大家好，感谢您成为这样一个伟大的社区。
我正在使用rails启动一个新项目，而我已经开始遇到问题了。创建一个新的应用程序后，我试图生成一个新的控制器，以便我可以开始工作，rails正在抛出这个错误。我做了所有固定轨道建议，我也遇到了同样的问题
错误：

run bundle install
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

干净的重新安装修复了我的问题。我不想去那个极端，但这是我唯一的选择......
答案 0 :(得分：1)
尝试使用 <p>One<br>Two<br>Three<br><span style="color:red">Four</span></p>
使用bundle exec rails g controller Welcome index将锁定对您在Gemfile中指定的特定gem的所有调用，而不是全局安装。
尝试评论以下宝石：
bundle exec然后在此完成后运行gem 'spring'
gem 'spring-watcher-listen', '~> 2.0.0'
再次运行命令：bundle update
答案 1 :(得分：0)
尝试将此行添加到您的gemfile
gem pristine bindex --version 0.5.0
也试试
rails generate controller welcome
没有索引方法，稍后手动添加。
答案 2 :(得分：0)
在命令中停止使用bin/rails。使用：
rails g controller Welcome index
