当我尝试使用npm我安装我的项目包时出现错误

Question

I was getting error installing expressJs to my packages. I have had to do an npm cache clean --force no sucess, then I deleted my node_modules and package-lock.json , I try to reinstall packages using npm i I still got an error.

Now I deleted node.js from my pc windows 10 and downloaded and installed the latest node and tried to reinstall the project packages again. Now the error I get is this

$ npm i
npm ERR! Unexpected end of JSON input while parsing near '...ncies":{"autoprefixer'

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\Chioma Onyepere\AppData\Roaming\npm-cache\_logs\2019-05-28T20_26_29_676Z-debug.log

I had to delete all of npm-cache directly from my windows 10 pc, from %AppData%, ie ~/AppData\\Roaming\\npm-cache . Everything works fine now.
