  <p>I look at the log file and I see its trying to fetch the package from a location that doesn't exist. Not sure from where it gets pulled. How do I fix this location path and install angular cli. Same happens when I try to install typescript or any other npm package. all of them try to install from the location mentioned below and it fails with 404</p>
