Question

我试图在Visual Studio 2017中运行我的应用程序，但不断出现错误：

 "Error TS2440  (TS) Import declaration conflicts with local declaration of 'PluginConfig'"

我尝试将我的打字稿降级，但是错误并没有消失。以下是我的package.json文件：

以下是角度/ cli版本的屏幕截图：

我尝试在Visual Studio 2017和2019中打开应用程序，但在两个版本的Visual Studio中都遇到相同的错误。我还尝试在Visual Studio本身中更改打字稿版本，但这也不起作用。下面是Visual Studio Typescript版本的屏幕截图：

在解决此错误方面的任何帮助将不胜感激。

Answer 1

显然，这是Typescript的最新版本大于3.6.4的问题。据我所知，在我所使用的版本3.7或3.8中，没有修复此问题。

您可以在根文件夹的tsconfig.json中添加以下内容以使错误消失：

"compilerOptions": {
   ...,
   "skipLibCheck": true
}

此线程中提供了此解决方案： https://github.com/angular/protractor/issues/5348

Answer 2

刚在VSCode和Angular 9中遇到了这个问题。似乎问题出在VSCode从Protractor而不是@ angular / core自动导入EventEmitter。想知道为什么VSCode抱怨EventEmitter没有可用的subscribe（）方法。

import { EventEmitter } from 'protractor';

应该是 import { EventEmitter } from '@angular/core';

更改了导入，一切正常。

错误TS2440（TS）导入声明与“ PluginConfig”的本地声明冲突
