如何用 rvm 或 rbenv 來 wide install ruby? about ama

[zackexplosion]

之前有想過這問題，不過這東西基本上就是利用 User 把環境隔開，如果特別把他裝 Global 似乎就失去原本故意隔開的意義了。

這裡有一篇文章，你可以參考看看，主要就是把 RBENV_ROOT 給換掉的樣子

用 root 裝 ruby...
root 裝的 ruby 每個 user 都可以用..
(記的是這樣..path 設好就好了..)..

好像都是不錯的方法，不過我現在在想..
我會有這個問題是，我在架設新的環境時，執行sudo gem install .........
會有sudo: gem: command not found的錯誤
遇到這種情形一般會怎麼解決?

如果是 RVM 的話：

Multi-User installations - For server administrators - For an installation usable by all users on the system - Please note that Single-User supersedes Multi-User. This also used to be called the System-Wide Install. Using this type of installation without knowledge how umask works is a big security risk.

For a Multi-User install you would execute the following:

\curl -sSL https://get.rvm.io | sudo bash -s stable

sudo: gem: command not found 問題解法：

rvmsudo
