Run bower from root user, it's possible? How?

Question

I have a local development server where I test a lot of things, now I'm playing with bower to manage the libraries' dependencies in my Symfony2 project. After getting NodeJS (v0.10.31) installed and bower (1.3.9), I tried to run the command sp:bower:install which belongs to Symfony2 SpBowerBundle from console as root:

Symfony > sp:bower:install
Installing bower dependencies for "TemplateBundle" into "/var/www/html/tanane/src/Tanane/TemplateBundle/Resources/config/bower/../../public/components"

bower ESUDO         Cannot be run with sudo

Additional error details:
Since bower is a user command, there is no need to execute it with superuser permissions.
If you're having permission errors when using bower without sudo, please spend a few minutes learning more about how your system should work and make any necessary repairs.

You can however run a command with sudo using --allow-root option

I know that adding --allow-root works since I tested directly from bash but it apparently isn't allowed from the bundle command line. Now, is the only way to run bower as root to add --allow-root or does it exist another way ?

Answer 1

below answer is for symfony framework's bundle, but if you come here from google using phrase "bower root" you have two options to solve that:

1. add --allow-root to command
2. set global bower config that will allow running bower as root

Option 1: you can run bower as root by typing:

bower install --allow-root

root is allowed by setting --allow-root command parameter

Option 2: is using global setting that allows root, by creating file: /root/.bowerrc which have inside following configuration:

{ "allow_root": true }

how to do this in SpBowerBundle symfony bundle:
probably you haven't set sp_bower.allow_root to true in SpBowerBundle config

in bundle config, by default you have set something like this:

allow_root: false # optional

but you should have:

allow_root: true

so in app/config/config.yml add this bundle config

sp_bower:
    allow_root: false # optional
