bs4.Feature Not Found Error Message

[charfeldman]

Hi Alteryx Community,

Has anyone seen this error message before when running an Analytic App which uses python?

The app works on my own desktop but when a friend tried to run it, he got the error message shown below. I am wondering whether he needs to download more packages that I already have downloaded but forgot to include in the Python script. The python script embedded in the Analytic App is as follows:

#################################
# List all non-standard packages to be imported by your
# script here (only missing packages will be installed)
from ayx import Package
from ayx import Alteryx
Package.installPackages(['requests'])
Package.installPackages(['bs4'])

#################################

#################################
# Parse the html file

#################################
# Format the parsed html file
strhtm = soup.prettify()

#################################

#################################

#################################

list_rows.append(clean_text)

hey @charfeldman 

I believe you're right - 
It has issue with this line: clean_text = BeautifulSoup(str_cells,"lxml").get_text()

Im not as familiar with BS4 as i'd like to be, but i believe lxml has to be imported too, so try adding:
Package.installPackages(['lxml'])

At the start of your code.

Let me know if this helps!

EDIT: from looking at some documentation on lxml, you may also need this too:

Package.installPackages(['html5lib'])
