angular cli ng commands not working - npm

Question

Windows server 2012 R2
node v4.7.4
npm v4.3.0
I cannot do a "ng serve": "/c/Users//AppData/Roaming/npm/ng: No such file or directory"
I also cannot do "npm start": "Unexpected token {" then a huge call stack.
I have tried using various versions of node/npm/cli etc... I can't get anywhere.
my app's project.json file:

For what it's worth on my OSX machine, I am able to do npm start just fine:
Here are the version on my OSX:
ng -v gives me:
angular-cli: 1.0.0-beta.16
node: 6.9.4
os: darwin x64
npm -v gives me:
3.10.10

Answer 1

Try to upgrade your cli version there are lots of changes happened after beta16. You can do it like this;
npm uninstall -g angular-cli #angular/cli
npm cache clean
npm install -g #angular/cli#latest

Answer 2

Upgrade node and angular-cli
sudo npm install -g n
sudo n latest
sudo npm install -g #angular/cli

Answer 3

If you are on Mac, on the terminal; don't add the '--'. just type [ng version].

Answer 4

Solution:
update .npmrc file at C:\Users\{USERNAME}
with the below line
prefix=${APPDATA}\npm

Answer 5

Have you installed angular globally as Administrator? Then run ng commands as Administrator too.
