Question

我正在一个有角度的网站上工作。

这是我的生产包。json：

var showInterval = 3000;
var hideInterval=5000;
var myShow = function(){
    clearInterval(interval);
    console.log("show");
    interval = setInterval(myHide, hideInterval);
}
var myHide=function(){
console.log("hide");
 clearInterval(interval);
 interval = setInterval(myShow, showInterval);
}
var interval = setInterval(myShow, showInterval);

我决定在测试服务器上迁移到ng6：

"dependencies": {
    "@angular/animations": "^5.0.2",

  }

自从我进行了这些更改以来，在进行任何新更改后（在Firefox上但在chrome上），我都会出错：

查看文件后，似乎main..js正在将index.html返回给我（所以我理解为什么会抱怨）

让我们举个例子：

在Vn ：我在index.html中引用了main.c26c44b8b53d610233a3.js。

我正在更改ts文件。重建并推送我的更改。

在Vn + 1处：我应该在index.html中引用main.a6b91500af09e35296c4.js

我重新打开浏览器，但出现错误：

SyntaxError: expected expression, got '<  main.<hash>.js:1

当我查看index.html时，仍然引用了main.c26c44b8b53d610233a3.js。

然后，当我刷新时，页面显示良好（因为采用了新的哈希）

有关信息，我的：

SyntaxError: expected expression, got '<  main.c26c44b8b53d610233a3.js:1

我从未更改过构建机制。我一直在奔跑：

<base href="/">

您知道为什么我现在会收到此错误吗？我从没有遇到角度5的错误。

预先感谢

编辑：这不时出现。实际上，它涉及我对js所做的任何更改

致谢

Answer 1

我终于找到了问题的路由原因。

自从我迁移到angular 6以来，我的应用程序捆绑包现在为2.97 MB，超过了sw-precache默认值（2.1）的最大六位数

我在构建日志中找到了

Skipping static resource "dist/main.fd245775d6e1690d968f.js" (2.97 MB) - max size is 2.1 MB

这导致我们让浏览器处理缓存。

要解决此问题，只需在precache配置中添加以下行即可解决问题：

maximumFileSizeToCacheInBytes: 10485760,

Angular 6 SyntaxError：预期表达式，得到了'<
