ruby - 尽管 RVM 插件 Jenkins 使用了错误的 ruby​​ 版本

Question

Jenkins 在 ubuntu 机器上运行。它有一个特殊的用户 jenkins 用于执行作业。
RVM 已安装并在服务器上的 ssh shell 中，以 jenkins 用户身份登录，一切正常。(如果我将 RVM 设置为使用 ruby​​ 1.9.3 ruby -v 返回 1.9.3 作为版本)
我为 Jenkins 使用 RVM 插件并将其设置为使用 1.9.3

Jenkins 为 RVM 输出: 捕获由“rvm use 1.9.3”产生的环境变量 $ bash -c 导出
$ bash -c "test -f ~/.rvm/scripts/rvm"
$ bash -c "test -f/usr/local/rvm/scripts/rvm"
[工作区] $ bash -c "source/usr/local/rvm/scripts/rvm && rvm use --install --create 1.9.3 && export > rvm.env"
使用/usr/local/rvm/gems/ruby-1.9.3-p0

---

但是，如果我以后想执行我的脚本，它会使用 ruby​​ 版本 1.8.7。

ruby 版本和环境的输出:

  + which ruby  
  /usr/bin/ruby  
  + ruby -v  
  ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]  
  + rvm info

问题:
如何让 Jenkins 改用 ruby​​ 版本 1.9.3？

Answer 1

我通过采购 rvm 解决了这个问题。
我将脚本更新为如下所示:

 #!/bin/bash
 source "/usr/local/rvm/scripts/rvm"
 rvm use 1.9.3
 rvm info

现在 rvm info 的输出是正确的。
最重要的是第一行和第二行。

rvm info 输出:

 ruby-1.9.3-p0:
