javascript - Node.js always gives errors when using -g flag -
whenever try installing node globally, bunch of errors. tried in powershell , didn't throw errors, might because it's powershell , not official node command line application that's installed. tried powershell because thought might able copy , paste errors, can't/they didn't appear. tried again in official node console, , got errors again. there's screenshot of errors @ bottom.
here's npm-debug.log file generated when tried npm install learnyounode -g:
