在Shell脚本中切换红宝石 [英] Switching rubies in shell script

问题描述

执行bash shell脚本时，我使用的是ruby 1.9.3.然后，在脚本中，我想切换到JRub(我正在使用rvm).我尝试通过在脚本中执行rvm use jruby切换到JRuby，但这没有用，它说:

When executing a bash shell script I am using ruby 1.9.3. Then, within the script, I want to switch to JRub (I'm using rvm). I tried switching to JRuby by doing rvm use jruby within the script, but this didn't work, it said:

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

./run.sh: line 10: jruby: command not found

在命令提示符下执行type rvm | head -n1时，得到:rvm is a function.所以我不确定这个问题.我认为这可能是因为我使用sudo(sudo rvm install jruby)安装了JRuby.因此，我再次使用sudo运行了shell脚本.我再次收到错误消息.

When I do type rvm | head -n1 at the command prompt, I get: rvm is a function. So I'm not sure of the problem. I thought it might be because I installed JRuby using sudo (sudo rvm install jruby). So I ran the shell script again using sudo. Again I received the error.

如何使用rvm从bash shell脚本中切换红宝石?

How can I switch rubies from within a bash shell script with rvm?

谢谢

推荐答案

我最终将其添加到以下行:

I ended up adding this to the line before:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

如该线程中所述(很抱歉-虽然我之前知道此线程，但我不太了解它):

as explained in this thread (sorry - though I was aware of this thread before, I didn't quite grasp it):

RVM不会切换红宝石
