Thanks for your reply, installation went ok

"pip3 install --user steem-piston"

but when i try to do "piston addkey" it gives this error

pi@raspberrypi:~ $ piston addkey
Traceback (most recent call last):
File "/usr/local/bin/piston", line 5, in module
from pkg_resources import load_entry_point

raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pycrypto>=2.6.1

When i check the python version its 2.7.9

When i tr to install python 3 it says latest version already installed

Which distro are you running on your pi ?

PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)"
NAME="Raspbian GNU/Linux"
VERSION_ID="8"
VERSION="8 (jessie)"

May be try this to force reinstall of pycrypto:
sudo apt-get install libffi-dev libssl-dev
pip3 install --user cryptography --force-reinstall

1 upgraded, 3 newly installed, 0 to remove and 134 not upgraded.

Do you want to continue? [Y/n] y
Abort.

after that still same error when running "piston addkey"

Any suggestions ?

(i just send this error to @xeroc the maker of piston)

Also found someone with the same error code and he suggest to

git clone https://github.com/xeroc/piston

but the given solution result in the same error
