未定义的hottowel不是函数。

Question

这是我第一次使用Node.js

我正在学习本教程：http://www.johnpapa.net/get-up-and-running-with-node-and-visual-studio/

我使用Cmder作为命令提示符。

我已经安装了所有组件，我可以查看节点npm bower yeoman grunt的版本。

当我尝试使用: app、serve dev-sync构建应用程序时，输出如下：

F:\Projects\myapp
λ gulp serve-dev --sync

知道我哪里出问题了吗？

Answer 1

我也经历过同样的问题。更改devDependencies在package.json文件中的版本有帮助。设置如下版本：

"gulp-less": "^3.0.0",

和

"gulp-ng-annotate": "^0.5.2",

并运行npm update
