Getting error with babel inside Gatsby

[nmn]

Everytime I try to do gatsby develop I get this error.

I've tried the two latest versions of gatsby with the same result.
I tried use the master from github, ran the build scripts, set published to true and then got the same result.

I guess this is connected to the other issue to upgrade to babel 6. But am I just missing something?

Are you trying to use Babel 6 with your site?

No, I just used Gatsby to generate and then gatsby develop

[KyleAMathews]

So you ran:

gatsby new test-gatsby-site
cd test-gatsby-site
gatsby develop

And then saw this error?

[tleunen]

This is the error I also get when I try to generate and test a gatsby site inside a project using Babel 6.
But I don't understand why there's a conflict between the parent Babel and the Babel used by gatsby.

The directory generated by gatsby has its own dependencies, its own babelrc file, so why is there a conflict?

[KyleAMathews]

It's beyond me why but that's how Babel works. As I understand it, Babel looks to parent directories (perhaps until it finds a .git directory?) for .babelrc. In any case, I've actually been working today on updating Gatsby to Babel 6 so this should be fixed soon.

Just to double-check we understand the problem correctly — if you copy the Gatsby site to its own directory does it work then?

[KyleAMathews]

And here's the PR actually :) https://github.com/gatsbyjs/gatsby/pull/197/files

Want to also make Gatsby default to using the locally installed version of Gatsby so not going to merge and release this tonight but if you want to clone the PR and see if that gets you working, that'd be great.

[tleunen]

Yes @KyleAMathews, if it's in a complete different directory (or if the babelrc of the parent directory is removed), it works as expected.

I'll test it :)
