角的Zone.js讨厌RaphaelJS

Question

我尝试在角中使用RaphaelJS，但zone.js不想这样：

我浏览了编译后的源代码，仍然没有任何线索。所以我试着解决它安装各种shims，没有工作。

 *   2. Application imports. Files imported after ZoneJS that should be loaded before your main
 *      file.
 *
 * The current setup is for so-called "evergreen" browsers; the last versions of browsers that
 * automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
 * Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.

Answer 1

"ERROR" TypeError: e is undefined Stack trace:

错误的原因是使用变量而不定义。

(function(){"use strict";e})()

修复

定义e

您的错误指向一个缩小的文件。这意味着您发布的代码本质上是无用的。设置源代码映射以获得正确的错误行并从那里开始。
