的系统中卸载 gem。

但是您必须通过调用 gem install <gemname> 从系统中删除 gem .
