I am using a Kivy as a Virtual Machine (in MAC OS). I am trying to install the python packages pycrypto and paramiko. Starting with pycrypto, I tried

pip install pycrypto Requirement already satisfied: pycrypto in /usr/local/lib/python2.7/dist-packages

but when I try to import it in python

>>> import pycrypto Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named pycrypto

In paramico, I get the following:

kivy@kivy-VirtualBox:~$ pip install paramiko
Collecting paramiko

Any suggestions?

  • maybe your default pip and default python are not related? Can you provide the output for `which pip` and `which python` (assuming you're on unix). Regarding the paramiko installation, it seems like you're trying to install the package in your system python, which, I assume has a lot of other packages installed in it. It seems like one of them requires six 1.5.2 and another >=1.6.0. You should really installs your dependencies in a virtualenv or compile python and run it in a different directory. Would that be possible? – nir0s Mar 06 '17 at 11:25
  • `kivy@kivy-VirtualBox:~$ which pip /usr/local/bin/pip kivy@kivy-VirtualBox:~$ which python /usr/bin/python` – Leonidas Souliotis Mar 06 '17 at 11:27
  • As I am new to the Unix and Python, I will try to do that! – Leonidas Souliotis Mar 06 '17 at 11:31

From the command line try:

python 2.7 import pycrypto

  • I tried, but I got the following `kivy@kivy-VirtualBox:~$ python import pycrypto python: can't open file 'import': [Errno 2] No such file or directory ` – Leonidas Souliotis Mar 06 '17 at 11:30
  • Are you specifying the Python Version number? From your log it does not appear you have – Darren Close Mar 06 '17 at 11:32
  • `kivy@kivy-VirtualBox:~$ python --version Python 2.7.6 ` – Leonidas Souliotis Mar 06 '17 at 11:34
  • You can't run it like that. do `python -c 'import pycrypto'` – nir0s Mar 06 '17 at 11:58
  • try to create a virtualenv (install virtualenv running `pip install virtualenv`) and create a virtualenv (`virtualenv my_env`). Then, activate the virtualenv by running `source my_env/bin/activate` and then try to pip install both pycrypto and paramiko. Let me know what happens. – nir0s Mar 06 '17 at 12:01
