Windows-Build-Tools

On Windows? Want to compile native Node modules? Install the build tools with this one-liner. Start PowerShell as Administrator and run:

npm install --global windows-build-tools

Or, if you are using Yarn:

yarn global add windows-build-tools

After installation, npm will automatically execute this module, which downloads and installs Visual
C++ Build Tools, provided free of charge for most users by Microsoft (as part of Visual Studio Community, please consult the license to determine whether or not you're eligible). These tools are required to compile popular native modules.
If not already installed, it will also install Python 3.8, configuring your machine and npm appropriately.

:bulb: [Windows Vista / 7 only] requires .NET Framework 4.5.1 (Currently not installed automatically by this package)

Both installations are conflict-free, meaning that they do not mess with existing installations of
Visual Studio, C++ Build Tools, or Python. If you see anything that indicates otherwise, please
file a bug.

Visual Studio 2017 vs Visual Studio 2015

This module is capable of installing either the build tools from Visual Studio 2017 or Visual
Studio 2015.

By default, this tool will install the 2017 build tools. To change that, run this script with
the --vs2015 parameter.

Usage

npm [--python-mirror=''] [--proxy=''] [--debug] [--strict-ssl] [--resume] [--sockets=5] [--vcc-build-tools-parameters=''] [--vs2015] [--dry-run-only] install --global windows-build-tools

Optional arguments:

• --offline-installers: Path to a folder with already downloaded installers. See
• --python-mirror: Use a given mirror to download Python (like --python_mirror=https://npm.taobao.org/mirrors/python/). You can alternatively set a PYTHON_MIRROR environment variable.
• --proxy: Use a given proxy. You can alternatively set a PROXY environment variable.
• --debug: Be extra verbose in the logger output. Equal to setting the environment variable DEBUG to *.
• --strict-ssl: Enables "Strict SSL" mode. Defaults to false.
• --resume: By default, windows-build-tools will resume aborted downloads. Set to false to disable.
• --sockets: Specifies the number of http sockets to use at once (this controls concurrency). Defaults to infinity.
• --vcc-build-tools-parameters: Specifies additional parameters for the Visual C++ Build Tools 2015. See below for more detailed usage instructions.
• --silent: The script will not output any information.
• --vs2015: Install the Visual Studio 2015 Build Tools instead of the Visual Studio 2017 ones.
• --dry-run-only: Don't actually do anything, just print what the script would have done.
• --include-arm64-tools: Include the optional Visual Studio components required to build binaries for ARM64 Windows. Only available with the 2017 and newer build tools and Node.js v12 and up.

Supplying Parameters to the VCC Build Tools

You can pass additional parameters directly to the VCC Build Tools installer. This tool does not
check if the parameters make sense - passing incorrect parameters might break the whole
installation.

Supply parameters to windows-build-tools as a JSON array. Here's quick example (note the double quotes):

npm --vcc-build-tools-parameters='[""--allWorkloads""]' install --global windows-build-tools

Visual Studio 2015 Parameters

If you run windows-build-tools with --vs2015, these parameters are available:

• /AdminFile: Specifies the installation control file.
• /CreateAdminFile: Specifies the location to create a control file that can then be used
• /CustomInstallPath: Set Custom install location.
• /ForceRestart: Always restart the system after installation.
• /Full: Install all product features.
• /InstallSelectableItems: <item1;item2;...;itemN> Choose which selectable item(s) to be installed.
  -selectable item to be installed, just pass in this switch without any value.
• /Layout: Create a copy of the media in specified folder.
• /NoRefresh: Prevent setup checking for updates from the internet.
• /NoRestart: Do not restart during or after installation.
• /NoWeb: Prevent setup downloading from the internet.
• /Passive: Display progress but do not wait for user input.
• /ProductKey: <25-character product key> Set custom product key (no dashes).
• /PromptRestart: Prompt the user before restarting the system.
• /Repair: Repair the product.
• /Uninstall: Uninstall the product.
• /Uninstall /Force: Uninstall the product and features shared with other products.

Visual Studio 2017 Parameters

The available parameters are documented here.

Offline Installation

By default, windows-build-tools will download the latest installers from Microsoft each time
it's installed. Alternatively, you can prepare a folder that contains installers. They need to
have their original names:

• Visual Studio Build Tools: vs_BuildTools.exe or BuildTools_Full.exe
• Python: python-3.8.1.amd64.msi or python-3.8.1.msi

Then, run windows-build-tools with the --offline-installers argument:

npm install -g windows-build-tools --offline-installers="C:\Users\John\installers"

Support & Help

This package currently only handles the most common use case, none of the edge cases. If you encounter errors, we'd greatly appreciate error reports (and even pull requests). This is currently tested on Windows 10.

Node versions

• windows-build-tools 4.0 and up require at least Node v8.
• windows-build-tools 3.0 and up require at least Node v6.
• windows-build-tools 1.0 and up require at least Node v4.

Where is Python installed?

It's saved under %USERPROFILE%\.windows-build-tools\python38.

Installing as a Non-Administrator

windows-build-tools works best if installed from an account with administrative rights. However,
thanks to @brucejo75, the following steps can be taken to install to a different user account:

1. From your non-admin account (e.g. <Me>) run cmd.exe as administrator.
2. Set the following environment variables in the new command shell:

set APPDATA=C:\Users\<Me>\AppData\Roaming
npm config set prefix C:\Users\<Me>\AppData\Roaming\npm
set USERNAME=<Me>
set USERPROFILE=C:\Users\<Me>

Ensure that the variables passed match your location of npm's roaming data and the location
of user profiles on your machine. For <me>, substitute the name of the account you want to
install windows-build-tools for. For more information, see the npm config set prefix
description here.

3. Run npm install -g windows-build-tools

Examples of Modules Supported

In theory, windows-build-tools supports all pure C++ addons for Node.js (and virtually everything
else that requires a native compiler toolchain to be installed on your machine).

To ensure that that's true, we take a fresh Windows 10 installation, add windows-build-tools, and
ensure that the most popular native Node addons compile from source. Those are: node-sass, bcrypt, sqlite3, serialport, websocket, deasync, grpc, canvas, sharp,
hiredis, leveldown, nodegit, zqm, ffi, libxmljs, iconv, ref, sleep, microtime, couchbase, bignum,
kerberos, and ursa.
