DEVICE_SERIAL=your_serial_number ./scripts/run_integration_test.sh throwing error

[Immanuel-Codoid]

I have followed all the steps mentioned in the repo, but while executing bundle install --path=bundler/vendor there were some errors in the execution and later when I ran the DEVICE_SERIAL=your_serial_number ./scripts/run_integration_test.sh, it throws DEVICE_SERIAL=serial_number : The term 'DEVICE_SERIAL='serial_number' is not recognized as the name of a cmdlet, function

Can you check and tell me what mistake I'm making here?

Help much appreciated @sorccu
