I have found that updating /usr/lib/node_modules/myth/node_modules/clone-component/index.js:30:17 to use Object.prototype.hasOwnProperty.call(obj, key) fixes the issue.

component/clone has an update to 0.2.3 which seems to address this issue.

Hi guys,
I'm also experiencing this issue - 'obj.hasOwnProperty is not a function' - because of my node version I believe. But I can't resolve it.

I love myth but I'm having an issue after changing my dev setup. I've moved from working directly on a dev server to local machine so I've different node setups. Myth is working fine on the dev server.

Local - http://take.ms/fbyqm - has node 6
Dev Server - http://take.ms/6PO2T - has node 0.10

I've found there is a pull request on Github - #143 - but I'm unable to resolve the local issue even after updating the .travis.yml with the node version.

I appreciate that Myth is not fully supported but it'd be a shame to not resolve it. I prefer it to the preprocessors.

Thanks,

Ian.

I've done a bit of research into this, and component/clone on Github is @ 0.2.3 (which fixes the issue), while clone-component on npmjs.com is still only @ 0.2.2.

I have emailed the developer asking to update, but have gotten no reply.

Hello,

I just published my fork on npm to have a myth version working with node 6
