问题
I am new to npm and Angular 2, I am trying to setup a new Angular 2 project using angular/cli.
I am currently running:
Node v8.9.3 npm v5.6.0 Windows 10
First, I ran npm install -g @angular/cli which seemed to install just fine. Then I went to the folder where I wanted to start my project, ran ng new my-app but kept getting this error.

回答1:
From the command line run
ng -v
This should output 1.6.0. If it doesn't you have an older version of the CLI installed.
Run:
npm cache --force clean
And then:
npm install @angular/cli -g
If that doesnt work remove the folders in C:\Users\<username>\AppData\Roaming
回答2:
Use these lines:
npm cache clean --force
npm install -g @angular/cli@latest

After lots of research on this I came to a final solution, I tried lots of solutions but not worked for me. Try this it works for me, I'm using Ubuntu.
Uninstall angular cli.
Hit following command,
sudo npm uninstall -g angular-cli
check version if version still present, check path
which ng
It will give following output
/usr/bin/ng
Now delete this by using
sudo rm -rf /usr/bin/ng
then remove angular package
sudo rm -rf /usr/lib/node_modules/@angular
Now your angular cli is completely removed from your machine.
Now check angulars latest stable version and install it.
if problem is still present than uninstall node and delete global node_modules folder.
sudo apt-get purge nodejs
sudo apt-get autoremove
sudo rm -rf /usr/lib/node_modules
And install node and angular again.
And try to create new project. Hope it will work for you. Thank You!
