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® Core™ 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 facebook/jest@800f2f803d01c8ae194d71b251e4965dd70e5bf2 (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>'

The same is true without “CI=true”.

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?
