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 --production 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 by Microsoft. These tools are required to compile popular native modules.
If not already installed, it will also install Python 2.7, 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. Since Node's underlying build tools still don't fully support 2017, you might
have a better experience with 2015 - even if it sounds a bit outdated. On the other hand, if
you are only trying to compile a certain set of modules, the 2017 build tools are smaller and
install a bit quicker.
By default, this tool will install the 2015 build tools. To change that, run this script with
the --vs2017
parameter.
Usage
npm [--python-mirror=''] [--proxy=''] [--debug] [--strict-ssl] [--resume] [--sockets=5] [--vcc-build-tools-parameters=''] [--vs2017] [--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.--vs2017
: Install the Visual Studio 2017 Build Tools instead of the Visual Studio 2015 ones.--dry-run-only
: Don't actually do anything, just print what the script would have done.
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
/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
If you run windows-build-tools
with --vs2017
, 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-2.7.14.amd64.msi
or python-2.7.14.msi
Then, run windows-build-tools
with the --offline-installers
argument:
npm install -g --production 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\python27
.
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:
- From your non-admin account (e.g. <Me>) run
cmd.exe
as administrator. - 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.
- Run
npm install -g --production 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.
