Extension Installer Error

[Joe Percival]

 I have tried using the extension installer following the guidance from the github wiki on an extension package created by modifying the mem extension example.  I do not understand the error message I am getting.  Can someone please explain where I've gone wrong?
My extension package is a zipped directory named weewx_snow which contains install.py, a bin directory and a skins directory.
here is the error message I am getting:

raise InstallError("Unable to install from '%s': no common path (the extension archive contains more than a single root directory)" % extension_path)
weecfg.extension.InstallError: Unable to install from '/home/pi/Downloads/weewx_snow.zip': no common path (the extension archive contains more than a single root directory)

I know you outlined your zip structure but it wasn't 100% clear to me. I package in tgz format not zip but the structure I have in my tgz file is:

name
 |
 -- install.py
 |
 -- readme.txt
 |
 -- changelog
 |
 -- bin
 |   |
 |   -- directories/files to go in $BIN directory
 |
 -- skins
     |
     -- directories/files to go in skin directory


where name is the common name of the extension/driver etc

Alternatively, post your zip.

yes.  though I have taken out the readme and changelog for the time being.

I have found the problem.  I created the zip on a Mac and it created a second directory inside the archive called _MACOS.  That was confusing the installer.

Deleting that directory allowed the installer to proceed (and churn up the next layer of bugs).

Thanks,

joe

That would do it, my understanding of the extension installer is that in the archive everything needs to be under a single top level directory.
