Installing @angular/cli from npm on Ubuntu Server

Question

I have an Ubuntu instance on AWS, I'm using forge to setup the server. I have installed the packages nodejs and npm. To solve the problem of installing global packages on Ubuntu I have followed the second solution mentioned in this tutorial, https://docs.npmjs.com/getting-started/fixing-npm-permissions

Now when I try to install using this command,

npm install -g @angular/cli

I get the following error,

forge@frontend-staging:~/frontend/current$ npm install -g @angular/cli

Answer 1

Run Following commands,

sudo apt-get uninstall nodejs

sudo apt-get install python-software-properties
$ curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -

sudo apt-get install nodejs

Now, check your node/npm version using

node -v 
npm -v 

Then try to install CLI.

Answer 2

We can use yarn package manager. Its fast, easy, understandable (meaningful). You can :

1. Install yarn

   npm install yarn -g

2. use yarn to install angular-cli

yarn global add angular-cli

Done thats its it worked for me.

Answer 3

I had a similar issue to this, the problem was caused by my version of node installer 4.7.2 and not newer 6.x version as per this question. So I installed angular-cli instead as this answer suggested.

If you have installed @angular/cli, you need NodeJS higher 6.9.7, together with NPM 3 or higher.

If you have installed angular-cli, you need NodeJS higher than 4.4.x, together with NPM 3 or higher.

For more see the links above and read the prerequisites.

Answer 4

You are getting this error because your configuration is "current: {"node":"4.2.6","npm":"3.5.2"}". As per the documentation, You need to have Node 6.9.0 or higher and NPM 3 or higher. For more information, Please visit Official Site: https://www.npmjs.com/package/@angular/cli.

What you need to do is, Update your node version. All d best!!!
