【问题描述】：
我已经设置了一个 AWS Codepipeline。
管道使用 Git 作为源，使用 Jenkins 进行测试，使用 EC2 实例进行部署。
该项目基于Angular Starter by Angular Class。因此，它使用 Karma 进行单元测试。
Jenkins 服务在 Ubuntu 16.04 上运行。
Karma 使用 Headless Chrome 进行测试。
问题是我目前在 Jenkins 上运行测试时遇到以下错误：
[31m07 05 2017 14:30:35.779:ERROR [karma]: [39m{ Error: spawn EACCES

我已经做了一些研究，得出以下发现：
- 其他人也有类似的错误，但与其他软件包有关
- 错误可能与权限错误有关
到目前为止我所尝试的：
- 检查 /var/lib/jenkins/workspace/ExampleTask 的权限 -> 结果：所有者是詹金斯用户
- 给jenkins用户root权限（我知道这很危险，但我只是想试试它是否可行）->结果：错误仍然存在
- 允许 jenkins 用户使用 sudo 运行脚本 -> 结果：未定义 nvm、npm 和节点；我尝试手动安装 nvm、npm 和 node，但出现新错误
permission denied /root/.nvm
