我无法fakes3在El Capitan Beta 5上安装和运行gem.

我试过了:

sudo gem install fakes3
ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted - /usr/bin/fakes3

然后我尝试用cocoapods方式做.它适用于cocoapods,但不适用于fakes3.

mkdir -p $HOME/Software/ruby
export GEM_HOME=$HOME/Software/ruby
gem install cocoapods
[...]
1 gem installed
gem install fakes3
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

我成功安装了Sass,但是我无法导入Compass.

以下是错误详细信息:

*Syntax error: File to import not found or unreadable: compass.
              Load path: H:/HTML/___keoFull/sass

我试图让自己在Mac上学习Ruby on Rails,但是我似乎遇到了一些问题.如果我尝试运行./script/server等命令,我会得到:

Rails需要RubyGems> = 0.9.4(你有0.9.2).请gem update --system再试一次.

当我运行"gem update .."时,我得到了这个:

更新RubyGems ...尝试远程更新rubygems-update错误:执行gem时...(Errno :: EACCES)权限被拒绝 - /opt/local/lib/ruby/gems/1.8/cache/rubygems-update-1.3. 0.gem
