Cannot install angular-cli

Question

On my Mac, ng serve returns -bash: ng: command not found, so it seems that i need to install angular-cli. But sudo npm install -g angular-cli returns the follows.

Does anyone know what's wrong?

Answer 1

npm i -g @angular/cli

The error is written in the first line itself.

• sagars01: Hey you're getting permission denied error, please check you permissions if that's a company managed MAC.

Answer 2

based on docs Change npm's Default Directory

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, it will be a hidden directory on your home folder.

Make a directory for global installations:

 mkdir ~/.npm-global

Configure npm to use the new directory path:

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

Open or create a ~/.profile file and add this line:

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

Back on the command line, update your system variables:

source ~/.profile

Test: Download a package globally without using sudo.

npm install -g jshint

Instead of steps 2-4, you can use the corresponding ENV variable (e.g. if you don't want to modify ~/.profile):

NPM_CONFIG_PREFIX=~/.npm-global

Answer 3

I think you have a permission issue in the error logs:

gyp ERR! stack Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/@angular/cli/node_modules/node-sass/build'

Take a look what user/group and type of access have the /usr/local/lib/ and the /usr/local/lib/node_modules/ folders.

Change it according to what you need, worst case scenario if it's local development environment you can set it to 777 just to make sure that it's a permission issue:

sudo chmod 777 /usr/local/lib/node_modules/

I hope it works.
