我是 Ruby 和 Rails 的新手。我一直遇到兼容性问题，任何帮助将不胜感激！
我试图在 | 中运行 rspec 的文件目录的一些背景这是我正在上的在线课程的文件。它根据需要包含一个 lib 和 spec 文件。但我得到的错误似乎是我的 rspec 下载的问题。
编辑 Rails 应用程序根目录中的 .rspec 文件，并将以下行从：
|
1
|
—format nested
|
到：
|
1
|
—format documentation
|
rspec-3.0 中不再存在 nested 格式。
- 您不必投票，但如果它解决了您的问题，您需要将答案标记为已接受。
卸载所有以前版本的 rspec 及其依赖项。
