Private github repo as dependency is extraneous on npm install - node.js

Question

This is my first time using a private repo as a dependency in another project. I think I am doing it right, but the dependency is not available in the new project after install and is not in node_modules.
Following this post I can see that I am including it in the package.json correctly like:
"myPackage": "git+https://github.com/myusername/mygitrepository.git"
When I run npm install on this package, I see this that it does not have an error, but after this dependency in the list, it is shown with extraneous(git+https://github.com/myusername/mygitrepository.git).
Even though there is the extraneous issue, there is no error, and the dependency is not available or listed in node_modules.
Update: repo_A package.json
{
"name": "project-name",
"version": "1.0.0",
"description": "Backend utility functions",
"scripts": {
"test": "mocha"
},
"repository": {
"type": "git",
"url": "git+https://github.com/user/repo.git"
},
"author": "me",
"license": "ISC",
"bugs": {
"url": "https://github.com/user/repo/issues"
},
"homepage": "https://github.com/user/repo#readme",
"dependencies": {
"lodash": "^4.17.4",
"mongodb": "^2.2.25",
"redis": "^2.7.1",
"winston": "^2.3.1"
}
}
Update: repo_B package.json
{
"name": "main-project-name",
"version": "1.0.0",
"description": "",
"repository": {
"type": "git",
"url": "git+https://github.com/user/repo.git"
},
"author": "someone else",
"homepage": "https://github.com/user/repo.git",
"dependencies": {
"async": "2.1.4",
"chai": "^3.5.0",
"langs": "1.1.0",
"lodash": "4.13.1",
"node-stopwatch": "0.0.1",
"request": "2.74.0",
"winston-loggly": "^1.3.1",
"utils": "user/repo_A.git#master"
},
"scripts": {
"test": "mocha"
}
}
Update for latest steps
Here are the steps I am following now to test each possible solution, followed by the output:
rm -rf node_modules
npm cache clean
npm install

If you specify https then that will be looking for a login user and password I believe, which I don't think it can load automatically. I would list it simply as "user/repo" and make sure that machine has an ssh key on it that is in github like the setup described in help such as https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/#platform-linux and that things are setup so that pulling down that repo does not require user interaction.
EDIT: After testing, I think the issue is that your name in the package.json does not match how you have listed it in your main project's dependencies. In my test, this resulted in the modules being installed but I got the extraneous message.
