composer make-pot fails on mac when site path contains a space

[mrlowe]

Eg if you're using Local by Flywheel with the default Local Sites directory:

$ composer make-pot
> wp i18n make-pot . languages/_s.pot
/Users/nobody/Local Sites/edgio/app/public/wp-content/themes/edgio-theme/vendor/bin/wp: line 17: cd: ../wp-cli/wp-cli/bin: No such file or directory
/Users/nobody/Local Sites/edgio/app/public/wp-content/themes/edgio-theme/vendor/bin/wp: line 39: /wp: No such file or directory
Script wp i18n make-pot . languages/_s.pot handling the make-pot event returned with error code 127

Maybe an issue with the value returned by realpath?
