生成RSpec时出错

我已经创建了一个新的Rails项目目录，并且刚刚编辑了.gem文件；我正在学习迈克尔·哈特尔的教程。我现在有了修改后的.gem文件。它在我在命令提示符下运行的“rails生成rspec:install”旁边声明；但是，它现在给了我以下错误：

有人能帮我吗？

查看您的错误消息，它显示

未初始化常量\u Canvi

。这意味着当代码运行时，它正在寻找一个同名的常量（很可能是一个类），但是rails找不到它。对于ruby社区来说，这实际上是一个奇怪的命名约定。作为提示，在创建一个新的rails应用程序时，您应该将应用程序的名称全部用小写字母表示，然后用下划线分隔每个单词

在您的示例中，我建议使用

rails-new\u-canvi

。这将使用常量TheCanvi作为主应用程序类名生成应用程序。这对您的所有模型、控制器等都是一样的

由于这只是一个新教程，请尝试删除该应用程序，然后重新开始。不管怎样，习惯于构建一个新的应用程序总是一个很好的做法

希望有帮助

谢谢你，伙计；那太好了，非常感谢你的反馈。
