Error with installing a dependency eventmachine (1.0.9.1)
Sample Error:
$ vagrant plugin install landrush
Installing the 'landrush' plugin. This can take a few minutes...
Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:
An error occurred while installing eventmachine (1.0.9.1), and Bundler cannot continue.
Make sure that `gem install eventmachine -v '1.0.9.1'` succeeds before bundling.

Ran into an issue with 'npm install' in a Vagrant VM on VirtualBox.
Issue might be related to running 'npm install' from a shared filesystem.
Error is:

Ran into an issue where an ember.js app was mostly working on Safari/Chrome on iOS, but one of the actions was not firing on a div element. I couldn't find any errors in the javascript console (after connecting iPad to Mac and using the Safari Developer menu).
Finally figured out issue was the action was never firing...traced that down to learn there are issues with touch events on certain html elements.
An easy work around is to add:
style="cursor: pointer"
Example:
{{#each sortedFoos as |foo|}}
<div style="cursor: pointer" class="col-md-4 {{if (eq foo.id foo.bar.id) 'highlighted'}}" {{action 'selected' foo }}>
</div>
{{/each}}

Ran into a problem of "Uncaught TypeError: Cannot read property 'shouldSupercede' of undefined"
Turns out the issue was that my route had a dynamic segment and I forgot to pass in the parameter.
Further, this was a mistake on my part, that I was creating a 'new' route, didn't want the 'new' route to be dynamic.
I was calling something like {{#link-to "foo.bar.new"}} where foo.bar required a bar to passed to the route.
this.route('foo', function() {
this.route('bar', {
path: ':bar_id'
}, function() {
this.route('baz');
this.route('new');
});
});
Resolved the issue by changing the route from 'foo.bar.new' to 'foo.new' which would create the bar entry
this.route('foo', function() {
this.route('new'),
this.route('bar', {
path: ':bar_id'
}, function() {
this.route('baz');
});
});
