[micalgenus]

PS. I do not speak English well. Please understand.

Is this a bug report?

Yes

Did you try recovering your dependencies?

yes / Initialized project with npx create-react-app my-project

Which terms did you search for in User Guide?

jest, jest version

Environment

$ npx create-react-app --info
npx: installed 63 in 8.392s

Environment Info:

System:
OS: Linux 4.4 Ubuntu 18.04.2 LTS (Bionic Beaver)
CPU: x64 Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz
Binaries:
Node: 11.11.0 - ~/.nvm/versions/node/v11.11.0/bin/node
Yarn: 1.13.0 - /usr/bin/yarn
npm: 6.7.0 - ~/.nvm/versions/node/v11.11.0/bin/npm
npmPackages:
react: ^16.8.4 => 16.8.4
react-dom: ^16.8.4 => 16.8.4
react-scripts: 2.1.8 => 2.1.8
npmGlobalPackages:
create-react-app: Not Found

Steps to Reproduce

1. install node version 11.11. (only over 11.11. There is no problem with other versions.)
2. npx create-react-app myproject && cd myproject
3. yarn test # this step error

Expected Behavior

Currently, the LTS version of node.js is 10, but will change from 2019-04-01 to version 11. That's why I think we need to fix the problem.

This problem has been fixed as follows after jestjs/jest@800f2f8 (v24.2.0-alpha.0).

newProcess[Symbol.toStringTag] = 'process';

modify to

 try {
    // This fails on Node 12, but it's already set to 'process'
    newProcess[Symbol.toStringTag] = 'process';
  } catch (e) {
    // Make sure it's actually set instead of potentially ignoring errors
    if (newProcess[Symbol.toStringTag] !== 'process') {
      e.message =
        'Unable to set toStringTag on process. Please open up an issue at https://github.com/facebook/jest\n\n' +
        e.message;

      throw e;
    }
  }

I used the 10.15.3 node and tried the 24.3.0 Jest. As a result, it worked fine. But I have not tested it for other versions of the node.

Actual Behavior

$ CI=true yarn test
yarn run v1.13.0
$ react-scripts test
FAIL src/App.test.js
  ● Test suite failed to run

    TypeError: Cannot assign to read only property 'Symbol(Symbol.toStringTag)' of object '#<process>'

[jmarlow4]

I'm getting the same error

[viktorlarsson]

Experiencing the same on node@latest, downgrading to node 10.6.0 makes everything fine and dandy.

[huxaiphaer]

Me too the same error. Hey @viktorlarsson what if reactjs ?

[soer7022]

Got the same error on the latest node image

There is no error with node v11.10.1, but it is with v11.11.0
Example v11.10.1:

npx create-react-app my-app
cd my-app
docker run -it --rm -v $(PWD):$(PWD) -w $(PWD) node:11.10.1-alpine yarn test

 PASS  src/App.test.js (13.661s)
  ✓ renders without crashing (48ms)

Example v11.11.0:

npx create-react-app my-app
cd my-app
docker run -it --rm -v $(PWD):$(PWD) -w $(PWD) node:11.11.0-alpine yarn test

Please fix this :(

If you need to get this to work with node 11.11 and you cannot downgrade...

It is already fixed with newer jest version.
You can upgrade your own jest version besides create-react-app by installing jest-util@^23.4.0
Also you have to create a .env-File and to bypass the Preflight-Check.
echo "SKIP_PREFLIGHT_CHECK=true" >> .env

The complete cmd that solves the issue for myself is:
echo "SKIP_PREFLIGHT_CHECK=true" >> .env && npm i jest-util@^23.4.0 --save-dev

Until create-react-app has updated to newer jest-version, we can remove jest from our package.json and also reactivate this skipped preflight-check.

[soer7022]

if you use gitlab CI you can change image: node:latest into image: node:10.6.0

[Marjona6]

What worked for me was changing the version of Jest to 24.3.0. I also had to remove the lockfiles and reinstall before tests passed again on Travis. Hope this helps.

[FezVrasta]

node@11.10.0 works fine, you don't need to downgrade to 10.6. The one with problems is node@11.11.0

As @Marjona6 stated it's fixed since version 24.3.0 so this issue should be closed.

[goldo]

its not fixed in create-react-app since it doesn't bring jest 24 with it. It should be "awaiting" for this PR to be merged: #6278

[jonraem]

OK, my problem was that my bitbucket-pipelines.yml was using an unspecified version of alpine, which selects the latest one by default. It was a simple fix at the end and a silly overlooked mistake on my part. In other words I changed images with node:alpine to node:10.15-alpine.

Hey guys, lot of people are subscribed to this issue to be warned when a fix gets released. Please may you refrain from posting all your very own personal solutions that explain how did you downgrade your Docker images to use node <11.11 please?

[ldco2016]

None of the solutions in this thread have helped me, so yes, please refrain from posting what personally worked for you until a solution exists that works for everybody, this is frustrating.

How are you supposed to know if it works for everyone or not?

[ianschmitz]

We've released an alpha of create-react-app 3.0. Head on over to #6475 for instructions to install the latest alpha build which includes Jest 24. Let us know if it solves this issue!

[yurtaev]

@ianschmitz Yes, it solved the problem 👍

[yurtaev]

node 11.12 fixed it

[nartoland]

Ok

[ianschmitz]

Closing as it sounds like this is resolved in Node 11.12
