Similar to @TortuePatate, I solved it by running: geth --datadir=".embark/development/datadir" --password config/development/password account new Embark should probably run this before account list

Hi there, I’ve got exactly the same problem but I’m running on Mac OS X. I tried to tweak the config/blockchain.json file on lines 13, 24 and 35 (“account”) but to no avail.

I’ve got an account properly set up on geth but it is not recognised when using embark.

Oh lol, try sudo npm i -g embark
