Newbie unable to deploy to github ERROR Deployer not found: [object Object]

[Tony Su]

Before the main question 2 other questions

1. Am wondering how so many guides describe deployeing to branch Main and that somehow can be deployed on a github webserver? I thought only files deployed to branch gh-pages can be deployed by the github webserver.

2. When running a hexo-deploy, and specifically to github, does the target repository on Github have to already exist? Some guides I read say to create the github repo first before deploying, others don't mention that step.

Now,

My main question...

Following mostly the guide at the following URL with changes I'll describe...

https://gist.github.com/btfak/18938572f5df000ebe06fbd1872e4e39

The changes I've made to _config.yaml (excerpts)(everything else in the file is default)

# Site

title: Hexo Demo

subtitle:

description: A blog site

keywords:

author: TZU

language:

timezone: America/Los_Angeles

# URL

## If your site is put in a subdirectory, set url as 'http://yoursite.com/child' and root as '/child/'

url: http://putztzu.github.com/hexo-demo

root: /hexo-demo/

permalink: :year/:month/:day/:title/

permalink_defaults:

# Deployment

## Docs: https://hexo.io/docs/deployment.html

deploy:

  type:

          type: git

          repo: putztzu.github.com/hexo-demo.git

          branch: gh-pages

The command

# /usr/local/bin/hexo deploy

ERROR Deployer not found: [object Object]

Not in the above reference, but based on another source I also ran the following script to install these components individually

npm install hexo-generator-index --save && \

npm install hexo-generator-archive --save && \

npm install hexo-generator-category --save && \

npm install hexo-generator-tag --save && \

npm install hexo-server --save && \

npm install hexo-deployer-git --save && \

npm install hexo-renderer-marked@0.2 --save && \

npm install hexo-renderer-stylus@0.2 --save && \

npm install hexo-generator-feed@1 --save && \

npm install hexo-generator-sitemap@1 --save

Assistance and insight greatly appreciated, Thx.
