title: Problem with the command "npm install fs"
body: <p>I am not used to work with Linux, so maybe this is a silly question. In the lab that I am working on, I am asked to run the command "npm install fs" to read/write files.</p>
  
  <p>But here is the error that i have and I don't know how to solve it, i couldn't find similar problems too.</p>
  
  <p>PS: I am working on Ubuntu 17.10.</p>
