我正在关注 RSpec 测试的一章，但我不断收到load error.
它告诉我首先创建一个新分支，然后创建两个新目录：Models和Spec. 在这些目录中，我应该制作两个文件；models/entry.rb和spec/entry_spec.rb。在 中spec/entry_spec.rb，我应该输入以下代码：
require_relative '../models/entry'
RSpec.describe Entry do
end
然后在我的models/entry.rb我应该把这个代码：
class Entry
end
然后我应该运行这个终端命令：
$ rspec spec/entry_spec.rb
并得到这个结果：
No examples found.
Finished in 0.00015 seconds (files took 0.1186 seconds to load)
0 examples, 0 failures
但是我总是收到这个加载错误，我不知道这是什么意思

var app = express();
app.use(express.static("public"));
app.set("view engine", "ejs");
app.get("/", function(req,res){
res.render("home");
