moment.js 时刻未定义 [英] moment.js moment is undefined

问题描述

我刚刚在 Ember.js 应用程序中将 moment@2.1.0 更新为 moment@2.7.0，现在我收到一个错误，当我在控制台中输入 moment() 或将其包含在我的脚本.

I just updated form moment@2.1.0 to moment@2.7.0 in my Ember.js application and now I am getting an error the moment is not defined when I enter moment() into the console or include it in my scripts.

在文档中，我看到自 2.4.0 起，不推荐使用全局导出的矩对象."我认为这是这里的问题，但我不确定如何在 ember 中全局设置 moment，以便我们的代码库中对 moment() 的所有引用当前都不会被破坏.

On the docs I saw "Since 2.4.0 the globally exported moment object is deprecated." which I think is the issue here but I am unsure how I can set moment globally in ember so that all of the references to moment() in our code base currently aren't broken.

我尝试将我们执行 require('moment') 的行更新为 var moment = require('moment') 但结果相同.即使我在 var moment = ... 行之后直接放置一个调试器，然后在控制台中输入 moment() 我仍然得到那个时刻未定义.

I have tried updating the line where we were doing require('moment') to var moment = require('moment') but it has the same result. Even if I put a debugger directly after the var moment = ... line and then enter moment() into the console I still get that moment is undefined.

推荐答案

您想要浏览器新文档的部分.

所以...

<script src="moment.js"></script>
<script>
    moment().format();
</script>

编辑

话虽如此，看起来这可能会给您带来同样的问题.

Having said that, it looks like this will probably give you the same issue.

看起来 Moment.js 试图鼓励您使用包管理器，以免用全局变量弄脏命名空间.

It looks like Moment.js is trying to encourage you to use a package manager in order not to dirty the namespace with global variables.

阅读 CommonJS 和 AMD，并尝试将其纳入您当前的堆栈.

Go read up on CommonJS and AMD, and try and factor it in to your current stack.

你应该这样做:

var moment = require('moment');

moment().format();

但是为了使用require，你需要一个像前面提到的模块系统.

But in order to use require you need a module system like the ones aforementioned.

但是

显而易见的解决方法是回滚您的 Moment.js 版本，只要您不需要新功能即可.一个简单的时间/日期库的更新到底有多重要?

The obvious fix is to rollback your version of Moment.js, so long as you don't need new functionality. How important can an update on a simple time/date library really be?
