AttributeError：在Ubuntu中运行Python tweepy脚本时解码错误

Question

I have a Python 3.5 script which essentially is a Twitter scraper that collects tweets using the tweepy package and its StreamListener function.

Now my script runs perfectly within the Command shell but when I try to run it on the Ubuntu environment of my server I receive a decoding error.

   File "/usr/lib/python3/dist-packages/tweepy/streaming.py", line 445, in filter
self._start(async)
   File "/usr/lib/python3/dist-packages/tweepy/streaming.py", line 361, in _start

   File "/usr/lib/python3/dist-packages/requests_oauthlib/oauth1_auth.py", line 1                                                                                                             4, in to_native_str
return string.decode('utf-8')

AttributeError: 'str' object has no attribute 'decode'

This makes sense because you can't decode a string which already is a string. But my question is how I can solve this issue because this is an error occuring within a package?

Answer 1

It looks like the problem comes from requests-oauthlib , you are running an old version of it, and the problem seems to have been fixed since 4.0.1 .

Upgrade your system (the packaged version with Ubuntu 16.10 is 7.0):

sudo apt update && apt upgrade

Or install using pip:

sudo pip3 install requests-oauthlib
