Current Behavior:

I am attempting to configure a project to install dependencies from NPM. I will be publishing the project to GitHub Packages as a private package. If I use this syntax in my project's .npmrc:

@my-org:registry=https://npm.pkg.github.com/

I can install dependencies from NPM using npm install on my local machine. However, I cannot publish to GitHub Packages using npm publish. NPM informs me that I'm not authenticated. If I use this syntax in my project's .npmrc:

registry=https://npm.pkg.github.com/my-org/

I can publish using npm publish, but I cannot install dependencies with npm install. NPM informs me that it's trying to install dependencies from GitHub Packages, rather than NPM.

Expected Behavior:

Based on my reading, both syntaxes should be compatible with npm install and npm publish. However, it appears I can only use one or the other, based on my intended use.

Steps To Reproduce:

1. Install Node v15.7.0 and NPM 7.4.3 via nvm.

2. Log in to GitHub Packages with the command:

   npm login --scope=@my-org --registry=https://npm.pkg.github.com

3. Check our ~/.npmrc file in our home folder. It should read:

   @my-org:registry=https://npm.pkg.github.com/
   //npm.pkg.github.com/:_authToken=<auth-token-used-for-login>
   

4. Create project with the following package.json:

   {
     "name": "@my-org/my-package",
     "description": "A test.",
     "version": "1.0.0",
     "scripts": {
       "test": "echo \"Error: no test specified\" && exit 1"
     },
     "repository": {
       "type": "git",
       "url": "https://github.com/my-org/my-package.git"
     },
     "keywords": ["example"],
     "author": "Me",
     "license": "ISC",
     "bugs": {
       "url": "https://github.com/my-org/my-package/issues"
     },
     "homepage": "https://github.com/my-org/my-package",
     "dependencies": {
       "bootstrap": "^4.5.2"
     }
   }

5. Add the following .npmrc to our project:

   @my-org:registry=https://npm.pkg.github.com/
   

6. Run npm install. Installation should succeed.

7. Run npm publish. Receive the following error:

   npm ERR! code ENEEDAUTH
   npm ERR! need auth This command requires you to be logged in.
   npm ERR! need auth You need to authorize this machine using `npm adduser`

8. Change the project .npmrc to:

   registry=https://npm.pkg.github.com/my-org/
   

9. Run npm publish. Publishing should succeed.

10. rm -rf node_modules/ package-lock.json in project.

11. Run npm install. Receive following error:

    npm ERR! code E401
