How do I install angular-cli on ubuntu 16,04?

Question

I'm facing an issue installing angular-cli locally. I'm on Ubuntu 16.04.2 LTS with following versions of node.js and npm:

node: v7.10.0 
npm: 3.10.10

I tried to install angluar-cli using the following command:

$npm install -g @angular/[email protected]

this worked fine and completed with following warnings:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: 
fsevents@^1.0.0 (node_modules/@angular/cli/node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform
    for [email protected]: wanted {"os":"darwin","arch":"any"} (current:
    {"os":"linux","arch":"x64"})

Now when I'm trying 'ng' command:

  module.js:472
   throw err;
   ^
   Error: Cannot find module 'abbrev'

Solution 1

Just do this on command line:

sudo npm uninstall -g @angular/cli
sudo npm cache verify
sudo npm install -g @angular/cli --unsafe-perm=true --allow-root

Found here:Error: EACCES: permission denied, mkdir...!

This fix the npm EACCES permission denied which brake the angular/cli install on ubuntu 17.04 for me.

Solution 2

npm install @angular/cli@latest

Will not install angular-cli globally but it works for user.

Solution 3

To install it globally, use

npm install -g @angular/cli

To install last version and globally, use

npm install -g @angular/cli@latest    

And if you are using Ubuntu 18.04, use

sudo npm install -g @angular/cli@latest
