Answer 1

You will need to remove package-lock.json, .npm and node_modules folder.

Required steps:

npm install npm@latest -g
npm cache clean — force
rm -rf ~/.npm
rm -rf node_modules
rm -f package-lock.json

In npm install .staging issue, When you run npm install, it creates the node_modules folder but all the modules go into a subfolder called .staging

Answer 2

I have found the same issue when I started a project in my linux machine and I like to clone to work on it from a Mac.

Solution working for me:

npm install --no-optional

The other way to solve this, is to remove the package-lock.json.
