Strange jQuery requirements

[forgotten8]

After installing and including meteor/svelte:blaze-integration I kept on getting the error below.

The only way I could resolve this was by adding jQuery to both the NPM and Meteor Package Manager. ie

> meteor add jquery (v3.0.0)
> meteor npm install jquery --save  (v3.6.0)

Without both packages installed - it produced the errors below.

I tested by only installed npm [email protected] [email protected] - nothing helped.

Uncaught Error: jQuery not found
