Answer 1

我将ejs.renderFile更改为res.render并且有效。

res.render('s.ejs', { data: results } , function(err, result)

Answer 2

您不需要指定view的路径，快递模板提供以下知识：

res.render('s.ejs', {data: 'some data'});

如果在视图中有用户目录，并且在profile.ejs内，则只需res.render('user/profile.ejs')，依此类推。

错误：ENOENT：没有这样的文件或目录，打开'./views/s.ejs'Nodejs Express
