如何解决错误：在运行Karma时产生Jenkins上的EACCES？
我已经设置了AWS Codepipeline。
该pipe道使用Git作为源，Jenkins进行testing，并使用EC2实例进行部署。
该项目是基于Angular Class的Angular Starter 。 因此，它使用Karma进行unit testing。
Jenkins服务在Ubuntu 16.04上运行。
Karma使用Headless Chrome进行testing。
问题是我目前在Jenkins上运行testing时遇到以下错误：
[31m07 05 2017 14:30:35.779:ERROR [karma]: [39m{ Error: spawn EACCES at exports._errnoException (util.js:1050:11) at ChildProcess.spawn (internal/child_process.js:319:11) at exports.spawn (child_process.js:378:9) at spawnWithoutOutput (/var/lib/jenkins/workspace/ExampleTask/node_modules/karma/lib/launchers/process.js:168:24) at Object.ProcessLauncher._execCommand (/var/lib/jenkins/workspace/ExampleTask/node_modules/karma/lib/launchers/process.js:76:21) at Object.ProcessLauncher._start (/var/lib/jenkins/workspace/ExampleTask/node_modules/karma/lib/launchers/process.js:33:10) at Object.<anonymous> (/var/lib/jenkins/workspace/ExampleTask/node_modules/karma/lib/launchers/process.js:19:10) at emitOne (events.js:101:20) at Object.emit (events.js:191:7) at Object.BaseLauncher.start (/var/lib/jenkins/workspace/ExampleTask/node_modules/karma/lib/launchers/base.js:42:10) at Object.j (/var/lib/jenkins/workspace/ExampleTask/node_modules/karma/lib/launcher.js:116:17) at Object.setTimeout.bind.j (/var/lib/jenkins/workspace/ExampleTask/node_modules/qjobs/qjobs.js:143:18) at ontimeout (timers.js:386:14) at tryOnTimeout (timers.js:250:5) at Timer.listOnTimeout (timers.js:214:5) code: 'EACCES', errno: 'EACCES', syscall: 'spawn' } 我已经做了一些研究，结果如下：
- 其他人也有类似的错误，但涉及到其他包
- 该错误可能与错误的权限有关
我到目前为止所尝试的：
- 检查/ var / lib / jenkins / workspace / ExampleTask的权限 – > result：owner是jenkins user
- 给jenkins用户root权限（我知道这是危险的，但我只是想尝试，如果它会工作） – >结果：错误仍然存在
- 允许jenkins用户使用sudo运行脚本 – > result：nvm，npm和节点没有定义; 我试图手动安装nvm，npm和节点，但得到了一个新的错误
permission denied /root/.nvm
npm日志文件输出如下所示：

看起来你正在使用Jenkins节点插件，它没有正确的权限来执行特定的任务，如果你可以尝试使用节点的基础安装，提供Jenkins用户sudo perms，然后使用像“sudo命令”这样的命令可以帮助你。
