I’m trying to install mental (that works fine) but want to use the part\_assets extensions. I’ve already found that act\_as\_attachements wants RMagick to run but apparently it needs more ☹ Complete traceback to follow.

Your problem is that you’ve downloaded acts\_as\_attachment as an extension - it’s not an extension, it’s a plugin (should be under vendor/plugins, not vendor/extensions). Also, have you install part\_assets (from [soxbox.no-ip.org](http://soxbox.no-ip.org)) or page\_attachments (from [seancribbs.com](http://seancribbs.com))? If it’s part\_assets, it doesn’t have any dependency on acts\_as\_attachment. The big gotcha at the moment is that I renamed it to part\_attachments but haven’t rejigged my repository to reflect that, so you’ll have to rename the directory manually. It wants fleximage and rmagick installed, but should be able to work without them (though it will fall over if you install fleximage without rmagick). In fact, I’ll just fix my repository now - I’ll make another blog post with installation instructions and get back to you. Dan. ---
