NPM fails with the code: npm ERR! code ELIFECYCLE - node.js

Question

I am fairly new to node and javascript. I am trying to run this on my localhost
https://github.com/bitpay/wallet
originally I was using node.js v14 but I was getting an error. I did some research and found that I should downgrade to node.js v11.
After doing so I get an error after trying to run npm install.
'rm' is not recognized as an internal or external command,
operable program or batch file.

I'm not sure exactly what to do to fix this. I've read other posts and tried to do what they suggest. I deleted the node_modules file and clear the cache but I am still getting the same error. I've noticed it's saying 'rm' is not recognized as an internal or external command. I've tried to change it to del instead of rm but that doesn't seem to help either. Any suggestions on how to get this to work on my localhost?

Answer 1

this is the first line from the log your shared indicating what is the error
'rm' is not recognized as an internal or external command,
it happens since (as you mentioned) you are running windows and i assume you are running npm under cmd or powershell, which does not have rm command natively.
i would suggest your to switch to windows subsystem for linux, which should have system command like rm and see whether it solves your issue.
