是否可以在Mac Os 10.7.5上安装ruby 2.3.4？

Question

I would like to upgrade to Rails 5.1

I am using an old mac computer with OS 10.7.5 and, on my understanding, I can not upgrade the operating system to a newer version. If there is a way, please let me know. I am developing on this computer using Rails 4.2.6. I want to upgrade to Rails 5.1 but, it will need Ruby >= 2.2.2. My ruby 2.1.1 is the better I can get, according to rbenv install --list . I tried reinstalling rbenv and ruby-build and upgrading them but, the rbenv install --list doesn't upgrade to the newest versions of ruby.

To give you heads up, .rbenv/plugins does not exist in my computer.

I read and tried all the suggestions I found on stackoverflow.com and google similar to my case but, none of them worked for me.

Any suggestion will be welcome.

Thanks in advance,

if your mac can use 10.7.5 you can upgrade your mac to version 10.11 (I'm using it so I can answer it) my opinion your for your ruby version is deal with homebrew you can upgrade your homebrew and then from homebrew you upgrade rbenv and so on.

Below is some step by step to install rails with RBENV, probably you can follow along, what command that probably you missed

1. rbenv versions

   • check your rbenv version
   • if you think you need to upgrade you can use command below
   • brew upgrade rbenv ruby-build

2. rbenv install -l

   • check list of ruby that can be installed with rbenv

3. rbenv install 2.3.1

   • this is sample to install ruby version 2.3.1
   • ruby will be copied to /Users/%your_user_name%/.rbenv/versions/2.3.1
   • this is just sample version, use the latest / stable from command number 2

4. rbenv global 2.3.1

   • set global ruby to version 2.3.1

5. rbenv local 2.1.1

   • after you set global (with version 2.3.1) in case you want specific folder with version 2.1.1 you can set local folder with this command, so the new ruby Don't messed up your old project

6. rbenv rehash

   • this command will apply new ruby version that you just install
