    I updated node from v4.0.0 to v6.2.2 and updated npm from version 2.14.2 to 3.9.5 (current versions),
    deleted the node_modules from my project then did npm install followed by ng init, I was asked if I wanted to overwrite package.json, system-config.ts and a bunch of others which I said yes to all and I was able to get running again. I did lose anything I had added Bootstrap, Sass etc. Thank goodness for source control. I manually merged my changes back in. Everything worked except for the routing. I followed the Dev guide for the new router stuff and finally got that working.

    generating routes is disabled, hopefully they get that fixed soon

    Doing an extra npm install worked for me.

    ng new PROJECT_NAME
    cd PROJECT_NAME
    ng serve
    exists-sync failure

    npm install
    ng serve
    success

    I just uninstalled node and npm and reinstalled on versions:

    • node v6.2.2
    • npm to 3.10.2

    Same error displayed

    Fixed that by going to 'node_modules/angular-cli' inside project and run 'npm install'
    then run ng serve again.
