角度9：“为差异加载生成ES5束…”时出错：直接在数字后面的标识符

Question

我刚刚把我的Angular项目从版本8更新到了版本9。由于我必须支持IE11浏览器，目标是“es5”。

更新后，我在“为差异加载生成ES5捆绑包”时遇到以下错误

[1m[31mAn未处理的异常发生：C:\myproject\polyfills-es5.9b276c87455e9832d96d.js:编号（1:354893）[39m[22m[1m[31m[39m[22m]后的标识符

有什么线索可以说明解决办法吗？

Answer 1

同样的问题在我的项目，我解决了设置输出哈希为无（angular.json）。有人有关于这个错误的消息吗？我在github角项目上找不到任何问题，在网络上也找不到任何其他文章。

Answer 2

一些补充资料：

polfst-es5.

{preventExtensions:function(t){return c&&o(t)?c(i(t)):t}})}},[[4,0]]]),polyfills,es5.e52fb6e508fabacaf778.js;
//# sourceMappingURL=polyfills-es5.e52fb6e508fabacaf778.js.map

当且仅当哈希值以数字开头时，才会发生编译错误。

角度设置sourceMap:false。json似乎可以防止错误，在本例中不生成包含文件名的表达式。
