找不到模块“popper.js"Angular 5 Visual Studio 2017 asp.net 核心 [英] Cannot find module "popper.js" Angular 5 Visual Studio 2017 asp.net core

问题描述

我将 Angular 的版本从 4 更新到 5.下面是屏幕截图，我按照链接

它与 asp.net core Visual Studio 2017 中的 angular 4 模板完美配合.当我将包更新到 Angular 5 时，我收到了如上所述的错误.

我试图用谷歌搜索解决方案，但无法找到解决方案.

解决方案

我在我的项目中修复了同样的问题:

1) 将 popper.js 添加到 package.json 文件中(我看到你已经有了这个)，然后运行npm install":

"popper.js": "^1.12.9",

2) 在 boot.browser.js 文件中添加一个 Import popper.js 语句在 import bootstrap 语句之前:

import 'popper.js';导入引导程序"；

I updated my Angular's verision from 4 to 5. Below is the screenshot, I followed the instruction as per the link http://www.talkingdotnet.com/upgrade-angular-4-app-angular-5-visual-studio-2017/

It was working perfectly with angular 4 template in asp.net core Visual Studio 2017. When I update the package to Angular 5, I'm getting an error as described above.

I tried to google the solution, but not able to find the solution.

解决方案

I fixed the same problem in my project by:

1) Adding popper.js to the package.json file (I see you already have this), and running "npm install":

"popper.js": "^1.12.9",

2) Adding an Import popper.js statement to the boot.browser.js file before the import bootstrap statement:

import 'popper.js';
import 'bootstrap';
