Import error even though module is installed - datafix - Jun-26-2017

Cant post my code because I'm new and it has links?
from bs4 import BeautifulSoup
from urllib.request import urlopen

url = "http://www.pythonforbeginners.com"

content = urlopen(url).read()

soup = BeautifulSoup(content)

print( soup.prettify())

#print(title) 
#>> 'title'? Python For Beginners

#print soup.title.string
#>> ? Python For Beginners

print(soup.p)

remove the links.
You'll be able to use them after you make a few posts

Error:
Traceback (most recent call last):
  File "/home/ubuntu/workspace/ex50/bin/firstsoup.py", line 1, in <module>
    from bs4 import BeautifulSoup
ImportError: No module named 'bs4'


Process exited with code: 1
Sorry for the multiple reply chunks- bs4 is definitely installed, so I don't know what I'm doing wrong. Apologize in advance for my newbie/idiot status!

You may have it installed, but apparently not for the version of Python you are running
please read: https://python-forum.io/Thread-Basic-Part-1-Python-3-6-and-pip-installation-under-Windows

type (from command line):
python --version

It's not installed when you get that message.
pip3 install beautifulsoup4
You execute with python3 firstsoup.py
Look at my Linux Python 3 environment,
and your script is wrong in newer BeautifulSoup has to call a parser and don't use urllib look at Web-Scraping part-1

I thought I was running v3 but in fact i was running v2. So I fixed that, reran it with v3 and got the same import error. Running on Cloud9- that shouldn't make a difference- do you think?

I use Cloud9 sometime myself.
Cloud9 has Python 2 and 3 installed,you have to pip3 install module,
and run code with python3 myscript.py

Thanks so much for all of the feedback. I was off on another project, but I'm back. I'll try out these suggestions and let you know how it worked.
@snippsat - Thanks! Your last post did the trick. Smile Smile
