unknown bus address error when starting the program.

Hi this is what I get when I type in node REPL,

var pidgin = require('pidgin').createClient();
Error: unknown bus address
    at createStream (/root/node_modules/pidgin/node_modules/dbus-native/index.js:24:26)
    at Module.module.exports (/root/node_modules/pidgin/node_modules/dbus-native/index.js:54:32)

Does this mean that I have something else to install as a dependency or something?

how do you launch it? session bus address is in DBUS_SESSION_BUS_ADDRESS, check that you have it in your system:

[vijaybritto]

Its not there! But I just did some googling and started the dbus-launch command. And the response was

DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-PHGuFCHAqA,guid=8b6e916d0b5b896d2a07415255719f3f
DBUS_SESSION_BUS_PID=234

But still it doesnt work even after running this command The same unknown bus address error comes up

[sidorares]

do you have same error even if DBUS_SESSION_BUS_ADDRESS is set?

[vijaybritto]

yeah

Should I copy that DBUS_SESSION_BUS_ADDRESS and set in the system path manually?

[vijaybritto]

Its working now. But I get an other error like

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: write EPIPE
    at errnoException (net.js:905:11)
    at Object.afterWrite (net.js:721:19)

For the reference of others (e.g. people who might be running into the same issue in Travis CI), the man doc recommends using dbus-launch and eval:

http://linux.die.net/man/1/dbus-launch

eval "$(dbus-launch --sh-syntax)"
