I'm trying to learn Ruby. I want to use more versions than what's on my system. I have 10.6.8 and kinda like it so don't want to upgrade, and others say I don't have to upgrade. How can I run more than Ruby 1.8? The Ruby page says rbenv or RVM can do this, but are they safe? I don't want to break my compuetr.
Perhaps you can download the source code for Ruby and install it in your /usr/local directory. Make sure you read a few tutorials on how to set it up beforehand.
Once it's compiled with the typical
$./configure
$ make
$ make install
You can then try using. It should probably be installed in /usr/local/bin
If you can't find it, try this
$find /|grep ruby
Good luck!

Mac OS controls versions of things and that makes it stable.
RVM site says it is good at not breaking the OS. Is your idea of compiling my own program safer than the tools?
I'm not sure, since I haven't tried RVM yet. Looks interesting though. I've dabbled with it, but not in depth.
Safety all depends on what you know about Linux, and I'm sure you know quite a bit, since you are programming Ruby.
I just tuned up a few things on my system lately and realize that out of the box OSes and Apps, and the internet in general, is not secure. The enduser has to figure that out for him/herself
(ex: suid, sgid like rlogin rsh are set with the following permissions and the Disk Utility's "Repair Permissions" suggestions are generally quite good. Not so good on the rlogin, rsh ... programs though.
I guess you could say the same applies to your compiling your own program (ruby src). If you understand how ruby works, you can set it up, choose the options that you need and have a "safe" ruby.
I do however like how port sets things up. It's generally quite clean since it finds and knows what which dependencies to install.
I'm sure you understand this.
"Safe" was more about putting self-compiled programs into the Apple-controlled program space. Remote access is the unsafest thing and that is why I only allow things I really understand as "outside access".
Is adding different versions of something already in the computer asking for trouble?
Hi folks I have a laguage-type question
