Problems installing 0.12.x with handlebars templates

[yankeeinlondon]

I am new to sails and so I started by installing 0.11.1 with handlebars as the templating engine:

 npm install -g [email protected]
 npm install -g sails-generate-views-handlebars
 # create repo
 sails new sailor --template=handlebars
 npm install --save handlebars
 npm install --save consolidate

Worked like a charm but then I realised that the hook for Swagger only worked with 0.12 and possibly only with the code on master. So I then preceeded to walk a little closer to the bleeding edge with:

npm uninstall -g sails
npm install -g git://github.com/balderdashy/sails
# ...

This didn't go so well. Tons of errors on the install. Here's a small clipping:

In file included from ../src/bufferutil.cc:16:
../node_modules/nan/nan.h:261:25: error: redefinition of '_NanEnsureLocal'

If I had to guess it may have something to do with me using node 4.0.0 but this did work just fine with Sails 0.11.1. After a cascade of errors, however, it does install. I then create two new projects:

sails new foo
sails new bar --template=handlebars

Lifting foo appears to work (in this bare bones example) but lifting bar gives the following error:

Note: on reinstalling 0.11.1 I realise that the compilation errors I was referring to were present in this build too. I suspect -- just guessing -- this is node 4.0.0 related but that its ultimately inconsequential. The key difference though is that handlebars based services work in 0.11.x.

Thanks for the heads up @ksnyde. Just to make sure we're on the same page: the handlebars generators are community-supported features that won't be officially sponsored by development hours from our core team for Sails v1.0 (however runtime support for consolidate-compatible view engines like Handlebars will). We're working on Node 4 support and should have a patch soon :)

[yankeeinlondon]

Thanks @mikermcneil, sorry for the noob question but are you saying the issue above is likely to be resultant of template generation not doing something correctly (versus a runtime processing issue)? If that's the case, where is the best place for me to submit this type of issue?

[mikermcneil]

It looks like this is an issue with Node 4 / express-handlebars. Would you try this again with the latest version of Sails?

[tjwebb]

@mikermcneil I don't think that a 0.12 series of Sails has been published with the node 4 fixes yet. Has it?
