Cannot run Volttron Instance

Question

I am working on Volttron and created a couple of agents. Today all of a sudden volttron instance fail to start. Earlier everything was working fine and I was able to start volttron and test the agents.

This is the error message i am getting now.

(volttron) nitin@346Z4Y2:~/volttron$ ./start-volttron

Please execute from root of volttron repository.

Earlier I was getting folllowing messages-

(volttron) nitin@346Z4Y2:~/volttron$ ./start-volttron

PID file exists but process is not running. Removing old VOLTTRON_PID file

Please execute from root of volttron repository.

(volttron) nitin@346Z4Y2:~/volttron$ vcfg

volttron-cfg needs to be run from the volttron top level source directory

I don't know what happened suddenly that I cannot start the Volttron Instance.

Answer 1

Issue fixed after copying missing volttron files. @Craig Many thanks

Answer 2

This issue was created when transferring a copy of the repository from one instance to another. The user missed a vital directory. Lesson learned from this is to clone a fresh new copy of VOLTTRON or make sure you get all of the directories when copying from one system to another!
