如何使用Rails & Heroku在RVM中设置默认的gemset

I need to specify a ruby version in my Gemfile for Heroku:

我需要在我的Gemfile中为Heroku指定一个ruby版本:

ruby '2.1.1'

That works as expected. However, it messes with my local terminal as well. I try to set the default ruby version and gemset in RVM with:

像预期的那样工作。但是，它也会影响到我的本地终端。我尝试将RVM中的默认ruby版本和gemset设置为:

$ rvm --default use ruby-2.1.1@rails4
Using /Users/scott/.rvm/gems/ruby-2.1.1 with gemset rails4
$ rvm gemset list

gemsets for ruby-2.1.1 (found in /Users/scott/.rvm/gems/ruby-2.1.1)
   (default)
   global
=> rails4

Seems fine and it works as expected. However, if I open up another terminal shell I get this:

看起来很好，而且运行正常。但是，如果我打开另一个终端外壳，我会得到:

RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /Users/scott/code/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

$ rvm gemset list

gemsets for ruby-2.1.1 (found in /Users/scott/.rvm/gems/ruby-2.1.1)
=> (default)
   global
   rails4

I want it to use the rails4 gemset always! How can I do this?

我想让它永远使用rails4 gemset !我该怎么做呢?

Only way you could do it is to add two files to your application: .ruby-version and .ruby-gemset and add 2.1.1 in the .ruby-version file and rails4 in the .ruby-gemset file.

惟一的方法是向应用程序添加两个文件:.ruby版本和.ruby-gemset，并在.ruby版本文件中添加2.1.1，在.ruby-gemset文件中添加rails4。

You can also do this on your command line with:

您也可以在命令行中这样做:

echo 2.1.1 > .ruby-version

and

和

echo rails4 > .ruby-gemset

And that will create the files for you with the version 2.1.1 and the gemset rails4

这将为您创建版本2.1.1和gemset rails4的文件。

So whenever you open a new terminal, rvm will use ruby 2.1.1 and gemset rails 4

因此，每当您打开一个新的终端时，rvm都会使用ruby 2.1.1和gemset rails 4
