问题 I'm trying to install ruby 2.2.4 or 2.3.0 on my Synology DS215j which has an ARMv7 processor. I used optware-ng to install gcc, make, openssl, openssl-dev and zlib. I installed rbenv (version 1.0.0-19-g29b4da7) and the ruby-build plugin according to the instructions in the README. These are the package and their versions installed with optware-ng binutils - 2.25.1-1 gcc - 5.3.0-6 gconv-modules - 2.21-3 glibc-opt - 2.21-4 libc-dev - 2.21-1 libgmp - 6.0.0a-1 libmpc - 1.0.2-1 libmpfr - 3.1.3-1

问题 I'm trying to run a ruby script using rbenv with cron. I know that I need to load rbenv in order to have the right ruby version loaded.

How do you use multiple rails versions with rbenv?

阅读更多关于 How do you use multiple rails versions with rbenv?

问题 Is it possible to use multiple versions of rails using rbenv (e.g. 2.3 and 3.1)? This was easy with gemsets in rvm, but I'm wondering what the best way is to do it now that I've switched to rbenv (also, I'm looking for a way to do it without rbenv-gemset). 回答1: not sure if you got an answer to this, but I thought I'd offer what I did and it seemed to work. So once you get rbenv installed, and you use it to install a specific ruby version, you can install multiple versions of rails to for that
