Angular 6-@ types/googlemaps/index.d.ts'不是一个模块 [英] Angular 6 - @types/googlemaps/index.d.ts' is not a module

问题描述

我刚刚更新了package.json文件中的某些软件包.然后在运行npm install之后，我运行ng serve.但是我现在遇到以下错误.

i just updated some packages in my package.json file. Then after running npm install i run ng serve. However i am now getting the following errors.

ERROR in ... File '.../node_modules/@types/googlemaps/index.d.ts' is not a module.
... error TS6137: Cannot import type declaration files. Consider importing 'googlemaps' instead of '@types/googlemaps'

我在这里尝试了建议的解决方案- @ types/googlemaps/index.d.ts'不是模块，在我的component.ts文件顶部添加/// <reference types="@types/googlemaps" />，但这不能解决我的问题，该错误仍然存​​在.

I tried the suggested solution here - @types/googlemaps/index.d.ts' is not a module adding /// <reference types="@types/googlemaps" /> at the top of my component.ts file however this did not fix my problem and the error persists.

/// <reference types="@types/googlemaps" />
import { Component, OnInit, Input, ViewChild, AfterViewInit } from '@angular/core';
import { } from '@types/googlemaps';

推荐答案

您可能在component.ts文件中不需要此行(仅适用于Angular< 6):

You probably don't need this line in your component.ts file (It's only for Angular <6):

import { } from '@types/googlemaps';

这是Angular 6的(基本/最小)示例:

Here's an (basic/minimal) example for Angular 6:

/// <reference types="@types/googlemaps" />
map: google.maps.Map;
this.map = new google.maps.Map(....);

基本上，如果要在Angular< 6中使用它，则必须通过import方法添加它.在Angular 6+中，您必须通过reference方法添加它.您不应该同时添加两者.

Basically, if you want to use it in Angular <6, you have to add it via the import method. In Angular 6+ you have to add it via the reference method. You shouldn't add both at the same time.

希望我能帮上忙.
