Solvedpm2 PM2 Start failing when using .JSON

PM2 fails to start a server ecosystem from a .JSON file. As an aside, I'm also unable to generate the ecosystem file using generate OR ecosystem.

I'm running on node 5.9.1 and PM2 1.1.3 (installed today). I've looked around forums and through GIT but didn't find my exact issue. My .JSON is attached.
LabMan.zip

The error I'm receiving is :
`C:\Users\MYUSER\AppData\Roaming\npm\node_modules\pm2\lib\CLI.js:461
Common.printOut(cst.PREFIX_MSG + 'App [%s] launched (%d instances)', data[0].pm2_env.name, data.length);
^

TypeError: Cannot read property 'pm2_env' of undefined

at Parser.Writable.write (_stream_writable.js:215:11)
at Socket.ondata (_stream_readable.js:536:20)`

I have tried uninstalling pm2 and reinstalling to no avail. There are two optional dependencies which say they've failed to install.

npm WARN optional Skipping failed optional dependency /pm2/ikt:
npm WARN not found: git
npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.11

Any help would be very appreciated!

Oh, one last thing... Since the generate/ecosystem commands fail for me I took an example of the .JSON from here : https://keymetrics.io/2014/06/25/ecosystem-json-deploy-and-iterate-faster/

TLDR Useful information for pm2-docker users googling this cryptic message (as I have been doing on and off all week)

TypeError: Cannot read property 'pm2_env' of undefined

This occurs because either the parsing of the process file itself failed, or contents of a process file is somehow incorrect, or a configured file cannot be read/written to

  • The process file (yml/json) is malformatted
  • The error_log or output_log directives point to locations docker cannot write to
  • The location of the script file is wrong (It will throw this error isntead of saying script not found)
  • error_log or output_log options refer to locations that docker cannot write to.
  • Your invocation of pm2-docker with a process file is incorrect( pm2-docker start path/to/process.yml versus pm2-docker path/to/process.yml) (the documentation isn't clear on this but failures have been noted)
