Symfony2 Jobeet tutorial day 3 error invalid mappi

问题:

When I generate bundle entities with code

php app/console doctrine:generate:entities EnsJobeetBundle

I'm getting this error

[Doctrine\Common\Persistence\Mapping\MappingException] Invalid mapping file 'Ens.JobeetBundle.Entity.Affiliate.orm.yml' for class 'Ens\JobeetBundle\Entity\Affiliate'.

This is Affiliate.orm.yml file:

 Ens\JobeetBundle\Entity\Affiliate:

回答1:

Try opening the file in a text editor, and replacing " " with " " globally.

My colleague was having the exact same issue on the same file, and it turns out the problem was that the file was using something other than spaces as spaces. file(1) showed that the file was a UTF-8 Unicode text rather than plain ASCII.

I believe this may be caused by the source of the copy + paste using different space characters.

This yaml .yml configuration files cannot contain TABs. Only spaces as intendation. That is the problem.
