Installing Node and StrongLoop on Windows presents some special challenges and requirements.
The Node package manager tool, npm, uses Git to download packages from Github.
To install Git:
- Go to http://git-scm.com/download,
- Download the version for Windows. Currently this is version 1.9.4.
- 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:
- Go to http://nodejs.org/download/
- Download the latest "Windows Installer (.msi)", 32 or 64-bit, as appropriate
- Run the installer.
The version of npm installed as part of the Node installation has known issues on Windows. To avoid these problems, reinstall npm, which actually installs npm2:
Follow these steps:
- After installing the prerequisites as instructed above, restart your machine to ensure all configuration changes have taken effect.
- Open a Windows Command Prompt.
Try the following:
Restart Windows, to ensure configuration has taken effect.
Verify dependencies are installed:

node --versionShould be v0.10.x or v0.12.x.
npm --versionShould be 1.x or 2.x.

Tips and tricks
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
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
--msvs_version=2013(as appropriate) to the end of npm install commands, for example:
npm install -g strongloop --msvs_version=2012
