ruby-on-rails - lockfile_parser.r :48:in `parse_source' : undefined method `[]' for nil:NilClass (NoMethodError)

Question

我第一次搞砸了 RubyOnRails3 和 Git。一切都进行得很顺利，直到突然任何与 rails 相关的命令行参数停止工作。不幸的是，我不知道是什么原因造成的，也不知道如何修复它。

这是命令行的输出

我不确定要提供哪些其他信息

看来 Gemfile.lock 有问题文件。您可以尝试删除此文件并运行 bundle install再次查看它是否可以正确重新创建它。
