typescript - 无法在打字稿中安装请求类型定义
问题描述
我是新手typescript。正如我正在关注使用request api. 我使用以下命令安装请求库：
npm install request --save
然后，为了在 Visual Studio 代码编辑器中为打字稿使用自动完成功能，我尝试为请求安装类型定义：
npm install @types/request --save-dev
但是这样做时我得到了以下错误：
npm ERR! Unexpected end of JSON input while parsing near '...57","dependencies":{}'
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\ABC\AppData\Roaming\npm-cache\_logs\2020-02-05T09_09_06_453Z-debug.log
我什至关注了这个链接：https ://www.npmjs.com/package/@types/request
我正在关注的视频教程是：this
注意：我在 Windows 7 笔记本电脑中遇到了这个问题。当我在其他装有 Windows 10 的笔记本电脑上尝试相同的步骤时，所有命令都运行顺利。没有错误。
请告诉我下一步该怎么做才能继续练习和学习这个REQUEST主题。
