几天前我刚刚在 rails 上安装了 ruby，每次在控制台中创建一个新项目时，我都会收到以下消息：
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 mingw, mswin, x64_mingw, jruby`.
但是当我尝试安装时：
bundle lock --add-platform mingw
我收到了这条消息：
Could not locate Gemfile
你们知道我对这条消息做了什么吗？？？
