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

If you haven’t already installed Node, download and install Node.js. For best results, use the latest LTS (long-term support) release of Node.js.

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 v4.0 or greater.
    • npm --version Should be 2.x or 3.x.

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

If you have multiple versions of Python installed, use this command to select which one npm uses for building compiled add-ons:

npm config set python c:/Python2.7/python

If you have multiple versions of Microsoft Visual Studio installed, use this command to select which one npm uses to build compiled add-ons:


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.

If you are behind a corporate proxy, you may need to configure npm to use it:

npm config set proxy
npm config set https-proxy
