Question

the commands 'npm install' gives me the following error:

As can be seen from the error messages, npm install fails at nodemon#1.18.9 postinstall script.
I've tried things like, deleting the node_modules folder and re-running the 'npm install' command again, the same error appears.
Also, i tried cleaning the npm cache as suggested by this answer, and it didn't work. Trying to separtely install nodemon gives the same error as above.

Answer 1

I have the same problem while I installing
nodemon
in devDependencies for my existing projects in different computer.
I do a research and found a solution that helped me to solved this kind for problem. It's happening because of security issues depending on your OS.
Solve this by :
npm install -g nodemon --unsafe-perm=true --allow-root
PS :
This too can happen in Electron also, so u can solve by -
npm install -g electron --unsafe-perm=true --allow-root
