Termux-packages: create-react-app error: cb() never called!

[tchoutri]

Problem description
Using create-react-app after having installed with npm i -g create-react-app results in a fatal error.
I saw several people on the Internet recommending to erase the cache, but this workaround did not work.

Steps to reproduce

1. pkg i nodejs
2. npm i -g create-react-app
3. create-react-app app

Expected behavior
I would have expected a bootstrapped React app

Attempted to reproduce, didn't get any errors from npm. Only got an error from create-react-app due to it attepting to hardlink.

To create an app without the linkSync error, create the app directory with a gitignore before running create-react-app.

$ mkdir app
$ touch app/.gitignore
$ create-react-app app

Success! Created app at /data/data/com.termux/files/home/app
Inside that directory, you can run several commands:

  yarn start
    Starts the development server.

  yarn build
    Bundles the app into static files for production.

  yarn test
    Starts the test runner.

  yarn eject
    Removes this tool and copies build dependencies, configuration files
    and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

  cd app
  yarn start

Happy hacking!
