Can't ./bin/cowrie start (cannot import name certificate_transparency)

[ogre2007]

There is my error. Ubuntu 14. I were doing all stuff by INSTALL.MD (except pip install --upgrade setup tools, becouse w/o it i cant install requirements.txt

[ogre2007]

As i can see, there is some problem with cryptography library (no x509 in dir(cryptography)) (or not, i'm not sure)

(cowrie-env)cowrie@ip:~/cowrie$ ./bin/cowrie start --debug

But as you can see, it installed properly. How can i solve this issue?

solved this, you should add upgrading pip commands in INSTALL.MD too..

[micheloosterhof]

Hi! It seems this requires a change in the INSTALL.md, reopening.
How did you solve this exactly?

pip upgrade pip?

[ttepatti]

Hey there! Just wanted to let you know I was able to solve this by appending --upgrade to the command for installing the packages in requirements.txt

Per the Debian Install Instructions:

pip install -r requirements.txt

should be changed to:

pip install --upgrade -r requirements.txt

This forced pip to upgrade all of the required packages before installing them, instantly fixing all of the errors I had.

[chitreshbb]

Cannot resolve the issue.

I'm trying to run it on AWS lambda with latest versions, it's still not working.
I'm using the latest pip version (pip 9.0.1 from /local/lib/python2.7/site-packages (python 2.7))
and using latest cryptography version "cryptography==2.1.4" as of 26th Dec 2017.

@R3e @ttepatti @micheloosterhof did you guys solve this?

[micheloosterhof]

@chitreshbb please open a new issue and post your exact error and steps you've followed to install the dependencies please.

[futex]

I have the same problem, have you solve it?

pip install --upgrade -r requirements.txt

Have no effect on my installation

[israellev]

I have the same issue and the upgrade did't solve it.

hi @israellev your issue does not seem to be related to Cowrie so we can't help you here. sorry.
