Synopsis

npm rebuild[<package-spec>]...]
alias: rb

Description

This command does the following:

Execute lifecycle scripts (preinstall,install,postinstall,prepare)
Links bins depending on whether bin links are enabled

This command is particularly useful in scenarios including but not limited to:

Installing a new version ofnode.js, where you need to recompile all your C++ add-ons with the updated binary.
Installing with--ignore-scripts and--no-bin-links, to explicitly choose which packages to build and/or link bins.

If one or more package specs are provided, then only packages with a name and version matching one of the specifiers will be rebuilt.

Usually, you should not need to runnpm rebuild as it is already done for you as part of npm install (unless you suppressed these steps with--ignore-scripts or--no-bin-links).

If there is abinding.gyp file in the root of your package, then npm will use a default install hook:

"scripts":{
"install":"node-gyp rebuild"
}

This default behavior is suppressed if thepackage.json has its owninstall orpreinstall scripts. It is also suppressed if the package specifies"gypfile": false

Configuration

`global`

Default: false
Type: Boolean

Operates in "global" mode, so that packages are installed into theprefix folder instead of the current working directory. Seefolders for more on the differences in behavior.

packages are installed into the{prefix}/lib/node_modules folder, instead of the current working directory.
bin files are linked to{prefix}/bin
man pages are linked to{prefix}/share/man

`bin-links`

Default: true
Type: Boolean

Tells npm to create symlinks (or.cmd shims on Windows) for package executables.

Set to false to have it not do this. This can be used to work around the fact that some file systems don't support symlinks, even on ostensibly Unix systems.

`foreground-scripts`

Default:false unless when usingnpm pack ornpm publish where it defaults totrue
Type: Boolean

Run all build scripts (ie,preinstall,install, andpostinstall) scripts for installed packages in the foreground process, sharing standard input, output, and error with the main npm process.

Note that this will generally make installs run slower, and be much noisier, but can be useful for debugging.

`ignore-scripts`

Default: false
Type: Boolean

If true, npm does not run scripts specified in package.json files.

Note that commands explicitly intended to run a particular script, such asnpm start,npm stop,npm restart,npm test, andnpm run will still run their intended script ifignore-scripts is set, but they willnot run any pre- or post-scripts.

`workspace`

Default:
Type: String (can be set multiple times)

Enable running a command in the context of the configured workspaces of the current project while filtering by running only the workspaces defined by this configuration option.

Valid values for theworkspace config are either:

Workspace names
Path to a workspace directory
Path to a parent workspace directory (will result in selecting all workspaces within that folder)

When set for thenpm init command, this may be set to the folder of a workspace which does not yet exist, to create the folder and set it up as a brand new workspace within the project.

This value is not exported to the environment for child processes.

`workspaces`

Default: null
Type: null or Boolean

Set to true to run the command in the context ofall configured workspaces.

Explicitly setting this to false will cause commands likeinstall to ignore workspaces altogether. When not set explicitly:

Commands that operate on thenode_modules tree (install, update, etc.) will link workspaces into thenode_modules folder. - Commands that do other things (test, exec, publish, etc.) will operate on the root project,unless one or more workspaces are specified in theworkspace config.

This value is not exported to the environment for child processes.

`include-workspace-root`

Default: false
Type: Boolean

Include the workspace root when workspaces are enabled for a command.

When false, specifying individual workspaces via theworkspace config, or all workspaces via theworkspaces flag, will cause npm to operate only on the specified workspaces, and not on the root project.

This value is not exported to the environment for child processes.

`install-links`

Default: false
Type: Boolean

When set file: protocol dependencies will be packed and installed as regular dependencies instead of creating a symlink. This option has no effect on workspaces.
