MavensMate was a popular community plugin for the Force.com platform, built on the Sublime Text IDE (created and maintained by Joe Ferraro) as a free alternative to the official Force.com IDE.

Under certain conditions on Windows 7/8 (often proxy/firewall configurations), installation could fail with an error similar to:

Installation of Sublime Text plugin failed. This is likely due to the installer being unable to reach GitHub. If you are behind a firewall or using a proxy, you should configure git accordingly (google: git config --global https.proxy) and ensure your HTTPS/HTTPS_PROXY environment variable(s) are set properly. Otherwise, please log an issue on the MavensMate GitHub project.

There is an existing GitHub issue with a workaround suggested by Joe Ferraro. The steps that worked for me were:

  1. Open Command Prompt and move to the Sublime Text Packages directory (adjust username if needed):
cd "C:\Users\username\AppData\Roaming\Sublime Text 3\Packages"
  1. Clone the plugin and initialize submodules manually:
git clone --recursive http://github.com/joeferraro/MavensMate-SublimeText.git MavensMate
cd MavensMate
git submodule init
git submodule update

After restarting Sublime Text, the plugin should be available. Remember to configure your workspace via MavensMate → Settings.
