New project fails to npm install #19

I was just following the instructions at

gatsby new some-blog https://github.com/gatsbyjs/gatsby-starter-wordpress-blog

But npm fails to install with

Changed react-helmet version from 5.2.1 to 6.1.0 (latest) in package.json fixes the npm install issue. Not sure if it is fully backwards compatible with v5.

I have a similar problem – after following the guide there's a bunch of npm errors shown, and running gatsby develop gets stuck. Looks like this project is abandoned or something... I've tried different methods of adding gatsby-source-wordpress (from scratch, from a starter) and it all fails or gets stuck. How can this be advertised as "working" when it's not?

hello @Asgaroth, in order to make it work you need to do two things, after you run that command:

  1. Go into directory "some-blog" and in the package.json reduce react and react-dom to 16.0.1
  2. Run npm install "npm i acorn --dev"

After that, check with "npm run start" or "yarn start" to spin up the local server.

Alternatively, you can run npm install --legacy-peer-deps to leave the React versions as they are in this repo. That's what I did, and it installed everything successfully.
