Question

更新：当我使用sudo（例如sudo rbenv install jruby-9.1.2.0）时，一切正常。但我不希望这样:)。

$ ruby -v
NameError: undefined local variable or method `v' for main:Object
<top> at -v:1

$ sudo ruby -v
jruby 9.1.2.0 (2.3.0) 2016-05-26 7357c8f Java HotSpot(TM) 64-Bit Server VM 25.51-b03 on 1.8.0_51-b16 +jit [darwin-x86_64]

在安装过程中寻找有关在哪里查找需要sudo的内容的提示。 C Ruby安装/运行没有sudo。

尝试安装JRuby但遇到问题-r标志被解释为变量。使用rvm和JRuby 1.7.x版本时的类似问题。同事没有任何相同的问题。之前能够使用rvm和rbenv安装JRuby 1.7，并且从那时起我就不知道系统上发生了什么变化。尝试JAVA_HOME设置为1.7和1.8版本具有相同的结果。

我无法弄清楚我的系统上是什么造成了这个问题 - 在重新成像之前寻找有关故障排除的想法：）。

这是我的操作系统信息

$ uname -a

还有jruby-launcher的问题，但不确定这只是一个症状：

$ gem install jruby-launcher
ERROR:  Could not find a valid gem 'jruby-launcher' (>= 0) in any repository
ERROR:  Possible alternatives: tmux_launcher, RubyRun_CE, ass_launcher, ec2launcher, jruby-ehcache

Answer 1

更新：使用-S中的JRUBY_OPTS选项显示是罪魁祸首。

我在用户会话中取消设置所有环境变量，并确保env完全匹配sudo env，但以下情况除外：

MAIL
LOGNAME
USER
USERNAME
SUDO_COMMAND
SUDO_USER
SUDO_UID
SUDO_GID

然后使用没有sudo的用户，我可以毫无问题地安装JRuby。

现在，即使有与我遇到问题时完全相同的环境变量，我现在可以在闲暇时安装/执行JRuby。仍然不知道为什么会这样，或者哪个环境变量有问题。

JRuby安装失败，除非sudo带有“未定义的局部变量或方法`r'for main：Object”
