I'm on OS X.

Following this tutorial https://medium.freecodecamp.org/from-what-is-blockchain-to-building-a-blockchain-within-an-hour-4e738efc819d

I ran into some trouble where the author says to run geth personal.newAccount() in the geth console:

Creating a Blockchain The following creates the Blockchain, with the maxpeers command is set to 0 to disable the network. mkdir eth-data geth --datadir eth-new genesis.json init eth-new/genesis.json --networkid 123 --nodiscover --maxpeers 0 console In the geth console, type the following to make a new account and create a new password by typing in whatever you want. You will have to type your new password twice. personal.newAccount()

I didn't see a console cursor so plugged that in the command line, followed by a password. 

geth personal.newAccount()\npassword

Now when I try to run any geth command I get this:

geth:129: command not found:password.

I deleted with brew uninstall, reinstalled, same problem. I killed all processes and looked for a config file in a variety of places. 

Any thoughts on how to start over or fix this problem?

  • Long shot, but I'd check your OS aliases, my guess is that `geth` alias got messes up. Aliases are usually loaded at initialization of your shell so look in `.bash_profile` or `.bashrc` in your home directory. – Pedro Lobito Feb 09 '18 at 11:48

Just run this command:

geth personal.newAccount('your_password')

In my case, the reason was low memory. I tried running on a node with 0.5 GB and later one with 1 GB. It consistently failed with the following message on 0.5 GB node.

> personal.newAccount()
Password: 
Repeat password: 
Error: Post http://myhostname:8545: EOF

At the same time of above error, geth running on that node crashed with just a single work on stdout: Killed.

Increasing memory to 1 GB fixed the issue.
