这是我的Angular代码中正常的ES5函数:
app.run(function($templateCache){ $templateCache.put('/some','thing') });
我想将其转换为ES6箭头功能
app.run($templateCache => $templateCache.put('/some','thing'));
但是它给出了错误
Uncaught Error: [$injector:unpr] Unknown provider: '/some'Provider <- '/some'
http://errors.angularjs.org/1.4.6/$injector/unpr?p0='%2Fsome'Provider%20%3C-%20'%2Fsome'

ES6箭头功能是否与Angular不兼容?
编辑:我想也许Angular无法推断名称$templateCache
,因此无法注入它,但后来我将其记录到控制台并确实正确显示:
app.run($templateCache=>console.log($templateCache));
// =>
// Object {}
// destroy: function()
// get: function(key)
// info: function()
// put: function(key, value)
// remove: function(key)
// removeAll: function()
// __proto__: Object

正确。 Your version of AngularJS is not compatible with arrow functions that make use of $injector.
这主要是因为AngularJS 1.4.6使用(Function).toString
,它不以function(
开头的箭头函数,至少在Firefox中是这样的:
>var a = () => 5
function a()
>a.toString()
"() => 5" // not "function a() {return 5;}"
AngularJS支持1.5.0 onwards的箭头符号。

我尝试了另一个有效的变体:(x)=>…
(而不是x=>…
)
app.run(($templateCache) => $templateCache.put('/some','thing'));
我想由于某种原因它需要括号
