# Post installation test

Had to install a specific version of FPM to get it to work:

gem1.8 install fpm --no-ri --no-rdoc -v 1.2.0

Thanks @futuremill for sharing, you saved my day!
And thanks to you @thejandroman for your tip regarding the version of FPM to install.

@andrejko You're right, an it might also be dpkg -i ruby193-1.9.3-p125_amd64.deb if you're on a x64 arch (that said, simply look at the generated package).

Edit: you might also want to force installing FFI ~ 1.9.10 as installing FPM may complain about FFI not being compatible with Ruby < 1.9.
The first lines should then be:

apt-get install ruby rubygems # Need ruby to use fpm
gem1.8 install ffi --no-ri --no-rdoc -v 1.9.10
gem1.8 install fpm --no-ri --no-rdoc -v 1.2.0
