安装@ types/leaflet后无法访问全局L名称空间 [英] Unable to access global L namespace after installing @types/leaflet

问题描述

我正在努力获取对传单的导出名称空间的引用.我的TypeScript项目中的类型定义.

I am struggling to get a reference to an exported namespace for the leaflet type definitions in my TypeScript project.

使用npm install --save @types/leaflet安装类型后，我的TS编译器(我正在使用VS Code)可以在类型定义文件中找到某些导出的类和接口，例如转换，类，但是我无法访问导出的任何名称空间.

After installing the types using npm install --save @types/leaflet my TS compiler (I am using VS Code) is able to find some of the exported classes and interfaces in the type definition file, e.g. Transformation, Class, but I am unable to access any of the namespaces exported.

我需要能够引用L全局变量，以便可以调用Leaflet API，但是编译器不会为我准备.

I need to be able to reference the L global so I can make calls to the leaflet API, but the compiler is not picking this up for me.

我确实尝试过在TS文件中使用import语句，例如，尝试在其中使用传单

I did try using an import statement in my TS file I am trying to use leaflet in, e.g.

import * as L from 'leaflet'

但是同样，这次我仍然只能使用导入的别名访问类\接口，例如L.Transformation

But again, I can still only access the classes\interfaces this time on my imported alias, e.g. L.Transformation

我无法初始化新地图，例如，由于无法使用L，因此无法使用L.map(...)-

I cannot initialise a new map, e.g by using L.map(...) since L is not accessible for me - map is an exported function in the type definition file

所以我不确定如何在我的项目中引用和使用L全局传单.

So I am unsure how to reference and use the L global for leaflet in my project.

任何人都可以帮忙吗?

谢谢

推荐答案

尝试使用旧版本的@ types/leaflet.我有同样的问题，并通过使用1.0.69版本解决了. npm install --save @ types/leaflet @ 1.0.69

Try using an older version of @types/leaflet. I have the same issue and solved it by using the 1.0.69 version. npm install --save @types/leaflet@1.0.69

使用高于(1.2+)的值似乎会导致此错误.

Using anything above that (1.2+) seems to lead to this error.
