yo ionic throws an error

[sineo]

Everytime I run "yo ionic", it keeps failing. I've updated node and npm and reinstalled yo and grunt and bower, but still get the error below:

Installing selected Cordova plugins, please wait. Installing starter template. Please wait

@sineo Same issue here.

The function this.engine is not defined. I ran into this while trying to update the version of some dependencies (like angular 1.4, cordova 5.1 and ionic 1.0.0)...

After digging around some, I've discovered that yeoman-generator 0.20.* does not work, but version 0.19.2 does. This is the culprit, as best I can tell:

https://github.com/yeoman/generator/commit/c094740fb8d9d18f1a9dcc1f2a78e153f0f9bb18#diff-661285f2c7d866fb08559eb1e5748a7f

See also the comments below that commit...

Anyway, the line 185 in generator-ionic/app/index.js which calls the now missing engine templating function wants to read an index.html file depending on which starter setup (sidebar, tabs, blank) you chose. This is an external resource from the guys at driftyco, so it seems unlikely there's any real templating to be done there?

Long story short: the following replacement of line 185 makes things work for me with the latest yeoman-generator, 0.20.1.

// this.indexFile = this.engine(this.read(path.join(this.starterCache, 'index.html')), this);
this.indexFile = this.fs.read(path.join(this.starterCache, 'index.html'));
