$ npm install npminstall -gIt is integrated in cnpm.
$ npm install cnpm -g
# will use npminstall
$ cnpm installUsage:
npminstall
npminstall <pkg>
npminstall <pkg>@<tag>
npminstall <pkg>@<version>
npminstall <pkg>@<version range>
npminstall <alias>@npm:<name>
npminstall <folder>

npminstall <github username>/<github project>
Can specify one or more: npm install ./foo.tgz bar@stable /some/folder
If no argument is supplied, installs dependencies from ./package.json.
Options:
--production: won't install devDependencies
--save, --save-dev, --save-optional: save installed dependencies into package.json
-g, --global: install devDependencies to global directory which specified in `$ npm config get prefix`
-r, --registry: specify custom registry
-c, --china: specify in china, will automatically using chinese npm registry and other binary's mirrors
-d, --detail: show detail log of installation
--trace: show memory and cpu usages traces of installation
--ignore-scripts: ignore all preinstall / install and postinstall scripts during the installation
--no-optional: ignore optionalDependencies during the installation
--forbidden-licenses: forbit install packages which used these licenses
--engine-strict: refuse to install (or even consider installing) any package that claims to not be compatible with the current Node.js version.
--flatten: flatten dependencies by matching ancestors dependencies
--registry-only: make sure that all packages are installed from registry. Any package that is installed from remote(e.g.: git, remote url) will lead to a failure of installation.
--cache-strict: use disk cache even on production envUsage:
npmuninstall <pkg>
npmuninstall <pkg>@<version>
npmuninstall <pkg>@<version> [<pkg>@<version>]
npminstall <alias>@npm:<name>Usage:
npmlink <folder>$ npm install npminstall --saveconst npminstall = require('npminstall');

This project is inspired by pnpm, and has a similar store structure like pnpm. You can read pnpm vs npm to see the different with npm.
- You can't install from shrinkwrap(and don't want to support for now).
- Peer dependencies are a little trickier to deal with(see rule 1 below).
- You can't publish npm modules with bundleDependencies managed by npminstall(because of rule 2 below).
npminstallwill collect all postinstall scripts, and execute them until all dependencies installed.- If last install failed, better to cleanup node_modules directory before retry.
Two rules:
- The latest version of modules will link at
options.storeDir'snode_modules. - Module's dependencies will link at module's
node_modules.
e.g.:
- app:
{ "dependencies": { "debug": "2.2.0" } }(root) - [email protected]:
{ "dependencies": { "ms": "0.7.1" } }
app/
├── package.json
└── node_modules
├── [email protected]@debug
│ ├── node_modules
│ │ └── ms -> ../../[email protected]@ms
├── _ms0.7.1@ms
├── debug -> [email protected]@debug
└── ms -> [email protected]@ms # for peerDependenciesnpminstall will always try to install the maximal matched version of semver:

mod/
koa@~1.1.0
# will install two different version of koa when use npminstall.
you can enable flatten mode by --flatten flag, in this mod, npminstall will try to use ancestors' dependencies to minimize the dependence-tree.

npminstall will always treat n.x and n.m.x as flattened

support selective version resolutions like yarn. which lets you define custom package versions inside your dependencies through the resolutions field in your package.json file.
resolutions also supports npm alias. It's a workaround feature to fix some archived/inactive/ package by uploading your own bug-fixed version to npm registry.
see use case at unittest package.json.
