解决方案
To fix your current project and any projects you build with the current version of Express, go to your layout.jade file and change the first line to: doctype html (the second line should read: html)
The issue with is known and has been resolved so it will not be an issue in a future version of Express. https://github.com/visionmedia/express/pull/1875
其他提示
Use :
doctype html
html(lang="en")
change "doctype 5" to "doctype html" on line 1 of views/layout.jade for your brand new project.
