Surely haven't seen auch.

Q1: what js runtime you are using?

Q2: What version of this gem? If not latest (1.0.0), can you try also with that?

kikonen commented

Based into that error "Unrecognized node in FTL backend" I deduce that you might be using webkit based runtime. Anyway this sounds like but in javascript runtime, and possible fix is to try different runtime. Also version 1.0.0 of ngannotate-rails gem might reduce changes of this, since it's by default ignoring js files in "vendor" -assets paths.

tony-kerz commented

hi kari,

i was using default version which was currently pre-1.0.0, but when i specified 1.0.0, it worked 👍

as an aside, i'm not sure how to determine what js-runtime is in play, do kno how to do that?

anyway, thanks for the prompt response!

best,
tony.

kikonen commented

I believe Gemfile should indicate what js runtime is used.

kikonen commented

Currently used runtime should be shown via:

rails console
ExecJS.runtime

cool, thx k:

Hi there,

I have the same issue here. I switch to 1.0.0 and it's still happening.

here is my runtime :

2.2.1 :001 > ExecJS.runtime
 => #<ExecJS::ExternalRuntime:0x007fbde447f578 @name="JavaScriptCore", @command="/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc", @runner_path="/Users/christophe/.rvm/gems/ruby-2.2.1/gems/execjs-2.5.2/lib/execjs/support/jsc_runner.js", @encoding=nil, @deprecated=false, @binary="/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc", @popen_options={:internal_encoding=>#<Encoding:UTF-8>}>

Hope it can help ?

kikonen commented

Try setting explicitly in Gemfile different js runtime.

gem 'therubyracer',  platforms: :ruby
christophe-dufour commented

Sorry for the delay, but YES, it fix it 👍
