rarwe/bower_components/jquery/src/Intro.js中的语法错误:意外标记(45:0)

Question

我一直在关注Ember.js的摇滚教程。我是在一个Arch虚拟机上做的。

当我使用ember serve时，我会得到：

SyntaxError: rarwe/bower_components/jquery/src/intro.js: Unexpected token (45:0)
  43 | // you try to trace through "use strict" call chains. (#13335)
  44 | //"use strict";
> 45 | 
     | ^

在谷歌搜索之后，我发现至少还有一个人经历了同样的错误，但没有人对此做出解释。

Answer 1

在你的应用程序目录中应该有一个bower_components目录。bower_components应该只在根目录上。

> Remove the bower_components directory
> Remove the tmp directory on root

这将会起作用
