Unable to authenticate, need: Basic realm="GitHub Package Registry" when trying to publish npm package to github - github

Question

I am currently trying to publish a package to the Github registry.
The package is generated code, although this should not really matter here. The important thing is that I have the following:
The package.json file contains:
{
"name": "#company-name/repository-name",
"version": "v1.7.0",
"repository": "git://github.com/#company-name/repository-name.git"
}
The .npmrc file reads:
#company-name:registry=https://npm.pkg.github.com
Whereas this is what I am running in my Github Action:
- uses: actions/checkout#v2
- uses: actions/setup-node#v2
with:
node-version: '12.x'
registry-url: 'https://npm.pkg.github.com'
# Defaults to the user or organization that owns the workflow file
scope: '#company-name'
# ...
- name: Install and publish
working-directory: .generated/
run: |
sudo npm install
sudo npm publish
env:
NODE_AUTH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
I am following the docs but it seems I am missing something.

Answer 1

The way we were able to get around this issue was by adding a simple script to the action:
- name: Install Dependencies
run: |
echo "#INSERT_ORG_NAME:registry=https://npm.pkg.github.com" > .npmrc
echo "//npm.pkg.github.com/:_authToken=$GITHUB_PAT" >> .npmrc
npm install
env:
GITHUB_PAT: ${{ secrets.REPO_READ_PAT }}
Second line is because we're dealing with a private repo.

Answer 2

i am using a private repository and my credentials was expired, with this situation i faced similar issue on executing
npm i
to fix this, i just edited my .npmrc to have always-auth = false and executed
npm i --registry https://registry.npmjs.org which worked for me.
