Error installing Composer on Ubuntu

I am trying to install Composer on Ubuntu 14.04. I was able to install the prerequisites. When installing composer, I get the following error. How to fix it?

npm install -g composer-cli
npm WARN deprecated [email protected]: Use mz or fs-extra^3.0 with Promise Support
npm WARN deprecated [email protected]: This package is no longer supported. It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in.
npm WARN deprecated [email protected]: Use uuid module instead
npm WARN deprecated [email protected]: Jade has been renamed to pug, please install the latest version of pug instead of jade

So firstly you should not install Hyperledger Composer as 'root'. You need to read the docs here before you proceed https://hyperledger.github.io/composer/installing/development-tools.html

So fundamentally this is an npm issue (in that it causes problems for npm, when you npm install as 'root' or 'sudo' privileges for installing modules).

I suggest you create a non-root user in your Ubuntu system. Then log in as that user. Then install the pre-reqs using the supplied prereqs-ubuntu.sh script from the link above. Then follow the instructions, installing as your non-privileged user.

Normal route to fixing a non-root install npm issue, is one of these shown here https://docs.npmjs.com/getting-started/fixing-npm-permissions

When you install composer modules globally (eg. composer-cli) you should install using a designated, non-root user as mentioned. If there are issues (eg, on Ubuntu with permissions to write/update node directories located in system directories like /usr/local) - one solution (but see link earlier) is perform the npm install to a directory you have access to - rather than resort to root or superuser access, as this is not good practice. Here is what to do to set the npm prefix to a given directory, ...

"npm config set prefix /home/myuser/"

In this case, global binaries are placed in /home/myuser/bin which is in your PATH, and the modules are placed in /home/myuser/lib ...
