與鐵軌和寶石安裝多個錯誤

Question

安裝OSX 10.8.5後，我開始有一些錯誤，並仔細閱讀stackoverflow後帖子我沒有找到正確的答案。我會很感激你的幫助

當我嘗試安裝libyaml我有一些警告

$ sudo rvm pkg install libyaml 

Beware, 'rvm pkg ...' is deprecated, read about the new autolibs feature: 'rvm help autolibs'.

Please note that it's required to reinstall all rubies: 

    rvm reinstall all --force 

。

$ sudo rvm reinstall all --force

非常感謝您的幫助

Answer 1

首先，使用sudo與RVM導致要避免各種文件的權限問題，從不使用sudo rvm。

這裏更多的信息：通過運行

sudo chown -R $USER: ~/.rvm

不管怎麼說，安裝libyaml你應該使用自制http://rvm.io/rubies/rubygems

如果您已經使用sudo gem install ..就可以解決您的RVM權限。看起來你需要安裝libyaml然後重新安裝你的Ruby。嘗試：

$ brew install libyaml 
$ rvm reinstall 2.0.0 

編輯：基於上面的代碼

，看起來你有自制的一些問題。嘗試運行

$ brew doctor 
$ rvm install ruby-2.0.0-p247 

如果這些運行完成，那麼您可以再次嘗試libyaml。

$ brew install libyaml 

如果這些仍然返回該bad interpreter: no such file or directory錯誤，那麼試試這個修復它。

Answer 2

/usr/local/lib/ruby/2.0.0/不RVM紅寶石 - 你需要說rvm使用已安裝的紅寶石：

rvm list 

它會顯示類似：

ruby-1.9.3-p448 [ x86_64 ] 
    ruby-2.0.0-p247 [ x86_64 ] 

你可以說RVM使用2.0.0紅寶石：

rvm use 2.0.0-p247 

另外答案也是如此 - 永不使用sudo
