Memory Error on install

[Ro-Ant]

I have installed Octoprint 1.3.5 and trying to install M33 Fio through the plugin manager.

I keep getting a memory error and then the system stops.

Any help would be amazing.

Based on this answer, you should be able to install the plugin if you set pip to not cache the file by using the --no-cache-dir flag.

So you set this flag in OctoPrint's settings > Plugin Manager > Settings > Additional arguments

Or manually run this command to install the plugin.
/usr/bin/python2.7 -m pip --no-cache-dir install https://github.com/donovan6000/M33-Fio/archive/master.zip

@donovan6000 - thanks so much for that. I had to run it via the command line as it kept stalling via the Plugins installer. However, now I can connect to the printer, but it connects only when 'Not using a Micro 3D printer' is enabled. Cycled the printers power and tried multiple times (as well as system reboots), but it didnt work.
