Error: Cannot find module 'react-dev-utils/ignoredFiles'

[jordyvandomselaar]

Hey there, I had decided to make a fork of this repo as to create my own default template that is scaffolded when running create-react-app, I've only changed things like app.js, and I've added the styled-component package. My version runs off the master branch. Is there a specific branch to use for this?

Is this a bug report?

(write your answer here)
yes.

Can you also reproduce the problem with npm 4.x?

Yes.

(Write your answer here.)
I've tried both npm 4 & npm 5, by running them, and by running yarn both times.

Which terms did you search for in User Guide?

(Write your answer here if relevant.)
ignoredfiles

Environment

1. node -v: 8.8.1
2. npm -v: 4.6.1
3. yarn --version (if you use Yarn): 1.2.1
4. npm ls react-scripts (if you haven’t ejected): (empty)

Then, specify:

1. Operating system: Mac OS High Sierra
2. Browser and version (if relevant):

Steps to Reproduce

(Write your steps here:)

1. Fork create-react-app
2. Make changes in the default project template
3. Use said template
4. Run yarn start.

Expected Behavior

(Write what you thought would happen.)

I'd expect it to run my app.

Actual Behavior

(Write what happened. Please add screenshots!)

I get the following error + stacktrace;

yarn start
yarn run v1.2.1
$ react-scripts start
module.js:515
    throw err;
    ^

[Timer]

These changes haven't been released yet, when you fork, you most likely want to reset to the last tagged version -- or publish version of all modules yourself.
