Running a Gatsby App from node_modules - "Generating SSR bundle failed"

Hello everyone!

I think I already read the relevant issues but I don’t think they are the same problem.

What I’m trying to do is to run a Gatsby app that I’ve published to NPM from another project, that is after installing it. The idea is to build a generic Gatsby app and overwrite some components from the root project.

However I cannot even start a fresh Gatsby app from the node_modules by using this script: cd ./node_modules/mygatsbyapp && yarn start

The error that is thrown is:

 ERROR #98123  WEBPACK

Generating SSR bundle failed

Unexpected token (31:4)

File: .cache/develop-static-entry.js:31:4

The line that causes the error has this code: <meta key="environment" name="note" content="environment=development" />

The same project runs fine when I run it as a normal project (cd mygatsbyapp && yarn start)

EDIT: This is my gatsby info output:

@puzzledbytheweb Gatsby Themes is exactly what I was looking for! Can’t believe I haven’t came across them yet. Thanks a lot for your response.
