gnuradio doesn't work after install, "No schemas installed" error

[jeremyherbert]

Hi,

I'm not sure if this is just me, but I just ran the following two commands:

brew install uhd
brew install gnuradio

There doesn't appear to be any errors in the output, but when running gnuradio-companion after installing, I get the following error:

$ gnuradio-companion

gsettings-desktop-schemas is correctly installed:

Has anyone else come across this issue? I'm running the latest Catalina.

What does gsettings get org.gnome.desktop.interface gtk-theme say?

whoops, sorry, I replied in the wrong place. Moving to here:

Nothing unusual there. How about gsettings --schemadir /usr/local/share/glib-2.0/schemas list-schemas --print-paths?

Since that succeeded, it looks like your glib is looking in the wrong directory for some reason.

What's the output of otool -L $(which gsettings)?

[jeremyherbert]

aha! that was it. I have anaconda installed, and it seems there was a separate gsettings in the path. Removing it from the path solved my problem. Thanks for all your help!
