问题
I have a very old rails app (rails 2.3.10 and ruby 1.8.7) and we want to move it on another server. I can reinstall all gems with same version except for paperclip 2.7. when i tried to install it i receive an error on activesupport, that it seems it require ruby 1.9.3. According with paperclip doc this shouldn't happens, some one of you can help me? i tried with all gems except paperclip, with no gems, and installing an old version of activesupport. Below you can find my tests.
app@new-server:/home/app/current# sudo gem list
*** LOCAL GEMS ***
app@new-server:/home/app/current# sudo gem install paperclip -v=2.7.0

"activesupport requires Ruby version >= 1.9.3."

You will have to build the gem manually and use the file from the pull request here: https://github.com/thoughtbot/paperclip/pull/1270. - Ralph
