Tried to install latest Angular (10 in this case) the other day only to bump into this error:
$ npm install -g @angular/cli

Obviously permission error. Culprit appears to be current installation of Node.js with sudo:
sudo apt install nodejs
Fiddling around with user permissions won’t do much good and might do more harm in future. Easiest way appears to be reinstalling Node.js without sudo or installing new version of Node.js also without sudo.

Node Version Manager – nvm did the trick for Node.js:
Follow install instructions for nvm:
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bash
Open new terminal or follow instructions from script (export NVM_DIR=...).
Install latest Node.js:
$ nvm install node
Downloading and installing node v15.0.1…
…
Now using node v15.0.1 (npm v7.0.3)
Creating default alias: default -> node (-> v15.0.1)
Check installation:
$ node -v
v15.0.1
Install latest Angular:
$ npm install -g @angular/cli
Check installation:
$ which ng
/home/user/.nvm/versions/node/v15.0.1/bin/ng
$ ng --version

That’s it. Just remember to avoid sudo while installing Node.js and npm packages.
