How to install extension from the command line?

Documentation

I’m diving into Blender’s new extension system that is replacing addons, mostly because I need to use python wheels. Anyhow, I’d like to add a line to my make script that installs the extension after I’ve finished building it. I’m trying to figure out the right syntax to use. According to the docs, I think I need something like

blender --command extension install-file -r REPO --enable extension/kitfox_my_extension-1.0.0-windows_x64.zip

The problem is, I have no idea what the REPO is supposed to be and the documentation doesn’t provide any help. If you leave it out, it refuses to install. This is a just a zip file in a local directory that my script has just built - what should I put for the REPO?

I’m not in front of my computer, so I may be wrong.

But I would run the repo-list sub-command to see which repositories you have available, and pick the one you need.

Maybe the person who asked the question gave up, but I verified it instead.

First,
The value obtained by the repo-list command is

blender_org:
    name: "extensions.blender.org"
    directory: "C:\\Users\\<USER>\\AppData\\Roaming\\Blender Foundation\\Blender\\4.2\\extensions\\blender_org"
    url: "https://extensions.blender.org/api/v1/extensions/"
user_default:
    name: "User Default"
    directory: "C:\\Users\\<USER>\\AppData\\Roaming\\Blender Foundation\\Blender\\4.2\\extensions\\user_default"
    source: "USER"
system:
    name: "System"
    directory: "C:\\Program Files\\Blender Foundation\\Blender\\4.2\\extensions\\system"
    source: "SYSTEM"

to be.

I had already added the repository on the Multiple Preferences screen,
It was not showing up.
I also tried repo-add and it added it but it did not show up in this repo-list.

On the other hand, when I ran the following code

import bpy

def check_repositories():
    prefs = bpy.context.preferences
    for repo in bpy.context.preferences.extensions.repos:
        print(f"ID: {repo.module}")
        print(f"  Name: {repo.name}")
        print(f"  Path: {repo.directory}")
        print(f"  Remote: {repo.remote_url}")
        print(f"  Source: {repo.source}")
        print(f"  module: {repo.module}")

check_repositories()

You will receive the same response as in the Preferences screen(Blender UI) as shown below.


ID: blender_org
  Name: extensions.blender.org
  Path: C:\Users\<USER>\AppData\Roaming\Blender Foundation\Blender\4.4\extensions\blender_org
  Remote: https://extensions.blender.org/api/v1/extensions/
  Source: USER
  module: blender_org
ID: user_default
  Name: User Default
  Path: C:\Users\<USER>\AppData\Roaming\Blender Foundation\Blender\4.4\extensions\user_default
  Remote:
  Source: USER
  module: user_default
ID: system
  Name: System
  Path: C:\blender\stable\blender-4.4.0-stable.<BUILD_ID>\4.4\extensions\system
  Remote:
  Source: SYSTEM
  module: system
ID: ksyn_repo
  Name: ksyn_repo
  Path: C:\Users\<USER>\AppData\Roaming\Blender Foundation\Blender\4.4\extensions\ksyn_repo
  Remote: file:///D:/.../blender%20scrpt/.ksyn_repo/index.json
  Source: USER
  module: ksyn_repo
ID: ksyn_repo_001
  Name: ksyn_repo.001
  Path: C:\Users\<USER>\OneDrive\documents\aaa\
  Remote:
  Source: USER
  module: ksyn_repo_001

Since the install-file in the command is “usable in the list output by the command”,
Probably a bug in repo-list and install.
