I tried installing pubnub. I went through the website of pubnub and did as it was told on the website. https://www.pubnub.com/blog/2015-07-22-getting-started-with-raspberry-pi-2-and-pubnub-in-python-programming-language/

While I tried to do pip install pubnub (sudo pip install pubnub), the following error occured. I can't install it no matter how much I try.

Here is the error:

Exception:
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in main
    status = self.run(options, args)

    req, link, "connection error: %s" % exc, url,
TypeError: __str__ returned non-string (type Error)

Storing debug log for failure in /home/pi/.pip/pip.log

Does anybody have any solution so that I can install it?

Can you check your Raspberry pi time. Sometimes it so happens when your system time is inaccurate the pip installation fails. I have faced this issue once.

You may check the articles below on how to set the time. How to force NTPD to update date/time after boot?

Hope this helps.
