Jenkins does not recognize command sh?

Question

I\'ve been having a lot of trouble trying to get a Jenkinsfile to work. I\'ve been trying to run this test script:

#!/usr/bin/env groovy
node {
    stage(\'

In order to fix this issue, in case that you can't delete the PATH global property from "Manage Jenkins -> Configure System", you should add the following step:

withEnv(['PATH+EXTRA=/usr/sbin:/usr/bin:/sbin:/bin'])

Like following: for Scripted Pipeline:

node {
  stage ('STAGE NAME') {
    withEnv(['PATH+EXTRA=/usr/sbin:/usr/bin:/sbin:/bin']) {
      sh '//code block'
    }
  }
}

or for Declarative Pipeline:

pipeline {
  agent {
    label 'master'
  }

  stages {
    stage ('STAGE NAME') {
      steps {
        withEnv(['PATH+EXTRA=/usr/sbin:/usr/bin:/sbin:/bin']) {  
          sh '''
            //code block
          '''
        }
      }
    }

I hope this helps. I also struggled a lot to find a solution for this.
