This post describes how you can fix the python error No module named 'winrandom'<\/code>. This is typically found when you are using the pyCrypto<\/code> or\u00a0coinbase<\/code> python module.<\/p>\n

<\/p>\n

What is the No module named ‘winrandom’ error<\/h2>\n

This python error may occur whenever you try and use a module that requires the winrandom<\/code> module. I found this problem occurring when I was importing the coinbase python module. This is because this includes and uses the pyCrypto<\/code> module.<\/p>\n

The full error log of the error is copied below.<\/p>\n

Traceback (most recent call last):\r\nFile \"C:\/dev\/test.py\", line 2, in <module>\r\nfrom coinbase.wallet.client import Client\r\nFile \"C:\\dev\\python35\\lib\\site-packages\\coinbase\\wallet\\client.py\", line 41, in <module>\r\nfrom Crypto.PublicKey import RSA\r\nFile \"C:\\dev\\python35\\lib\\site-packages\\Crypto\\PublicKey\\RSA.py\", line 78, in <module>\r\nfrom Crypto import Random\r\nFile \"C:\\dev\\python35\\lib\\site-packages\\Crypto\\Random\\__init__.py\", line 28, in <module>\r\nfrom Crypto.Random import OSRNG\r\nFile \"C:\\dev\\python35\\lib\\site-packages\\Crypto\\Random\\OSRNG\\__init__.py\", line 34, in <module>\r\nfrom Crypto.Random.OSRNG.nt import new\r\nFile \"C:\\dev\\python35\\lib\\site-packages\\Crypto\\Random\\OSRNG\\nt.py\", line 28, in <module>\r\nimport winrandom\r\nImportError: No module named 'winrandom'<\/pre>\n
This error occurs due to the way the imports works in the pyCrypto<\/code> library. In the next step I will describe how we can fix it.<\/p>\n
Fixing the\u00a0No module named ‘winrandom’ error<\/h2>\n
To fix the no module error we need to modify one of the files used by pyCrypto<\/code>. First we need to locate the directory Python3 is installed in.<\/p>\n
The most common location python is installed in is:<\/p>\n
C:\\PythonXX\\<\/pre>\n
Where XX is the version number. In my case I have installed python to C:\\dev\\Python35\\<\/code><\/p>\n
Once you have located the python directory you need to go into the Lib\\site-packages\\Crypto\\Random\\OSRNG<\/code><\/p>\n
The most common location this will be is:<\/p>\n
C:\\PythonXX\\Lib\\site-packages\\Crypto\\Random\\OSRNG<\/pre>\n
In my case this is: C:\\dev\\Python35\\Lib\\site-packages\\Crypto\\Random\\OSRNG<\/code><\/p>\n
Once in this directory you need to open the nt.py<\/code>\u00a0file\u00a0and find the line import winrandom<\/code>.<\/p>\n
This line needs to be changed from:<\/p>\n
import winrandom<\/pre>\n
to<\/p>\n
from . import winrandom<\/pre>\n
Once this has been done your modules using pyCrypto<\/code> will start working.\u00a0This resolved a relative import issue with this python module.<\/p>\n
If you have any questions or trouble finding where python is installed feel free to ask in the comments.<\/p>\n","protected":false},"excerpt":{"rendered":"
