Installing Node and StrongLoop on Windows presents some special challenges and requirements. 


Install compiler tools

If you want features such as application profiling or monitoring, you must install compiler tools and Python before you start.  See Installing compiler tools for more information.

Install Git

The Node package manager tool, npm, uses Git to download packages from Github. 

To install Git:

  1. Go to,
  2. Download the version for Windows.  Currently this is version 1.9.4.
  3. Run installer:
    • Accept default install location
    • Accept or modify Components
    • Accept start menu folder
    • Modify “Adjusting your PATH environment” to “Use Git from Windows Command Prompt”
    • Accept default “Configuring the line ending conversions”


By default, Git on Windows does not support paths longer than 260 characters; to avoid errors you must enable long paths with the following command:

C:\> git config --system core.longpaths true

Install Node.js

  1. Go to
  2. Download the latest “Windows Installer (.msi)”, 32 or 64-bit, as appropriate.
  3. Run the installer.

Install latest version of npm

The version of npm installed as part of the Node installation has known issues on Windows. To avoid these problems, install the latest version of npm:

C:\> npm install -g npm

Install StrongLoop

Follow these steps:

  1. After installing the prerequisites as instructed above, restart your machine to ensure all configuration changes have taken effect.
  2. Open a Windows Command Prompt. 
  3. Install StrongLoop:

    C:\> npm install -g strongloop


Try the following:

  1. Restart Windows, to ensure configuration has taken effect.

  2. Verify dependencies are installed:

    • python --version Should be 2.7.x
    • node --version Should be v0.10.x or v0.12.x.
    • npm --version Should be 1.x or 2.x.

FIXME any way to determine what vs– is installed? FIXME is there any way to determine what python and msbuild node-gyp has found?</div>

If you continue to have problems installing StrongLoop:

In general, provide as much information as possible.  If npm install failed, attach the npm-debug.log file.

Confirm basic npm actions

Ensure you can install a simple npm package.  Enter this command in a Windows Command Prompt shell:

C:\> npm install -g semver

You should not see any error messages.  Then enter:

C:\> semver --help

You should see a usage message displayed in the Command Prompt window.

Ensure you can install a simple Node compiled addon.  Enter this command in a Windows Command Prompt shell:

C:\> npm install -g buffertools

This command should compile and install without errors.

Tips and tricks

  1. If you have multiple versions of python installed, you can select which on is used by npm for building compiled addons:

    • npm config set python c:/Python2.7/python
  2. If you have multiple versions of Microsoft Visual Studio installed, you can select which one npm uses to build compiled add-ons like this:

    • set GYP_MSVS_VERSION=2012, or
    • Append npm --msvs_version=2012 or --msvs_version=2013 (as appropriate) to the end of npm install commands, for example: npm install -g strongloop --msvs_version=2012
