Try the following:

step 0: run this command

npm uninstall -g @angular/cli npm cache clean 

step 1: delete this folder: C:\Users\%YOUR-USERNAME%\AppData\Roaming\npm

step 2: uninstall Nodejs from Windows

step 3: restart your PC

step 4: install a fresh copy of Nodejs from here:

step 5: install the CLI globally

npm install -g @angular/cli@latest 

try this :

$ npm remove -g angular-cli $ npm cache clean $ npm install -g angular-cli 

Check the path(npm -v, node -v)ie for Setting Path variable

User Variable C:\Users\Username\AppData\Roaming\npm System Variable C:\Program Files\nodejs 

Restart System & update,clean npm

npm install npm@latest -g npm cache clean 

Uninstall prev angular cli and then install angular cli again

npm uninstall -g angular-cli npm install -g @angular/cli 

I had this problem recently running on a Windows box.

To solve: using gitbash:

npm uninstall -g @angular/cli npm cache verify 

uninstall node using the uninstall option on the Windows menu > Node using gitbash: cd ~/AppData/Roaming rm -rf npm rm -rf npm-cache

RESTART WINDOWS : You must restart windows

reinstall node.js

npm i @angular/cli -g 

That worked.

1. Delete c:/users/{accountname}/AppData/Roaming/npm/node_modules/@angular
2. Delete c:/users/{accountname}/AppData/Roaming/npm/ng
3. Delete c:/users/{accountname}/AppData/Roaming/npm/ng.cmd
4. Delete c:/users/{accountname}/AppData/Roaming/npm/ng.ps1
5. run this command in cmd

npm install -g @angular/cli
