[jiverson]

May want to check out #6800

[ddimaria]

Agreed, check out: https://docs.npmjs.com/getting-started/fixing-npm-permissions

[Brocco]

Closing as a duplicate of #6800.

[thanhtung90]

I run chown it's worked
sudo chown -r XXX /usr/lib/node_modules/ or sudo chown -r XXX /usr/lib/node_modules/@angular/
if not it might chgrp
sudo chgrp -r XXX /usr/lib/node_modules/

[d668]

sudo npm install -g --unsafe-perm --verbose @angular/cli

[pushkalb123]

Run following commands
npm i -g npm-check-updates
npm-check-updates -u
npm install

[WuglyakBolgoink]

@pushkalb123

and you see in log:

try this install first node-gyp
sudo npm install node-gyp -g

sudo npm install -g -f @angular/cli@latest

[SatishMHiremath]

I have faced and fixed this issue relates node-sass and python error.Try installing latest angular cli command with the steps below

Set the system variable path as well:
C:\Users\windowsusername\AppData\Roaming\npm

C:\Users\windowsusername\AppData\Roaming\npm\node_modules@angular\cli\bin;

C:\Program Files\nodejs;

Then start using angular cli command prompt using:
angular client project folder path>npm install -g @latest

angular client project folder path>npm install -g node-gyp
