38 ### Synopsis
39
40 ```bash
41 npm rebuild [<package-spec>] ...]
42
43 alias: rb
44 ```
45
46 ### Description
47
48 This command does the following:
49
50 1. Execute lifecycle scripts (`preinstall`, `install`, `postinstall`, `prepare`)
51 2. Links bins depending on whether bin links are enabled
52
53 This command is particularly useful in scenarios including but not limited to:
54
55 1. Installing a new version of **node.js**, where you need to recompile all your C++ add-ons with the updated binary.
56 2. Installing with `--ignore-scripts` and `--no-bin-links`, to explicitly choose which packages to build and/or link bins.
57
58 If one or more package specs are provided, then only packages with a name and version matching one of the specifiers will be rebuilt.
59
60 Usually, you should not need to run `npm 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`).
61
62 If there is a `binding.gyp` file in the root of your package, then npm will use a default install hook:
63
64 ```
65 "scripts": {
66 "install": "node-gyp rebuild"
67 }
68 ```
69
70 This default behavior is suppressed if the `package.json` has its own `install` or `preinstall` scripts. It is also suppressed if the package specifies `"gypfile": false`
71
72 ### Configuration
73
74 #### `global`
75
76 - Default: false
77 - Type: Boolean
78
79 Operates in "global" mode, so that packages are installed into the `prefix` folder instead of the current working directory. See [folders](/cli/v11/configuring-npm/folders) for more on the differences in behavior.
80
81 - packages are installed into the `{prefix}/lib/node_modules` folder, instead of the current working directory.
82 - bin files are linked to `{prefix}/bin`
83 - man pages are linked to `{prefix}/share/man`
84
85 #### `bin-links`
86
87 - Default: true
88 - Type: Boolean
89
90 Tells npm to create symlinks (or `.cmd` shims on Windows) for package executables.
91
92 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.
93
94 #### `foreground-scripts`
95
96 - Default: `false` unless when using `npm pack` or `npm publish` where it defaults to `true`
97 - Type: Boolean
98
99 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.
100
101 Note that this will generally make installs run slower, and be much noisier, but can be useful for debugging.
102
103 #### `ignore-scripts`
104
105 - Default: false
106 - Type: Boolean
107
108 If true, npm does not run scripts specified in package.json files.
109
110 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.
111
112 #### `workspace`
113
114 - Default:
115 - Type: String (can be set multiple times)
116
117 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.
118
119 Valid values for the `workspace` config are either:
120
121 - Workspace names
122 - Path to a workspace directory
123 - Path to a parent workspace directory (will result in selecting all workspaces within that folder)
124
125 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.
126
127 This value is not exported to the environment for child processes.
128
129 #### `workspaces`
130
131 - Default: null
132 - Type: null or Boolean
133
134 Set to true to run the command in the context of **all** configured workspaces.
135
136 Explicitly setting this to false will cause commands like `install` to ignore workspaces altogether. When not set explicitly:
137
138 - 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.
139
140 This value is not exported to the environment for child processes.
141
142 #### `include-workspace-root`
143
144 - Default: false
145 - Type: Boolean
146
147 Include the workspace root when workspaces are enabled for a command.
148
149 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.
150
151 This value is not exported to the environment for child processes.
152
153 #### `install-links`
154
155 - Default: false
156 - Type: Boolean
157
158 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.
