Broccoli Plugin failed: block-scoped declarations not yet supported outside strict mode

[eelke]

I have updated NPM, Updated ember-cli to 2.14.0 following the release note instructions.

I have then created a new Glimmer project, following the glimmer instructions, and then try to start the server, which fails due to some strict mode error:

$ ember new afk-subsidiewijzer -b @glimmer/blueprint

cleaning up...

Not sure if it helps, but you can try adding IE 11 to config/targets.js.

[twokul]

@eelke could you run ember --version --verbose and paste the output?

[eelke]

@Cryrivers That did not fix it @twokul Sure, see below

ember-cli: 2.14.0
http_parser: 2.7.0
node: 4.7.2
v8: 4.5.103.43
uv: 1.9.1
zlib: 1.2.8
ares: 1.10.1-DEV
icu: 56.1
modules: 46
openssl: 1.0.2j
os: darwin x64

@eelke try bumping your version of node.js to anything 4.8+, ideally to 7+ if you can

[eelke]

I have switched over to Node 7.10.1 (current v7 version) and now the server works fine. Thank you @twokul. I will close the issue, but want to point out that the Glimmer.js documentation currently states: Ember requires Node.js 4 or higher and npm 2.14.2 or higher.. That might need an update?

[twokul]

@eelke yes, Good Sir, I believe you are correct. Thanks for flagging this!
