I am new to typescript. As I was following a video tutorial of using a request api. I used following command to install request library:
npm install request --save
then, in order to use auto-complete in visual studio code editor for typescript, I tried installing type definition for request:
npm install @types/request --save-dev
But I got this below error while doing so:
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
I even followed this link : https://www.npmjs.com/package/@types/request
the video tutorial that I was following was : this
NOTE : I am facing this problem in my windows 7 laptop. When I tried the same steps in other laptop with windows 10, all commands run smoothly. No error.
kindly tell me what can I do next in order to continue doing practice and learning on this REQUEST topic.
