角生成-未捕获的TypeError:无法读取未定义的属性'id' [英] Angular Build - Uncaught TypeError: Cannot read property 'id' of undefined

问题描述

我已经设法将我的角度应用程序开发为开发版本.我还没有将其作为生产版本来完成，因为它给了我一些错误，我只需要测试开发版本即可.

I have managed to build my angular app out as a dev build. I haven't done it as a production build yet as it gives me a few errors and i just need to test the dev build.

开发人员的构建过程可以正常进行，没有任何错误或任何错误.然后，我使用Nginx泊坞窗容器中dist文件夹中的文件来托管文件.

The dev build process goes fine, no errors or anything. I then use the files from the dist folder in a nginx docker container to host the files.

问题是什么都没有显示，只有白页，并且在控制台中我收到一条错误消息，提示未捕获的TypeError:无法读取未定义的属性'id'".下面的完整消息似乎没有指向我所写的任何内容，我花了几个小时在网上进行搜索，但找不到有关此问题的任何信息.

The problem is nothing is displayed but a white page and in the console i get an error saying 'Uncaught TypeError: Cannot read property 'id' of undefined'. The full message below doesn't seem to point to anything i have written and i've spent several hours searching online but can't find anything on this problem.

我尝试了一些不同的操作，例如运行"npx ivy-ngcc"(我手动阅读该文件会编译一些内容).无论如何，我是否可以获得有关该错误的更多详细信息，以查看它是否已完成?

I've tried a few different things such as running 'npx ivy-ngcc' which i read manually compiles some stuff. Is there anyway i can get more details on the error to see if it's something i have done?

更新 因此，我恢复了在main.ts中注释掉的行，如下面的注释中所述.我还按照建议尝试了"ng build --aot"，这给了我一系列错误，这些错误似乎都与使用的devextreme组件有关.当我使用来自github的devextreme角启动器项目启动该项目时，我感到很奇怪.

UPDATE So i have restored the line that i commented out in main.ts as mentioned in the comments below. I have also tried 'ng build --aot' as suggested which presents me with a series of errors that all seem to relate to devextreme components that are used. I find this strange as i started the project with the devextreme angular starter project from github.

我收到如下消息:

1. 'dx-scroll-view无效的HTML元素'

1. 'dx-scroll-view is not a valid HTML element'

'node_modules/devextreme-angular/ui/drawer.d.ts-错误:出现在 SideNavOuterToolbarModule的NgModule.imports，但无法解析为NgModule类'

'node_modules/devextreme-angular/ui/drawer.d.ts - error: appears in the NgModule.imports of SideNavOuterToolbarModule, but could not be resolved to an NgModule class'

推荐答案

我设法通过在角度编译选项中禁用常春藤来解决该问题.我一完成，它就可以同时构建开发版本和生产版本，并且现在可以在Nginx中完美运行.

I managed to solve the problem by disabling ivy in the angular compilation options. As soon as i did that it worked building both dev and production versions and is now working perfectly within Nginx.
