Cannot read property 'ember-bootstrap' of undefined

[GCorbel]

In and Ember 2.7 app, at this line I have this error :

Cannot read property 'ember-bootstrap' of undefined

If I do app = app.app it workes. I'm not working on an addon and the if statement is not true.

I don't know what's the definitive solution. What you think?

I have no idea, but ember-bootstrap has a lot of tests that also run for ember 2.7, so really there should be no problem in general. I think there must be something with your particular app. I just recently set up a fresh app with ember-cli 2.7 / ember 2.7 without any problems, so the problem must lie somewhere else unfortunately!

@simonihmig I tried to contribute to this addon and I have the problem. I don't see anything special. Please, can you check it?

[GCorbel]

Sorry, I was wrong. Your addon seems to be correct. Thanks.

I finally found a way to reproduce the bug. I when ember-bootstrap is an dependency of an addon. For example, a package with this in package.json :

{
  ...
  "dependencies": {
    "ember-cli-babel": "^5.1.3",
    "ember-bootstrap": "0.10.0"
  }
  ...
}

And I have this stack trace :

I don't understand why it do that... can you help me?

@GCorbel Same here: I have an addon that includes ember-bootstrap as its dependency. When I install the addon into another app, I have this error.

[srvance]

@viniciussbs @GCorbel Can you share the addons that include ember-bootstrap with us?

Can you tell us what versions of ember, ember-cli, and ember-bootstrap you're using?

[viniciussbs]

@srvance It's my own private addon with core UI componentes shared with other apps.

$ ember -v
ember-cli: 2.11.0

"ember-bootstrap": "0.11.1"

One of the apps already have ember-bootstrap (same version) into "devDependencies" as its own dependency.

[Charizard]

Same here. My case exactly is similar to @viniciussbs

[srvance]

Any chance you can upgrade to the latest? We're not making changes to the 0.* versions, and there have been several changes to how the hosting app is identified.

We know that there are some issues with ember-bootstrap as an addon dependency, at least one of which is that ember-cli doesn't have a story for running blueprints of addon dependencies.

It would probably be better to make it a peer dependency if you can and to have your addon's blueprint validate that it's present.

@srvance I did point to master and it worked like charm. Thanks 🌮
