Question

我第一次使用RubyOnRails3和Git。一切都顺利进行，直到所有与轨道相关的命令行参数突然停止工作。不幸的是，我不知道是什么导致了这个或如何解决它。

这是命令行的输出

C:\railstest\railsproject>rails

        from script/rails:5:in `<main>'

我不确定提供哪些其他信息

好像Gemfile.lock文件中存在一些问题。您可以尝试删除此文件并再次运行bundle install以查看它是否可以正确重新创建。

lockfile_parser.r：48：在`parse_source'中：未定义的方法`[]'为nil：NilClass（NoMethodError）
