Question

1. 乾淨的山獅安裝
2. 從App Store
3. 安裝的XCode 4.5安裝命令行工具
4. 安裝家釀
5. 釀造醫生也很高興
6. 安裝RVM
7. RVM安裝1.9.3
   • 安裝程序要求更多的啤酒，安裝以下軟件：
     1. 蘋果gcc42
     2. autoconf的
     3. automake的
     4. libksba

安裝完成後，一切看起來都不錯.. 。

Answer 1

它看起來像你的PATH中有/Users/mmoser/.rvm/scripts/，這不會偶然發生 - 你必須手動添加它，請刪除它，並再次安裝寶石。

它也需要重新安裝紅寶石，因爲INSTALL錄得紅寶石：

$ rvm config-get INSTALL 
/usr/bin/install -c 

這樣跑：

rvm reinstall all
