我正在用rails做简单的hello world项目，但似乎它向我抛出了捆绑器错误。我想看看如何删除我输入后出现的捆绑器错误
rails new helloproject
控制台中的错误包括：

There was an error in your Gemfile, and Bundler cannot continue.
我想知道如何克服此错误并正确捆绑应用程序？
我确实设法运行服务器并运行hello world应用程序，但是每个新项目似乎都会抛出此捆绑器错误。
我已经检查过类似的问题，但这似乎是错误的独特类型。
如何摆脱这些捆绑器安装错误？
检查以下步骤，
gem install bundler
and after adding:
gem 'bundler'
在config/boot.rb的第 2 行（紧接着需要 'rubygems' ）
如果没有解决，请告诉我。
