从jenkins运行时出现NPM问题

Question

我目前面临着一些与gradle/NodeJS相关的问题。我所做的是通过在我的gradle脚本中编写以下代码来使用Node插件：

apply plugin: 'com.moowork.node'

dependencies {
    classpath 'com.moowork.gradle:gradle-node-plugin:0.12'
 }

现在，当我尝试通过运行以下命令从终端(CentOS)运行install npm命令时：

gradle npmInstall

它运行得非常好，并且安装了所有需要的软件包，而当我从Jenkins (在centos中安装的Jenkins)运行相同的命令时，我得到了以下错误消息：

:npmInstall FAILED
 FAILURE: Build failed with an exception.

* What went wrong:
  Execution failed for task ':npmInstall'.
  > A problem occurred starting process 'command 'npm''

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task 
':npmInstall'.
at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:69)

Caused by: org.gradle.process.internal.ExecException: A problem occurred starting process 'command 'npm''
at org.gradle.process.internal.DefaultExecHandle.setEndStateInfo(DefaultExecHandle.java:197)

Caused by: net.rubygrapefruit.platform.NativeException: Could not start 'npm'
at net.rubygrapefruit.platform.internal.DefaultProcessLauncher.start(DefaultProcessLauncher.java:27)

有没有人能帮帮我。我不知道我做错了什么。如果尝试运行以下命令，我也会收到相同的错误消息：

gradle npm_run_build_prod 

而同样的命令列表也适用于我本地的windows jenkins。
