**Great** tool @xeroc - "This Reply is Powered by Piston"

**P**ython **I**mplemetation of  **ST**eem over **N**etwork ?

Your guide install piston as a user.  Does it work for all users if it is installed as root?

good tool!

hey @xeroc 

which folder does piston stores the keys etc ?

what the relationship between piston and steem-python?

I was wondering where does piston get the information? I've installed steemd but don't see a way of querying the blockchain... Something to do with BTS? Thanks!

just testing!

~/.local/bin/piston --help

Hi xeroc. Tks for the tip.

I ran this command and the message i get is
bash: /home/julio/.local/bin/piston: No such file or directory

According to
https://steemit.com/piston/@xeroc/piston ,
piston should have been installed in this location when I ran
pip3 install --user steem-piston

Any suggestions?

PS Sorry for being such a noob :-)

Until now.. okay i make it to get piston running but it tells me to provide an account.
What can i do ?

Hello fellas,

I am experiencing an annoying problem with Ubuntu while trying to install the Piston libraries.

After installing latest Phyton3 version I tried installing Piston via pip package manager and keep getting an error.

The error says Python requires version > 3 as if mine was lower.

Any idea how to fix this minor problem?

Thanks in advance.

I'm trying to run a python bot on Heroku that uses piston but I'm having trouble getting the imports correct.    From the project I cloned, there is an import:

     from piston.steem import Steem

this resulted in missing modules so I played around and finally got past that with:

        from steem.steem import * 

However, I am now getting a not found on steem.storage:
 
`Traceback (most recent call last):
  File "/app/.heroku/python/bin/piston", line 7, in <module>
    from piston.__main__ import main
  File "/app/.heroku/python/lib/python3.6/site-packages/piston/__main__.py", line 11, in <module>
    from steem.storage import configStorage as config
ModuleNotFoundError: No module named 'steem.storage'

    from steem.storage import configStorage as config
ModuleNotFoundError: No module named 'steem.storage'`

from the line:




subprocess.call(['piston', 'set', 'default_voter', steemAccountName])

Any help would be greatly appreciated.

For me, and maybe others on mac osx, I found that piston was installed to:

`~/Library/Python/3.5/bin/piston`

I would guess ``piston`` stands for a part of a steem-machine

https://github.com/xeroc/piston is obsolete and refers to https://github.com/xeroc/piston-cli

Could anyone recommend an alternative?

Very nice @xeroc. Will tinker a bit around with it when i have some spare time in the next days/weeks. -Posted from Piston-

HI there! I keep getting an error 
"Failed building wheel for scrypt" 
any idea how to resolve this?

@xeroc
I am having some major difficulties and have been researching and trying different things all day. However, unfortunately, I cannot find anything that works. 

I'm trying use an upvote bot where the first lines are: 
from piston.steem import Steem
from piston.steem import BroadcastingError

However, I get an error that says:
line 1, in < module >
    from piston.steem import Steem
ModuleNotFoundError: No module named 'piston'

I have the Python 3.6 installed as well as piston lib and cli. They are all updated and I have steem installed as well. I did everything through pip3 installation and homebrew.

Do you have any solutions?

Thank you,
Spencer Coffman

Hi very nice work, i try to run Piston on a Raspberry Pi it installed without problem, but it generates this when i try to add my key, any suggestions what's happening and how it can be solved ?

if i check the python version im running, with python -V

Python 2.79

if i do a install of python3 it says Python is already the latest version

I am having troubles install piston. I installed OpenSSL which helped with my install error, but now it installs and I am still unable to use the piston command. Is there something I am missing? I am using a bash terminal.

@originalworks

Version 0.1.5 has been released. It allows to configure your local
environment with `piston set <key> <value>`. You can get all
configuration variables with `piston set --help`.

As of Tue May  3 14:57:52 CEST 2016, the `develop` branch has some more
keys for customization available.
