1. enter container.

   Unknown macro: { stage("nodejs install") { // my Step sh 'npm config set registry https://registry.npm.taobao.org' sh 'npm config set sass-binary-site=http://npm.taobao.org/mirrors/node-sass' sh 'npm install' // not execute it. } stage("nodejs build") { sh 'npm run build' } stage('copy dockerfile') { input "Exit" } }

   }
   }

Status:

"npm install" or "npm build" is defined in my jenkinsfile.

when script run "npm config" In my jenkinsfile, the next step is "npm install", but it was not run, and my workflow is exit.
I use same jenkinsfile, I can receive success message if I am full luck.
The Error will be occur in other location, example after "npm install" or after "npm build" and soon.
