Angular 资产优化期间,网页包构建卡在Jenkins管道中

Angular 资产优化期间,网页包构建卡在Jenkins管道中,angular,jenkins,webpack,jenkins-pipeline,Angular,Jenkins,Webpack,Jenkins Pipeline,我使用webpack为我的Angular2应用程序进行开发和构建 在我的机器上构建我的源代码(webpack--profile--bail)时,webpack过程正常完成。 在my Jenkins CI pipeline中使用相同的命令时,该过程会在资产优化中永远陷入困境,可能是在使用html网页包插件之后或在使用提取文本网页包插件之前 以下是Jenkins管道中的步骤: container(name: 'webpack'){ git 'http://gogs/SMITE/smite-gui

我使用
webpack
为我的
Angular2
应用程序进行开发和构建

在我的机器上构建我的源代码(
webpack--profile--bail
)时,webpack过程正常完成。
在my Jenkins CI pipeline中使用相同的命令时,该过程会在资产优化中永远陷入困境,可能是在使用
html网页包插件之后或在使用
提取文本网页包插件之前

以下是Jenkins管道中的步骤:

container(name: 'webpack'){
  git 'http://gogs/SMITE/smite-gui-manager.git'

  echo 'Installing node modules'
  sh 'npm install'
  echo 'Building application to /dist'
  sh 'rimraf dist && webpack --progress --profile --bail --verbose'

  stage 'Canary release'
  newVersion = performCanaryRelease {}
}
所使用的容器包含所需的二进制文件,上述步骤应安装所有所需的
节点\u模块
,因此构建环境应相同


以下是不同的输出:

在我的机器上:

尽管使用了
--verbose
选项,但我无法获取任何其他日志,也无法找到修复错误的方法,知道吗

看来node的版本才是罪魁祸首

我运行了一个nodejs调试器,但没有找到任何其他信息,但我尝试使用不同版本的node进行构建,而且答对了

尽管看起来很奇怪,节点v6.9.0和v.6.9.1(yum repos中的npm依赖项)的行为却不一样(这只是一个小小的版本更改,拜托!)

在这两种环境上安装node v7.5.0就成功了
