jQuery missing as dependency
In addition to #7, installing with npm doesn't fetch jQuery. This will cause the examples to fail, since they expect jQuery to be in the same directory as the other dependencies. Maybe this could be related to the AngularJS error in #5?
I'm not sure if it's related to your issue but I have pushed a npm fix in v1.3.1. The examples in the angular-split-pane repo are using bower. I npm example can be found here https://github.com/shagstrom/angular-split-pane-npm-example .
That one has a different issue. The fetched dependencies are put in
node_modules/@shagstrom/angular-split-pane/node_modules instead of
node_modules where the html file expects them. I'm using npm 2.15.8.
The workaround I did to fix the original issue was simply adding jquery as a dependency in the base package.json.
Try upgrading to npm >= 3.4
