Clear environment variable ERL_FLAGS before obtaining the erlang version #29

Closed drobakowski closed 9 years ago

In cases where the name of a running node is set through the environment variable ERL_FLAGS (e.q. ERL_FLAGS="-sname test"), the command to fetch the erlang version will try to start a node with the same configs and fail. A local clear of ERL_FLAGS for that command will prevent this behavior.

Thanks for the PR. Makes sense to me to keep the env clean since we are just fetching the version. I'll merge it!
