我使用Debian Linux在Raspberry Pi上安装了rvm和Ruby 1.9.3p194。当我使用gem install pry
安装pry时,一切都安装完美,但是在终端中键入pry无法正常工作:
pi@raspberrypi ~ $ pry
bash: pry: command not found
~/.rvm/gems/ruby-1.9.3-p194/bin
中有一个 pry 文件。我必须在同一目录中用ruby_noexec_wrapper调用它:pi@raspberrypi ~ $ .rvm/gems/ruby-1.9.3-p194/bin/pry
/usr/bin/env: ruby_noexec_wrapper: No such file or directory
pi@raspberrypi ~ $ cd .rvm/gems/ruby-1.9.3-p194/bin
pi@raspberrypi ~/.rvm/gems/ruby-1.9.3-p194/bin $ ./ruby_noexec_wrapper pry
[1] pry(main)>
在此Linux中运行 pry 动的正确方法是什么?在Windows和Mac OS X上,我可以在任何命令提示符或终端上简单地键入pry。
更新:这是我的

最佳答案
首先确保rvm已正确加载:
type rvm | head -n 1 # should be: rvm is a function
type gem | head -n 1 # should be: gem is a function
如果它们不是函数,这意味着RVM没有正确加载,这可能是您的Shell中的错误(例如受限的bash),您可以尝试使用以下方法修复它:
rvm get head --auto
在运行此命令后,可能需要重新登录以运行所有 shell 程序配置文件。
接下来,请确保您使用rvm:
rvm use 1.9.3
echo $PATH
echo $GEM_PATH # those two need match those from `rvm info`
rvm info
您还可以将一个 ruby 设置为默认值:
rvm use 1.9.3 --default
刷新PATH-输入终端
hash -r # OR:
PATH="$PATH"
甚至重新登录都应该对此有所帮助。
