I'm trying to follow the quickstart on running Angular locally (on MacOS 10.13.6). With the first command, I already get some errors:

npm install -g @angular/cli

Output:

Running with sudo gives me the following:

My node version is LTS (10.15.3). Any idea what's causing this and how to get angular to run on Mac?

    I literally had this issue yesterday. The node-pre-gyp erros is realted to that npm package that isn't hasnt been fully working for macs. Apps will work fine just be patient for the updated package to come out. – Patricio Vargas Mar 13 '19 at 04:45

you will need the write permission in node_modules directory:

sudo chown -R $(whoami) ~/.npm

Running sudo when installing npm will give you problems in the long run, so just run the command above.

npm throws error without sudo

sudo npm install -g @angular/cli

run with sudo permission and you should be good.

the /usr/local folder needs root permission, please try install it with sudo :

sudo npm install -g @angular/cli

    using sudo isn't good practice. then it will ask you to use sudo every time you install a package. I ran into this issue yesterday – Patricio Vargas Mar 13 '19 at 04:42

As mentioned in the comments, using sudo isn't good practice, I had to run the following 3 commands to gain ownership of the relevant directories:

sudo chown -R $(whoami) ~/.npm  
sudo chown -R $(whoami) /usr/local/lib/node_modules
sudo chown -R $(whoami) /usr/local/bin

Now I can install Angular CLI (or any other node packages) globally, without the need for sudo.
