[Catalyst-dev] Linux::Inotify2 causing dev server with auto restart to fail

[Mauritz Hansen]

Hi folks,

I am busy developing an application with Catalyst. Everything has been
working fine until this morning. Suddenly I got the following error when
starting the development server:

Attribute (_inotify) does not pass the type constraint because:
Validation failed for 'Linux::Inotify2' with value undef at constructor

at /usr/share/perl5/File/ChangeNotify/Watcher/Inotify.pm line 198) line

After a bit of experimenting I found that I could start the server by
leaving off the '-r' flag. I 'fixed' this problem by removing the
Linux::Inotify2 module - it was probably installed as an optional (I
hope) dependency of another module. Anyway, with the presence of this
module the '-r' flag does not seem to work.

I am using the following software:
Linux::Inotify2 version 1.2 (which I have now removed)
Perl 5.12.4
Catalyst 5.90010
