What's your powershell version? (Not sure it'll help, but it help)

actually i figured out the issue The issue is in the powershell which npm is using by default even if you try to install nodemon from command prompt you get the same error because npm in the background is using powershell inside cmd too

so i changed the default shell used by npm to command prompt using - "npm config set script-shell cmd" and then the installation works after the installation gets complete i reverb back to the default powershell using - "npm config set script-shell powershell"

For those who are having the same issue i have attached a list of commands in the picture (refer to that and hopefully your issue gets fixed) also remy , if it can be fixed then try to fix it please ( if you want to generate this error put your command shell to powershell and then try to install it ) powershell version i am using is - 5.1.19041.1645
