package-lock

(Re-)Build package-lock.json or npm-shrinkwrap.json file from node_modules folder

npm@5 Creating package-lock.json

Copying node_modules folders and trying to install additional packages leads to a complete removal of all copied packages with npm@>=5.0.

A package.json file would solve this issue but nonetheless you would need to create one with all it's dependencies.

Running package-lock on the folder which contains node_modules creates the missing package-lock.json file and in case the package.json is missing, it will be created as well. With this you are now save to install additional packages with npm i ...

npm@4, npm@3 Creating npm-shrinkwrap.json

For npm@<=4.x you can also use this package to create a npm-shrinkwrap.json file for fixing you dependencies. For me running npm shrink is mostly a mess as there is always an extraneous dependency showing up (especially after a dedup).

1. Make a fresh install with

   rimraf node_modules npm-shrinkwrap.json
   npm i --production
   

2. Now create the npm-shrinkwrap.json file with

   package-lock -s
   

Installation

Requires nodejs.

$ npm install -g package-lock

Usage

Usage: package-lock [options]

  -p, --package           force appending found packages to `optionalDependencies` in package.json
  -r, --resolve <string>  replace resolved repository
  -s, --shrink            write `npm-shrinkwrap.json` instead of `package-lock.json`
  -h, --help              output usage information
