Steps to Reproduce

(Write your steps here:)

My problem has already been documented clearly, but the ticket was closed with no workaround documented or described. I don't understand what I'm supposed to do.

#5669

Expected Behavior

I did not expect an error message. I did expect to be able to continue to work on my app without reorganizing my project to remove the extra node_modules directory.

Actual Behavior

$ npm start

fbiba@0.1.0 start /path/to/my/project
react-scripts start

We detected TypeScript in your project (subdirectory/subdirectory/node_modules/array-flatten/array-flatten.d.ts) and created a tsconfig.json file for you.

Could not parse tsconfig.json. Please make sure it contains syntactically correct JSON.

HI @paulbiba, sorry you've hit this issue.

I think this was resolved with:
#6022

The plan is to release this with v2.1.4. In the mean time, you could try this -

1. Go into your node_modules folder.
2. Go to react-scripts/scripts/utils/verifyTypeScriptSetup.js
3. Copy the changes from here: https://github.com/facebook/create-react-app/blob/fc75002ca3746a61b1e7d28c89ea47bf4245640c/packages/react-scripts/scripts/utils/verifyTypeScriptSetup.js

Then try restarting, and see if that works. If it does or doesn't, please let me know ASAP :)
