RVM:在系统范围的安装中从.rvmrc文件加载gemset时权限被拒绝

Question

我创建了一个.rvmrc包含自定义gemset 的项目特定文件(使用该命令rvm --rvmrc --create 1.9.2@registration):

# excerpt of .rvmrc...

environment_id="ruby-1.9.2@registration"

if [[ -d "${rvm_path:-$HOME/.rvm}/environments" \
  && -s "${rvm_path:-$HOME/.rvm}/environments/$environment_id" ]]
then
  \. "${rvm_path:-$HOME/.rvm}/environments/$environment_id"

  if [[ -s "${rvm_path:-$HOME/.rvm}/hooks/after_use" ]]
  then
    . "${rvm_path:-$HOME/.rvm}/hooks/after_use"
  fi
else
  # If the environment file has not yet been created, use the RVM CLI to select.
  if ! rvm --create  "$environment_id"
  then
    echo "Failed to create RVM environment '${environment_id}'."
    return 1
  fi
fi

这可以在我的Mac上本地使用单用户RVM.我们还使用Vagrant在我们的Vagrant盒子上安装了系统范围的RVM.但是,当我们cd进入项目目录并接受该.rvmrc文件时,会产生以下消息(是的,有很多重复的错误消息):

mkdir: cannot create directory `/usr/local/rvm/gems/ruby-1.9.2-p318@registration': Permission denied
-bash: /usr/local/rvm/environments/ruby-1.9.2-p318@registration: Permission denied

mkdir: cannot create directory `/usr/local/rvm/wrappers/ruby-1.9.2-p318@registration': Permission denied

尝试手动创建gemset会提到相同的错误,但也提到它是成功的:

$ rvm use 1.9.2
Using /usr/local/rvm/gems/ruby-1.9.2-p318
$ rvm gemset create registration
mkdir: cannot create directory `/usr/local/rvm/gems/ruby-1.9.2-p318@registration': Permission denied
'registration' gemset created (/usr/local/rvm/gems/ruby-1.9.2-p318@registration).

我有错误的配置吗？如何解决此问题,以便我可以使用.rvmrc文件中的自定义gemset ？

问题是我使用的简单Chef配方没有将vagrant用户添加到rvm组中.这可以通过这样做来实现:

sudo usermod -a -G rvm vagrant

但我决定转而使用更健壮的RVM Chef食谱,这些食谱完美地运用了这些食谱:

include_recipe "rvm::system"
include_recipe "rvm::vagrant"
