In Heroku, I have been added as a collaborator of a project. I need to get that project in my local. And for that I need to know which Ruby version project has. Rails version of project is 3.1
I knew this via the Gemfile
file.
Please suggest what should I do for that?
对于任何寻找此信息的人来说,获取信息都很简单
heroku run ruby -v
You can know it by the stack use on this project.
heroku stack
If it's not Cedar stack you can have information about ruby version is used on heroku
Exemple of output
$ heroku stack
aspen-mri-1.8.6
* bamboo-mri-1.9.2
bamboo-ree-1.8.7
cedar (beta)
The * represent the stack use on this project and the version is define.
aspen-mri-1.8.6 => MRI 1.8.6
bamboo-mri-1.9.2 => MRI 1.9.2
bamboo-ree-1.8.7 => REE 1.8.7
In case of the stack is cedar. By default the ruby version is 1.9.2 MRI. If it's change by ruby 1.9.3, It's a trick define by config. You can have information by
heroku config
You can have RUBY_VERSION => ruby-1.9.3-p0
define if the ruby 1.9.3-p0 is used.
