貌似只有几个 bugfix 果断rvm install ruby-1.9.3-p125

rvm reinstall 1.9.3-head

将 rvm 更新了一下，list known 还是没找到这个版本。 rvm upgrade 1.9.3-p0 1.9.3-p125 不成功。

ruby -v ruby 1.9.3p129 (2012-02-17 revision 34654) [i686-linux]

#3 楼 @hhuai

rvm get stable
rvm install 1.9.3

#5 楼 @zhangyuan 我想直接 p0 升级到 p125，不想又多装一个，再迁移 gemset 之类。

这个版本有没有加那个 falcon 的 patch？加速的那个

看 change log 加了 llvm 的 support 是不是在 lion 下安装的时候会方便些

#6 楼 @hhuai 哈哈，我以前都是重新创建 gemset 再安装 gems。刚才看了一下，还有 rvm gemset copy ruby-1.9.3-p0@rails3 1.9.3-p125@rails3 这个命令。

唉。。。。。以后研究 ruby 代码还要 tm 学日语。。。唉

#10 楼 @jinleileiking 你真能扯淡

#11 楼 @hooopo 不是扯淡，我看完 lua 代码，下一步就打算研究 ruby 源代码了。。。

鸡血补丁什么时候被 merge 啊

#4 楼 @hooopo 用你的方法，发现又到 133 了。。。

ruby -v
ruby 1.9.3p133 (2012-02-17 revision 34660) [i686-linux]

#14 楼 @bindiry 是哇 还是我的方法好:-) 这东西是从 master 分支 check 出来的 修复一个 bug 就会 +1

#3 楼 @hhuai

#15 楼 @hooopo

#14 楼 @bindiry

正解： rvm get latest # rvm 更新至最新版本，才能看见 1.9.3 的树 rvm list known 才有 1.9.3 .... rvm install 1.9.3

另外发现了加入 md 的 bug。。。。

#4 楼 @hooopo 你这个到不 stable 的版本，万一有 bug，不傻了，还是别 head 了。。

rvm get head
rvm install 1.9.3-falcon

#18 楼 @jinleileiking 开发环境你怕什么
