brunch build --production fails only in production - node.js

Question

Out of the blue build script started to fail. No changes in environment or configs at all. Works fine in dev, fails in prod.
Both dev and prod (both Ubuntus):
$ npm -v
5.3.0
$ node -v
v6.11.2
In dev:
oleg#DevVM ~/Code/loaded.bike/assets $ npm run deploy
> # deploy /home/oleg/Code/loaded.bike/assets
> brunch build --production
17:49:59 - info: compiling
17:49:59 - info: compiled 19 files into 2 files, copied 32 in 6.9 sec
In prod:
deploy#loaded-bike-app:~/builds/assets$ npm run deploy
> # deploy /home/deploy/builds/assets
> brunch build --production
00:45:30 - error: Initialization error - Could not load global module 'jquery'. Possible solution: add 'jquery' to package.json and `npm install`. Could not load global module 'jquery'. Possible solution: add 'jquery' to package.json and `npm install`.

Adding jquery, tether to package.json fixes require error but then it just chokes on sass compile. Is this just JS missfiring async function out of order or what is going here? Once again, it started to fail completely out of the blue. Deployed just fine yesterday and today if fails without me changing anything. Any clue what might be wrong here?
EDIT:
package.json:
{
"repository": {},
"license": "MIT",
"scripts": {
"deploy": "brunch build --production",
"watch": "brunch watch --stdin"
},
"dependencies": {
"bootstrap": "^4.0.0-alpha.6",
"phoenix": "file:../deps/phoenix",
"phoenix_html": "file:../deps/phoenix_html"
},
"devDependencies": {
"babel-brunch": "6.0.6",
"brunch": "2.10.10",
"clean-css-brunch": "2.10.0",
"css-brunch": "2.10.0",
"sass-brunch": "2.10.4",
"uglify-js-brunch": "2.1.1"
}
}
I'm actually seeing this crap on prod (but not on dev)
npm ERR! peer dep missing: jquery#>=3.0.0, required by bootstrap#4.0.0-beta
npm ERR! peer dep missing: popper.js#^1.11.0, required by bootstrap#4.0.0-beta
What is that about? Bootstrap defines those as dependencies (not peerDependency) in its own package.json. npm doesn't pull in dependencies now?

Answer 1

"bootstrap": "^4.0.0-alpha.6"
Needed to lock the version. Bootstrap went from alpha.6 to beta yesterday. Messed everything up. No idea why is started to fail only on one machine (even after npm cache clear). Sass compile fails under beta, so I locked it to alpha.6 for now.
I think I need to start locking dependency versions. This took way too long to figure out.
