I get postactivate in the /bin/ folder, but I have no idea what I'm doing once inside that file. I've tried to Google this to no avail!
ClientException: ffmpeg/avconv was not found in your PATH environment variable
Forums
How do I add avconv to my PATH Environment Variable?
What command is triggering that error? Is it happening when you workon your virtualenv? Or at some other point?

I'm running a Discord bot that utilises youtube_dl to download, and then either ffmpeg or avconv to play. I can download the video using a preset command, but when it reaches the 'play' element, this is triggered.
Where are you running the code? Is it in a console, a web app or a scheduled task?
I have a bot which I run through bash console. The input comes externally, from Discord- but that isn't the issue. I believe the issue is that avconv is not found, and it is a requirement for this to work.
avconv is installed in /usr/bin and that should pretty-much always be on the PATH. You could try using the full path to see if that changes anything.
Hi Glenn, I can't seem to see avconv in either my /usr/bin or my /virtualenv/bin. Any thoughts?

You're not looking it the right place. Neither of those is /usr/bin. The picture is of /home/kitLUL/bin and, unless you or a package you install specifically puts it into your virtualenv, it's not going to be there. It is installed for all users of PythonAnywhere as /usr/bin/avconv.
Ah- understood, cheers. I'm still relatively new to using PythonAnywhere- how would I use the full path in this context?
To add it to the path from a bash console, you'd run this:
export PATH=/usr/bin:$PATH
That would only take effect in the console where you typed it.
That said, it would be really weird if /usr/bin wasn't on your path. What do you get if you run which avconv just before you run the Discord bot? It should print out the location of the command, /usr/bin/avconv
Hi again Giles.
It prints as above, /usr/bin/avconv.
Upon trying to play audio from a Youtube video, I am met with this:
23:47 ~ $ export PATH=user/bin:$PATH
23:48 ~ $ python3.6 Ava/Ava.py

Apologies- I've fixed the issue.
There was an argument within youtube_dl I wasn't aware of that I didn't have flagged, so it was searching for ffmpeg, as is apparent from the log I linked- I was very tired. Thank you for your help!
Ah, glad you worked it out, especially given that it wasn't giving you the most helpful of error messages!
