【问题描述】：

我正在尝试在 Jenkins CI 中的 Ubuntu 12.04 机器上运行 karma 作为一项繁重的任务。我遇到的问题是 karma 不会打开 Chrome 并给出以下错误：

我已经设置了 CHROME_BIN=/opt/google/chrome 并且似乎找到可执行文件没有问题。

我采取的其他方法（均不成功）是： -> 创建 shell 脚本以使用标志 --user-data-dir 以 root 身份打开 chrome -> 将所有 chrome 文件复制到 jenkins 子目录 /home/jenkins/opt/google/chrome -> 将 /opt/google/chrome 中所有 chrome 文件的所有权更改为 jenkins

另一个奇怪的是，当我以 jenkins 用户身份登录机器时，chrome 可以正常运行测试。

如果我需要提供更多信息，请告诉我。谢谢

【问题讨论】：

我遇到了完全相同的问题（包括以 jenkins 用户身份登录并成功运行，包括为 bin 设置路径），但在我的情况下它是 firefox。你在这方面有没有成功。如果是这样，我建议发布我很乐意 +1 的答案。

【解决方案1】：

我遇到了同样的问题。为 Jenkins (https://wiki.jenkins-ci.org/display/JENKINS/Xvnc+Plugin) 安装 xvnc 插件后，问题消失了。

【讨论】：

这对我不起作用。我已经有了它，甚至尝试过卸载安装。虽然我的业力运行正常，但我真的更希望业力开始工作。您使用的是 karma run 还是 karma start ？ Ubuntu ?
哦。必须在构建配置中勾选 xvnc 选项。这应该是正确的答案。

【解决方案2】：

对我来说，这是对 karma start 与 karma run 的误用。您需要运行 karma 服务器，并在 jenkins 作业中使用 karma run。请参阅我的问答here。
