Method 1: Use sudo command

You can use sudo command to install any package with administrator permissions. To install any package with npm run the given command:

sudo npm install -g <package-name>

After running this command it may ask you to enter the password of your computer and after entering the password your package will install.

Method 2: Change the ownership

On the other side, we can change the `ownership` of the directory where npm is installed on your computer. To do that we can use the given command:

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

Method 3: Install packages locally

Try to install the npm package locally instead of globally. To install any package locally use the given command:

npm install <package-name>

Hope one of the solutions works for you ☑️.
