### Synopsis
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm rebuild [<package-spec>] ...]
|
||
|
|
|
||
|
|
alias: rb
|
||
|
|
```
|
||
|
|
|
||
|
|
### Description
|
||
|
|
|
||
|
|
This command runs the `npm build` command on the matched folders. This is
|
||
|
|
useful when you install a new version of node, and must recompile all your
|
||
|
|
C++ addons with the new binary. It is also useful when 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.
|
||
|
|
|
||
|
|
### Configuration
|
||
|
|
|
||
|
|
#### `global`
|
||
|
|
|
||
|
|
* Default: false
|
||
|
|
* Type: Boolean
|
||
|
|
|
||
|
|
Operates in "global" mode, so that packages are installed into the `prefix`
|
||
|
|
folder instead of the current working directory. See
|
||
|
|
[folders](/configuring-npm/folders) 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
|
||
|
|
* Type: Boolean
|
||
|
|
|
||
|
|
Run all build scripts (ie, `preinstall`, `install`, and `postinstall`)
|
||
|
|
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 as
|
||
|
|
`npm start`, `npm stop`, `npm restart`, `npm test`, and `npm run-script`
|
||
|
|
will still run their intended script if `ignore-scripts` is set, but they
|
||
|
|
will *not* 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 the `workspace` 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 the `npm 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 of **all** configured
|
||
|
|
workspaces.
|
||
|
|
|
||
|
|
Explicitly setting this to false will cause commands like `install` to
|
||
|
|
ignore workspaces altogether. When not set explicitly:
|
||
|
|
|
||
|
|
- Commands that operate on the `node_modules` tree (install, update, etc.)
|
||
|
|
will link workspaces into the `node_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 the `workspace` 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 the `workspace` config, or
|
||
|
|
all workspaces via the `workspaces` 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.
