I am trying to run a Python script using an Azure WebJob, and it works fine when I want to make requests and generate CSVs. I've successfully zipped all the packages that I need along with my script and have uploaded them to the Azure App_Data directory.
However, I also need to be able to connect to an SFTP site, and some of the packages required contain Python extension modules. When I run the script locally. it works fine. However, when I run on Azure, I get a message saying "ImportError: cannot import name _bcrypt"
Here is my script:
import sys, os
sys.path.append(os.path.join(os.getcwd(), "site-packages"))
import pysftp
import paramiko
hostname = 'host'
username='user'
password='pass'
port='port'
source = 'D:\\Home\\PunchData.csv'
destination = 'PunchData_Success.csv'
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname=hostname,port=port,username=username,password=password)
ftp_client=client.open_sftp()
ftp_client.chdir('uploads')
ftp_client.put(source,destination)
ftp_client.close()
Here is the full error message I receive:

It seems to fail any time a Python extension module is imported. I'm using a 32bit Python 2.7 environment on a Windows machine. I've read that for Azure functions, you need to utilize a Python wheel to replace Python extension modules, but I'm not sure how I would use a wheel for an Azure WebJob. Uploading the wheel to the WebJob directory doesn't solve the issue.
Any help would be much appreciated!
