[rt-users] upgrade-assets error

[support at pureview.com]

Hello everyone,

After I upgrade my RT to 4.4.1 on centos 6. I'm trying to run the
assets-upgrade and I'm getting the error below.

How do I solve this issue. I remove the plugin from the configuration
already.

## ERROR
/upgrade-assets
Can't locate RT/Interface/CLI.pm in @INC (@INC contains: lib local/lib
/usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at
./upgrade-assets line 56.
BEGIN failed--compilation aborted at ./upgrade-assets line 56.

Thank you.
David
