Meteor 2.3.1 Not Resolving an NPM Package? [SOLVED]

I installed Meteor 2.3.1 and on building the app I see:

Unable to resolve some modules:

  "@material-ui/core/styles/createMuiTheme" in
/Users/myUser/Documents/code/src/gitlab.com/myMeteorapp/imports/client/ui/router.jsx
(web.browser)

If you notice problems related to these missing modules, consider running:

  meteor npm install --save @material-ui/core

I’ve run meteor npm install --save @material-ui/core several times, and I do see @material-ui/core in my node_modules directory:

What am I missing?

It turns out it really wasn’t there – somewhere MUI updated createMuiTheme to createMuiStrictModeTheme. I found out just by looking in the @material-ui/core/styles/ folder. :slight_smile:
