npm list does not show installed package

Question

I'm having trouble understanding npm. I have a node.js project with react, but I am not able to find the latter with npm list.

I certainly have it installed, because my project using react works.

I also have it in my package.json file under "dependencies":

"dependencies": {
    "react": "^16.4.1"
}

Also, if I search for react on my drive, I find the module for it in my project folder:

user/Dev/project/node_modules/react

However, if I do npm list react, I get nothing:

me ~/D/project> npm list react
[email protected] /Users/me/Dev/project
└── (empty)

Even if I do npm install or even specifically npm install react --save, no change.

Nor is the package listed with npm list or npm list -g (with or without --depth=0), except I get further indications that npm does not 'see' the react module:

UNMET PEER DEPENDENCY [email protected]

I'm using npm v5.6.0.

Any ideas?

I fixed this by running npm update command. (If that doesn't work try to delete node_modules and package-lock.json prior to running npm_update)
