Cant Install pyd plugin

[terrymedford]

I have followed the instructions on the volumio site https://volumio.github.io/docs/Plugin_System/Plugin_System_Overview

but when i do volumio plugin install

i get the following error message

/bin/mv: target '/tmp/plugins/pydpiper.zip' is not a directory child_process.js:644 throw err; ^ Error: Command failed: /bin/mv *.zip /tmp/plugins/pydpiper.zip /bin/mv: target '/tmp/plugins/pydpiper.zip' is not a directory

I am using Volumio 2.522.

any help would be gratefully received.
