Invalid requirement: '<<<<<<< HEAD'
Getting this: http://i63.tinypic.com/2lm8e4x.png
When trying to run: pip install -r requirements.txt
on a first install. Used to work fine. Using Python 3.6.3
Fixed it myself by cleaning up the 'requirements.txt file' and changing the contents to:
decorator==4.0.10 PyYAML==3.12 wheel==0.24.0 appdirs==1.4.3 arrow==0.10.0 backports-abc==0.5 certifi==2017.4.17 chardet==3.0.4 idna==2.5 praw==5.0.0 prawcore==0.11.0 python-dateutil==2.6.0 requests==2.18.1 shreddit==6.0.7 six==1.10.0 tornado==4.5.1 update-checker==0.16 urllib3==1.21.1
No idea why there were duplicate additions in the .txt file as well as invalid characters. Maybe this used to work but it didn't seem to work with Python 3.6.3 as stated so I just removed those and cleaned the invalid characters until it completed without error.
Edit: Didn't mean to close this.
This is still a problem.
For what it's worth, pull request #103 fixes this. You can also manually overwrite requirements.txt with the fixed file.
I had this issue and the fixed file from "ghost commented on Oct 18, 2017" fixed the issue.
