linux - Jenkins 无法运行程序 "ruby"没有那个文件或目录

Question

我正在从 jenkins 运行这项工作，但它经常失败......

但是我可以从 shell 运行一个相同的测试 ruby​​ 文件并且它工作正常

[root@jenkins01 etc]# su -c " source /usr/local/rvm/scripts/rvm && rvm use --install --create ruby-1.9.3-p484 && export > rvm.env ; ruby -v /tmp/test.rb" -s /bin/bash jenkins
Using /usr/local/rvm/gems/ruby-1.9.3-p484
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
hello

我认为它缺少这个文件..."/tmp/hudson4593249725887441871.rb"但作为用户“jenkins”我可以在/tmp 目录中创建文件...

知道问题出在哪里吗？

堆栈跟踪基本上意味着 Jenkins 启动的构建过程找不到 ruby​​ 可执行文件。

使用RVM Jenkins plugin如果你可以的话。它:

Runs your entire build (from SCM check out to post-build actions)within the context of an RVM managed environment of your choice (asopposed to your doing "source ~/.rvm/scripts/rvm && rvm foo@bar",which only affects your current shell)

If the Ruby/gemset youspecified doesn't exist on a slave that the build is running, it'll beautomatically installed and created (via rvm_install_on_use_flag)
