 * Hi,
 * I am using w-env to develop a block
   But when I run “wp-env start” and it stops
   with an error:
 * **20 [17/17] RUN composer global require –dev yoast/phpunit-polyfills:”^1.0″**
 * **20 ERROR: process “/bin/sh -c composer global require –dev yoast/phpunit-polyfills:\”
   ^1.0\”” did not complete successfully: unable to find user Mahrokh: no matching
   entries in passwd file**
 * I am using windows 10 and installed Docker Desktop, Git and “npm -g install [@wordpress](https://wordpress.org/support/users/wordpress/)/
   env”
 * “Mahrokh” is the user name of my Windows
 * Thank you for any help

 * Hi [@maahrokh](https://wordpress.org/support/users/maahrokh/)
 * Are you using the WSL2 backend for Docker on Windows? In the [prerequisites](https://developer.wordpress.org/block-editor/reference-guides/packages/packages-env/#prerequisites)
   section of `wp-env`‘s docs it’s said:
 * > There are instructions available for installing Docker on [Windows](https://docs.docker.com/desktop/install/windows-install/)(
   > we recommend the WSL2 backend),
 * If you don’t know what backend you’re using, you could [uninstall](https://docs.docker.com/desktop/uninstall/)
   Docker, and re-install again using the WSL2 backend.

 * Thank you for your support,
 * That was my fault, I should run the `npm -g install @wordpress/env` before the`
   wp-env start`
