谁能帮我解决这个问题？
谢谢
最佳答案
如果您不想经历卸载和重新安装 Node 的麻烦，您可以使用 npm Github 上的补丁手动编辑位于“npm/node_modules/npm”路径下的“lib/outdated.js”文件网站 npm "outdated -g" patch
修复就像在一行中添加“|| 'global'”一样简单。工作正常，并将保持原位，直到下一次 npm 更新。

我已经从我的命令行中获得了一切，所以我可以运行rubymyfile并且它可以正常工作。但是当我尝试从sublime中运行它时，我得到了undefinedmethod`require_relative'formain:Object有人知道我的sublime设置中缺少什么吗？我正在使用OSX并安装了rvm。 最佳答案 或者，您可以只使用“require”，它应该可以正常工作。我认为“require_relative”仅适用于ruby1.9+ 关于ruby-主要:Objectwhenrun
我花了三天的时间用头撞墙，试图弄清楚为什么简单的“rake”不能通过我的规范文件。如果您遇到这种情况:任何文件夹路径中都不要有空格!。严重地。事实上，从现在开始，您命名的任何内容都没有空格。这是我的控制台输出:(在/Users/*****/Desktop/LearningRuby/learn_ruby)$rake/Users/*******/Desktop/LearningRuby/learn_ruby/00_hello/hello_spec.rb:116:in`require':cannotloadsuchfile--hello(LoadError) 最佳

似乎无法为此找到有效的答案。我正在阅读Rails教程的第10章第10.1.2节，但似乎无法使邮件程序预览正常工作。我发现处理错误的所有答案都与教程的不同部分相关，我假设我犯的错误正盯着我的脸。我已经完成并将教程中的代码复制/粘贴到相关文件中，但到目前为止，我还看不出我输入的内容与教程中的内容有什么区别。到目前为止，建议是在函数定义中添加或删除参数user，但这并没有解决问题。触发错误的url是http://localhost:3000/rails/mailers/user_mailer/account_activation.http://localhost:3000/rails/mai
