gmail-parser.py failure

How about a shot in the dark

sudo apt-get install python-feedparser


Cheers!!!

As stated above, I actually wrote the how to's on this thing..

Yes, it and python3-feedparser is installed

[PackRat]

Doesn't happen to be a python2-feedparser used by your other installs, does there?

And I get identical error messages using python, python2.7 and python3.5 in

Code Select Expand

python /home/location_of_file/gmail_parser.py yourusername yourpassword

running the script on Void linux, python-feedparser version 5.2.1

[VastOne]

Nope..  Just the latest SID version..  5.1.3-3

[jedi]

not that it's any comfort, but mine is the exact same way. same error, tried all of above and no joy...

[hakerdefo]

I think I've figured this one! Warning, I've been proved wrong before 
VastOne, Time has come to update this script cause changes made in python and urllib has rendered it obsolete! Are you sure gmail-parser.py is working on other Debian Sid installs? Anyways here is the modification of gmail-parser.py that should hopefully work with python 3 & co.

You will need to add your Gmail username and password to the following fields in the script before using it,

Code Select Expand


username = "your_gmail_username_here"
password = "your_gmail_password_here"


Save it somewhere in your $PATH and call it like this from conky,

Code Select Expand


execpi 600 /path/to/gmail-parser.py


Of-course you will have to replace '/path/to/gmail-parser.py' above with the actual path where you have saved the script.

Absolutely untested as I don't have python 3 on this box! Might blow up your computer! You've been warned! Good luck!

I get an error running it in a terminal -

Code Select Expand

Traceback (most recent call last):
  File "./gmail-parser.py", line 5, in <module>
    import feedparser         # For parsing the feed
ImportError: No module named 'feedparser'

@vastone - python-feedparser the only depndency?

[hakerdefo]

Hi there PackRat,
You will need 'python3-feedparser' for the modified script I've posted. So just do,

Code Select Expand


sudo apt-get install python3-feedparser


And things should be fine!

Cheers!!!

Ok, I get a whole bunch of new errors -

This system is Void linux - I can check your script on my Debian system once the crew heads for Girl Scouts and the desk is free.

@vastone - you have a link to your #! HowTo? I didn't see it recreated here. Void is crazy minimal so I need to make sure I have the packages installed - there no recommneded packages with Void just hard dependencies (wget isn't even part of the default install - distro is bat-shit crazy in some ways).

[VastOne]

There is a How To on #! but I'll be damned if I can find it there..

The earliest references I have found of a How To on this by me is here on the Ubuntu forums in a thread about conky

The only requirement though is and has always been python-feedparser, nothing else

[hakerdefo]

@PackRat @VastOne
You've got following installed?

Code Select Expand


python3-openssl
python3-requests
python3-urllib3


Install if missing and re-run the script!

Cheers!!!

Still the same...

Folks, AFAIK there's currently something libssl breaking python. Might be that driving you mad?
