trouble with node-report with node 12.14.1 on z/OS

[rpenny125]

• Version: v12.14.1
• Platform: OS/390 RS28 27.00 04 8561
• Subsystem:

Problem:

1. I'm trying to find tools that helps diagnose "apparent loops" in node on z/OS. Specifically, I'd like to be able to see the javascript stack, either from a running node process on z/OS, or from a system dump of the address space (the latter would be a "node" equivalent of the java tool jdmpview)
2. I think that the npm package node-report sounds like a useful tool, as it means I could issue "kill -USR2 " to force node to write out javascript information.
3. An old blog about IBM's node SDK suggests that node-report is "pre-installed" (https://developer.ibm.com/node/2017/03/10/node-report-now-available-ibm-sdk-node-js/)
4. when I try to use "-r node-report" on my node command line, this is the result:
   Error: Cannot find module 'node-report'
5. if I try to install node-report using "npm install node-report", the "make" fails (see below):
