RainLab.Debugbar : Plugin has been removed from the file system

[iscisse]

Hello.
I am using winter 1.2.6.
I try to install the debug bar with composer require --dev winter/wn-debugbar-plugin and php artisan migrate.
Now i have 2 issues:

1. I get the message:
   Some issues have been detected and require attention:
   The NapAgency.DebugPLus plugin requires Bedard.Debugbar to be installed before it will work
2. in the list of plugins it says:
   RainLab.Debugbar : Plugin has been removed from the file system

when i run php artisan:list I get
+----------------------+---------+-----------------+----------------+
| Plugin name | Version | Updates enabled | Plugin enabled |

| Winter.Demo | 1.0.1 | Yes | Yes |
| Winter.Blog | 2.0.0 | Yes | Yes |
| Winter.Builder | 2.0.0 | Yes | Yes |
| RainLab.Debugbar | 3.3.7 | Yes | Yes |
| Skripteria.Snowflake | 1.0.4 | Yes | Yes |
+----------------------+---------+-----------------+----------------+

What am I doing wrong ?

@iscisse Why are you trying to install NapAgency.DebugPLus? I'm pretty sure it doesn't work and the functionality it provides is already available in Winter.DebugBar.

Also try switching to the develop branch, there's been a lot of bug fixes since our last release.
