I faced the same error recently. Here's how you can fix it

  1. Delete package-lock.json
  2. Goto gatsby folder path and run gatsby develop or run npm i

If it doesn't work, delete node modules and try the above steps again

It's quite self-explanatory.

You have installed a Gatsby version ^3.11.1 as it is extracted from:

npm ERR!   gatsby@"^3.11.1" from the root project

While gatsby-plugin-react-helmet as is, without a specific version tries to install the latest one (5.4.0). This latest version requires a Gatbsby version 4 onwards (major update) as it is extracted from:

npm ERR! peer gatsby@"^4.0.0-next" from [email protected]
npm ERR! node_modules/gatsby-plugin-react-helmet
npm ERR!   gatsby-plugin-react-helmet@"*" from the root project

That said, depending on your specifications you have two options:

The second one will have a lower impact in your project but ideally, sooner or later you will need to upgrade the Gatsby version.

I guess, being a lower major update any version 4 of the gatsby-plugin-react-helmet plugin should work. If not, try lowering the version.

Remember to clean the cache (with gatsby clean) in each trial.
