Gatsby: After upgrading to version 1.9.264, site is blank and status code is 404

[domachine]

Description

I just upgraded gatsby from version 1.9.250 to 1.9.264. Before that upgrade my site was working fine in development mode. After the upgrade all pages yield blank output with a 404 as status code.

Steps to reproduce

1. gatsby new test
2. cd test; npm i gatsby@latest
3. npm run develop
4. Visit http://localhost:8000 in the browser

Expected result

A sample page.

Actual result

A blank page with HTTP status 404.

Environment

• Gatsby version (1.9.264):
• gatsby-cli version (1.1.52):
• Node.js version: v8.9.4
• Operating System: Mac OS X

File contents (if changed)

gatsby-config.js: N/A
package.json: N/A
gatsby-node.js: N/A
gatsby-browser.js: N/A
gatsby-ssr.js: N/A

I reverted https://github.com/gatsbyjs/gatsby/pull/4756 which was the source of these troubles. Sorry for the bother everyone! Thing are back to working.

@m-allanson @pieh @KyleAMathews The downgrade should work, build command also hosed like develop as Kyle suggests in https://github.com/gatsbyjs/gatsby/pull/4756#issuecomment-393637140

Will add a more complete report of my issue over there but https://github.com/GraphCMS/gatsby-graphcms-example/pull/72#issuecomment-393635255
has the gist with links.

@rdela reverted the PR causing the trouble so things are working again. Thanks for the detailed bug report!

Upgrading to Gatsby 1.9.266 with #4756 reverted solved the issue for me. https://github.com/rdela/gatsby-graphcms-rd/pull/60#issuecomment-393517264
