Cannot enable relation, always error

Hi there,

Relation was a good module and I want to add this on my site (Drupal 8.2.2), I use drush to install relation module (8.x-1.x-dev) and it goes well.

Then I tried to enable relation module but it make some error:

I@here:/var/www/dev.test$ sudo drush en relation
The following extensions will be enabled: relation
Do you really want to continue? (y/n): y

After that my site just show a message:
The website encountered an unexpected error. Please try again later.

If I just uninstall relation module, the site works again.
Please help.

Thanks
