Bug in installing about octoprint-webhooks

[jpisongithub]

Interesting, just found this... python-pillow/Pillow#4555 will try ssh into the pi then running "sudo pip install --no-cache-dir Pillow" and report back

Hmm, if you look at the very last word there is a 'MemoryError'. Seems your Raspberry Pi 0 ran out of memory trying to install 'Pillow' which is a package needed by the plugin. Seems to be an issue on smaller devices. Will look into if there is a workaround

Looks like it's a common issue. See these links for more guidance. It looks a little involved to fix, but basically, the Pi 0 doesn't have a ton of memory so it only allows a certain amount to things like temporary downloads (which is used by PIP to install the plugin and its dependencies). My plugin isn't the only one you'll run into issues with.

General Octoprint Issue

Installing another plugin with issues

[jpisongithub]

pip install command via SSH doesn't work due to another documented blunder

workaround follows using the octopi web interface...

went into settings and then to plugin manager
click the wrench in the upper right hand corner
scroll all the way down to the bottom

for additional arguments enter: --no-cache-dir
and check: Force the user of the --user flag with pop install

then install webhooks

then reboot the pi when prompted

works 👍 thanks for pointing me in the right direction!
