错误:
Uncaught Error: Cannot enable prod mode after platform setup. at main.bundle.js:1
** Package 盒:**
在使用**ng build --prod
生成构建后,应用程序启动时出错。但是,使用ng serve
或ng build
**编译的开发构建都运行正常。
我尝试的是:
- 按照this答案,将全局和本地
@angular/cli
升级到最新版本,即1.6.0
。

在您在git/cli-reproapp提供的示例应用中,由于以下行而发生错误:-
如果是,则返回一个值。
在文件
cli-reproapp/src/app/app.constants.ts
中。因此,作为一种解决方法,您可以创建一个函数来代替常量isInDevMode
,如下所示。这样,当代码中实际使用isDevMode()
时,它会在以后被调用(最重要的是在调用enableProdMode()
之后)。很明显,在此之后,您还需要将使用“isInDevMode”常量的行更改为对新创建的“isInDevMode()”方法的调用。
与这一个:-
您还可以在链接git/cli-reproapp(working)处查看示例应用的工作版本。

当我在
app.module
中使用函数isDevMode()
并构建我的应用程序时,我发现了这个错误。我用environment.production
替换了它,它解决了我的这个问题。
