I got the same error while building a MEAN stack application, I was installing firebase and firebase-admin under same folder(single package.json).

Finally, I found the solution here

Basically you need to use webpack-node-externals to exclude node_modules folder

1).npm install webpack-node-externals --save-dev

2).In your webpack.config.js

var nodeExternals = require('webpack-node-externals');
...
module.exports = {
    ...
    target: 'node', // in order to ignore built-in modules like path, fs, etc.
    externals: [nodeExternals()], // in order to ignore all modules in node_modules folder
    ...
};

Admin SDK cannot be deployed on client-side web frameworks like Angular. It can only be used in trusted server-side environments. See https://medium.com/@hiranya911/firebase-the-server-side-story-1f89064e9c16 for some additional details.
