ruby-on-rails - ruby 2.1 rails 4 和 ZenTest 4.9.5 - multigem 错误

Question

我正在设置一台新计算机并尝试捆绑安装一个项目——我得到：

ZenTest's executable "multigem" conflicts with /Users/grimm/.rvm/rubies/ruby-2.1.0/bin/multigem
Overwrite the executable? [yN]  n
ERROR:  Error installing ZenTest:
"multigem" from ZenTest conflicts with /Users/grimm/.rvm/rubies/ruby-2.1.0/bin/multigem

我可能会为此转向 Ruby2.0，但很好奇为什么没有其他人收到此错误？
