我见过一对夫妇类似的问题，但该决议似乎总是那个目标目录不存在或所有者是root。 我检查了，我的目录存在，是由我所拥有并有权755。
更新
我尝试了很多东西，所以我不是100％肯定这是相关的，但我更新RVM，然后我就能够运行refinercyms goodwatching从原来的/ goodwatching目录内。 但现在，当我运行它，我得到这个多次：
NoMethodError: private method `open' called for Gem::Package:Class
An error occured while installing rake (10.0.4), and Bundler cannot continue.
Make sure that `gem install rake -v '10.0.4'` succeeds before bundling.
当我运行gem install rake -v '10.0.4'确实succede，但后来我后立即再次得到了同样的错误。
