ruby - 使用 rvm install ruby​​ 2.0.0 时权限被拒绝的问题

Question

我找了很多内容，还是没找到是什么原因，我确定rvm文件夹权限应该是对的。

$ rvm get stable

A RVM version 1.20.13 (master) is installed yet 1.20.13 () is loaded.
Please do one of the following:
  * 'rvm reload'
  * open a new shell
  * 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg.
  * 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.

并检查 rvm 版本:

$ rvm --version

rvm 1.20.13 (master) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

然后安装ruby 2.0.0:

$ rvm install 2.0.0

mkdir: /Users/xudannie/.rvm/log/ruby-2.0.0-p195: Permission denied
mkdir: /Users/xudannie/.rvm/log/ruby-2.0.0-p195: Permission denied

Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.7/x86_64/ruby-2.0.0-p195.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.

刚开始学习ROR，需要面对的问题太多了。

希望得到您的帮助!

尝试运行 sudo rvm install 2.0.0 如果这不起作用就运行 sudo chmod a+rw -R ~/.rvm 然后 rvm install 2.0.0 再一次。
