Pip 19.0.3 NOT installing?


So on using this Line to update ;

~/oprint/bin/pip install https://get.octoprint.org/latest

I get this message at the end of it;

You are using pip version 19.0.1, however version 19.0.3 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

HOWEVER - this is what happens when attempting to remedy error message ??

pip install --upgrade pip

-bash: pip: command not found


pip is located in /home/pi/oprint/bin which is not a part of the default $PATH.
Just go to /home/pi/oprint/bin and type:

sudo ./pip install --upgrade pip


Uh, no.

OctoPrint itself manages the pip version. You are encouraged to leave it alone.


thanks - thats worked !!


I do understand that - BUT as Octoprint did NOT 'work out of the box' for me I had to do what I could do make it work - it now works 80 %


Personally, I have never typed that line into a Terminal ever and I've used OctoPrint for over a year now. The bundled Software Update plugin has always worked for me.

If you're working on a fork of OctoPrint, I can see running that possibly against your own clone of your own fork. Or if you're developing OctoPrint with the authors and you need to follow a particular branch they're working on for testing, I can see doing that.

In rare cases when leftover eggs are lying around then pip install --force-reinstall https://get.octoprint.org/latest (having activated the virtual environment first) would be in order.

And yet, this isn't really the normal usage case. I don't believe that it's a good idea to run pip with sudo, for what it's worth but I'm really not the expert here. I just know that foosel herself mentioned this before.

Why not describe what the problem was before you began trying to fix it?

Upgrade pip manually?

Thanks for your reply, installation is now all OK - the only thing NOT working is the Raspicam streaming. All I get is the ‘Webcam stream loading’ forever BUT will test with a USB webcam when I get one. Just haven’t had time of late so will report back soon as I’ve tried a different camera option


You might want to mention your browser. I know that the IE browser isn't happy with the <img /> tag approach that OctoPrint uses.


Thanks - looks like my RaspiCam is dead (unless I messed settings up)- Logitech C270 USB worked straight away
