如何从`@ types` typescript 2.0导入类型定义

I'm using typescript 2.0 with the lastest ionic@RC.0 build process.

我正在使用最近的ionic@RC.0构建过程的typescript 2.0。

I installed the google-maps types like this:

我安装了google-maps类型，如下所示：

npm install @types/google-maps --save-dev --save-exact

npm install @ types / google-maps --save-dev --save-exact

and I'm trying to import some of the type definitions into my code like this

我正在尝试将一些类型定义导入到我的代码中

/// <reference types="google-maps" />
import { LatLng, LatLngBounds } from 'google-maps';

but I get this typescript error:

但我得到这个打字稿错误：

./node_modules/@types/google-maps/index.d.ts has no exported member 'LatLng'

./node_modules/@types/google-maps/index.d.ts没有导出成员'LatLng'

and if I look in the source, I actually find the definition in

如果我查看源代码，我实际上找到了定义

./node_modules/@types/google-maps/node_modules/@types/googlemaps/index.d.ts

./node_modules/@types/google-maps/node_modules/@types/googlemaps/index.d.ts

2 个解决方案

#1

You are checking the wrong declaration file. The one you are using is: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/google-maps/index.d.ts which does not expose LatLng.

您正在检查错误的声明文件。您使用的是：https：//github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/google-maps/index.d.ts，它不会公开LatLng。

The declaration file you linked to is: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/googlemaps/index.d.ts

您链接到的声明文件是：https：//github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/googlemaps/index.d.ts

googlemaps vs google-maps

googlemaps vs google-maps

The import only works for the current package, not its dependencies.

导入仅适用于当前包，而不适用于其依赖项。

So you need to import { LatLng, LatLngBounds } from 'googlemaps'

所以你需要从'googlemaps'导入{LatLng，LatLngBounds}
