Run these commands in a terminal window:

sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/lib/node_modules
sudo chown -R $USER /usr/local/lib/node_modules

Same problem. I reinstalled the latest version of node via https://nodejs.org/en/download/ instead of using terminal. This resolved the issue.

If you're really blocked on installing NPM modules globally (e.g. on some corporate laptop), you could just install them all in a single local folder somewhere and then add the path to node_modules/.bin/ to your PATH environment.

I had this issue, I could fixed it by calling sudo on every global install. I wasn't ok with that.

I followed the n package installation advices to be able to install npm packages without sudo.

sudo chown -R $(whoami) /usr/local/bin /usr/local/lib /usr/local/include /usr/local/share

Answer of @jeduard didn't work for me.

I had a similar issue when trying to install React -- issues with permissions being denied.

This is where SUDO can come in handy, it allows a permitted user to execute a command as the superuser or another user. Think of like "Run as Administrator" on Windows. If you type in the following command, it should allow you to access all of the needed folders with the proper elevated access.

sudo chown -R $(whoami) /usr/local/bin /usr/local/lib /usr/local/include /usr/local/share

This is also denoted in Dimitri's answer: https://stackoverflow.com/a/60791736/3803726

Best way to solve your npm install -g issues:

https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

This way, you will never need to use SUDO or change permissions.

Quoting:

  1. Back up your computer.

  2. On the command line, in your home directory, create a directory for global installations:

    mkdir ~/.npm-global

  3. Configure npm to use the new directory path:

    npm config set prefix '~/.npm-global'

  4. In your preferred text editor, open or create a ~/.profile file and add this line:

    export PATH=~/.npm-global/bin:$PATH

  5. On the command line, update your system variables:

    source ~/.profile

Appending sudo before the npm install saved my day:

sudo npm install -g @angular/cli

Once you provide your system password, installation should finish smoothly:

I had the same issue.
type this cmd in terminal

sudo nautilus

after that, it opens another file manager that has root access

enter image description here

after that type

    sudo apt install nodejs
sudo apt install npm
sudo npm install -g npm@latest
sudo npm install -g @angular/cli
ng --version

For macOS try to run -

sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/local/lib/node_modules
sudo chown -R $USER /usr/local/bin/

If this still doesn't work you might need to add sudo to the npm install command.
