error running example

[jamesyoung]

Hi,

I'm trying to run the example and getting the following error after pulling the repo and doing : 'npm install'

npm ERR! peerinvalid The package loopback-datasource-juggler does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer loopback@2.0.0-beta3 wants loopback-datasource-juggler@2.0.0-beta1
npm ERR! peerinvalid Peer loopback-connector-mongodb@1.2.6 wants loopback-datasource-juggler@1.x.x

npm ERR! System Darwin 13.2.0

npm ERR! node -v v0.10.28
npm ERR! npm -v 1.4.9
npm ERR! code EPEERINVALID

What do I need to do to get the full stack example running? Any help much appreciated. Thanks.

loopback-connector-mongodb is not compatible with loopback 2.x.

Temporary workaround:

• remove loopback-connector-mongodb from package.json dependencies
• rm -rf node_modules/loopback-connector-mongodb
• npm install

The example uses memory connector by default, so it should work fine in dev environment.

thanks bajtos, I'm able to start the example app. This is what it looks like : http://screencast.com/t/ILWUT3rMkEJ

I am not able to register or login.

Below is my terminal output :

What am I doing wrong?

[bajtos]

I am able to reproduce the problem on my machine. This is the important line:

[gulp] 'build' errored after 1.16 s ENOENT, open '/Users/bajtos/src/loopback/example-full-stack/html5/build/datasources.js'

[bajtos]

Workaround: create html5/build directory before running gulp for the first time.

I have submitted a fix, see the pull request link above.

[jamesyoung]

Did that, now getting a different error :

$ gulp
[gulp] Using gulpfile ~/loopback/loopback-example-full-stack/gulpfile.js
[gulp] Starting 'build'...
[gulp] 'build' errored after 1.28 s Object function RemoteObjects(options) {
EventEmitter.call(this, {wildcard: true});
// Avoid warning: possible EventEmitter memory leak detected
this.setMaxListeners(16);
this.options = options || {};
this.exports = this.options.exports || {};
this._classes = {};
} has no method 'convert'

[bajtos]

See strongloop/strong-remoting#69. Hopefully the fixed version will be available soon.

For now, you can downgrade strong-remoting to 1.4.1 in ~/loopback/loopback-example-full-stack/node_modules/loopback.

Sorry for making your initial experience so painful, I am glad you have persisted so far. Hopefully this is the last issue you'll encounter :)

@bajtos - looking at my ~/loopback/loopback-example-full-stack/node_modules/loopback/package.json file, strong-remoting dependency is "~1.4.0". This is what you meant? I changed it anyway to ~1.4.1 and still getting the same error. Thanks for the continued help.

[ritch]

@jamesyoung @bajtos I just released strong-remoting 1.4.3 which fixes this issue

[jamesyoung]

thanks @ritch - updating to strong-remoting@1.4.3 fixed that error. I am not getting a different error when trying to run http://localhost:3000

This is the important message:

Error: Failed to lookup view "home.ejs" in views directory "/Users/jamesy/loopback/loopback-example-full-stack/views"

The problem was introduced by my PR #10, I can reproduce the problem. The previous revision (d35e5a3) works on my machine.
