Manually installed dependencies, port number error

[anuragparida]

• The application is supposed to handle its dependencies on its own and download the required modules, but-
  • 4 dependencies had to be installed manually before the process could start-
    • Cron - I had to run npm install cron because it was not downloaded automatically(see below)-
    • Twisted - I had to run pip install twisted manually because python socket_server.py produced module error(see below)-
    • Autobahn - I had to again run pip install autobahn for the same command python socket_server.py(see below)-
    • Serial - The serial module had to installed manually on my end (python read_serial.py)(see below)-
  • All these module errors must be addressed and files should be configured to get downloaded automatically.
• Even after I had installed all the dependencies, running python read_serial.py gave the following error about port number, and there was no documentation to troubleshoot it. (see below)-
