Karma无法使用Jenkins和Ubuntu 12.04启动Firefox

Question

我已经设置了一个应该运行Firefox的Jenkins作业.与Jenkins用户一起登录Ubuntu,我可以毫无问题地手动启动Firefox.但是,当我在Jenkins工作时,我得到:

[EnvInject] - Loading node environment variables.
Building in workspace /var/lib/jenkins/jobs/cbx4-ci/workspace

[31mERROR [launcher]: [39mCannot start Firefox

[32mINFO [launcher]: [39mTrying to start Firefox again.
[31mERROR [launcher]: [39mCannot start Firefox

如您所见,我已将环境变量注入指向Firefox.

一些有用的版本号,如果这可以帮助:

Jenkins 1.546 NodeJs 0.10.24 Karma 0.10.9

编辑:

可能很高兴知道我必须为jenkins用户做一个操作,以便能够首先运行firefox.作为我的主要用户,我必须让其他用户通过执行来启动Firefox xhost +local:.没有它,jenkins用户不断收到以下错误.

虽然这可能是我解决的一个单独的问题,但它可能会在我问的问题上发生,所以我觉得重要的是添加这个细节.

Answer 1

得到它了.事实证明,问题源于对如何首先运行业力的误解.

Jenkins任务正在进行karma start,autowatch设置为true.相反,我在rc.local中启动了带有autowatch false的业力(脚本在启动时运行),然后执行Jenkins任务karma run.这完全解决了这个问题.

编辑:安装xvnc插件,并激活它以构建karma开始和业力运行.

编辑:当我升级到14.04时,问题又回来了.修复是为了确保构建中注入的环境变量指向X11版本.

FIREFOX_BIN=/usr/bin/X11/firefox
CHROME_BIN=/usr/bin/X11/google-chrome
