Why fSpy addon can't be enabled I am trying to install the fSpy add-on for Blender. I've downloaded it as a .zip file and went to user preferences to install it. However, it does not show up in any list of add-ons in user prefs.


When I checked the console it repeatedly shows the following:

Modules Installed () from '/Users/lihechen/Downloads/All Files/Plugins/Blender/fSpy-Blender-master.zip' into '/Users/lihechen/Library/Application Support/Blender/2.81/scripts/addons'


But nothing shows up.
Can anyone please help? I'm using Blender 2.81
New answer (after getting feedback in the comments):
The file you are trying to install is the wrong one (i.e. the repository downloaded as a zip file). Try with the release file instead.

Old answer:
I suspect that it is in fact installed but not showing up in the list because it is not enabled yet (your screenshot is only showing enabled add-ons).

First, uncheck the checkbox that says "Enabled Add-ons Only" to be able to find the add-on, then check the checkbox for the add-on to enable it.
