angular cli ng commands not working

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

Solution:

update .npmrc file at C:\Users\{USERNAME}

with the below line

prefix=${APPDATA}\npm
