Building Angular 2 application into "./www" directory.
/bin/sh: ng:command not found

This error would occur if you do not install angular-cli with root permission (that is fine, it just means you don’t have it systemwide)

This is a simple PATH problem, check your shell’s path export method

`$ export PATH=$PATH:$PWD/node_modules/.bin`

As a forewarning, we are moving the CLI npm package to "@angular/cli" with the next release,
which will only support Node 6.9 and greater. This package will be officially deprecated
shortly after.

To disable this warning use "ng set --global warnings.packageDeprecation=false".

You have to be inside an angular-cli project in order to use the build command.

Probably due to this commit, please check your angular cli version

ng --version
@angular/cli: 1.2.0
node: 8.1.3
os: linux x64

Note the first line, it shouldn’t be the legacy angular-cli: 1.0.0-beta
