create-react-app: React-scripts test command not working
Describe the bug
react-scripts test
command stopped working after update to ^4.0.3 from ^3.0.0.
It shows this error on terminal:
● Validation Error:
Watch plugin jest-watch-typeahead/filename cannot be found. Make sure the watchPlugins configuration option points to an existing node module.
Configuration Documentation:
https://jestjs.io/docs/configuration.html
error Command failed with exit code 1.
Nothing has changed on the code. Only react-scripts package. Tests were working fine before the update. The project is not ejected and it is not intended to be.
Did you try recovering your dependencies?
Yes, I tried. yarn version: 1.22.10
Which terms did you search for in User Guide?
I’ve search for ‘react-scripts test’ and ‘watchPlugins’ and all I found is that I need to eject the project. I don’t understand why. It was never like that. So I think that is not the solution to the problem.
Steps to reproduce
- Open a terminal on the CRA project root
- Run
yarn
- Run
yarn test
Expected behavior
I expect tests run fine. Like before updating to ^4.0.3.
Actual behavior
react-scripts test
command stops working after update react-scripts library to ^4.0.3 from ^3.0.0.
It shows this error on terminal:
● Validation Error:
Watch plugin jest-watch-typeahead/filename cannot be found. Make sure the watchPlugins configuration option points to an existing node module.

Thank you 😄

I have had the same issue and one important thing to notice is that the newest released version of
jest-watch-typeahead
is now written in native ESM and will break with the following error:Error [ERR_REQUIRE_ESM]: Must use import to load ES Module
Make sure to install the version compatible with Jest 26 e non native ESM modules.
I’ve fixed it by installing the plugin jest-watch-typeahead

Had the same issue after updating
react-scripts
4.0.3
→5.0.1
.It’s not necessary to add
jest-watch-typeahead
as a dependency to thepackage.json
, no-save install was enough in my case:npm install --no-save jest-watch-typeahead@1.1.0
Running
npm ci
might be more robust solution, though.I noticed that I didn’t have
jest-watch-typeahead
in mynode_modules
. Installing it solved the problem:npm install --save-dev jest-watch-typeahead
That’s a workaround of course rather than solving the problem.
