                问题描述

                在我的打字稿项目中,我使用的是whatwg-fetch":2.0.3",这是此多边形填充的最新版本,作为我使用此版本的类型@types/whatwg-fetch":0.0.33当我使用打字稿版本2.2.0"时,一切对我来说都很好.

                In my typescript project I am using "whatwg-fetch": "2.0.3" this is latest version of this poly fill ans as types I am using this version "@types/whatwg-fetch": "0.0.33" and everything works well for me when i used typescript version "2.2.0".

                但是现在我想将 typescript 更新到最新版本2.5.3",这是我的问题,我尝试共同编译它然后我首先得到 bambilon types 错误我得到的是这个错误

                But now I would like to update typescript to latest version "2.5.3" and that is my problem wen I try co compile this then I got bambilon types errors first what i got is this error

                D:ProjectsAppStoreSourceappstoresourceAppStore ode_modules@typeswhatwg-fetchindex.d.ts(11,13): 错误 TS2451: 无法重新声明块范围变量 'fetch'.

                D:ProjectsAppStoreSourceappstoresourceAppStore ode_modules@typeswhatwg-fetchindex.d.ts (11,13): error TS2451: Cannot redeclare block-scoped variable 'fetch'.

                是的,第 11 行是这样声明的

                Yes true is that on line 11 is this declare

                declare let fetch: typeof window.fetch;
                

                或者

                D:ProjectsAppStoreSourceappstoresourceAppStore ode_modules@typeswhatwg-fetchindex.d.ts(13,14):错误 TS2300:重复标识符HeadersInit".

                D:ProjectsAppStoreSourceappstoresourceAppStore ode_modules@typeswhatwg-fetchindex.d.ts (13,14): error TS2300: Duplicate identifier 'HeadersInit'.

                所以有人尝试使用whatwg-fetch"和最新的打字稿,或者我潜在的问题是在加载程序等方面,对我来说,看起来我有两个定义或者我不知道......我迷路了:-) ???

                So did some one try use "whatwg-fetch" and latest typescript or I potential problem is in something like loaders etc, for me it looks like I have two definition or i do not know ... i am lost :-) ???

                或者是否有其他与打字稿2.5.3"兼容的多边形填充的替代品???我想避免分叉和重写类型.

                Or is there alternative for other poly fill that is compatible with typescript "2.5.3"??? I would like avoid to fork and rewrite typings.

                非常感谢您的帮助

                推荐答案

                这个问题的简单答案是你不需要为 fetch 添加类型,因为 TypeScript 现在已经在 lib.d.ts 文件中了.

                The simple answer on this one is that you don't need to add types for fetch, as TypeScript has them in the lib.d.ts file now.

                因此,如果您删除 @types/whatwg-fetch 开发依赖项,您的程序应该可以编译.

                So if you remove the @types/whatwg-fetch development dependency, your program should compile.

                这通常是您在定义文件中出现错误的确切原因,尤其是基于新兴标准的任何内容.

                This is very often the exact reason you get errors in a definition file, especially with anything based on emerging standards.
