Yes, this is an old question, when I followed the commands above (THANK YOU) it helped me to realize that I was still missing something (lxml). Therefore, you will need to install both packages; "lxml" and "requests" using "pip install lxml" and "pip install requests".
1. First Find the directory where Python installed.
"C:\Program Files (x86)\Python36_64\Scripts\"
2. Make sure you open CMD "Run as Admin"
, and run the following commands:
3. Change the directory to Python folder:
cd "C:\Program Files (x86)\Python36_64\Scripts\"
"pip install lxml"
"pip install requests"
Hope this helps who else stumbled on this, just like me!
