GemInstaller

It provides automated installation, loading and activation of RubyGems for Ruby apps.

Features:

• Automatically install the correct versions of all required gems wherever your app runs.
• Automatically ensure installed gems and versions are consistent across multiple applications, machines, platforms, and environments
• Automatically activate correct versions of gems on the ruby load path when the app runs ('require_gem'/'gem')
• Automatically reinstall missing dependency gems (built in to RubyGems > 1.0)
• Automatically detect correct platform to install for multi-platform gems (built in to RubyGems > 1.0)
• Print YAML for "rogue gems" which are not specified in the current config, to easily bootstrap your config file, or find gems that were manually installed without GemInstaller.
• Allow for common configs to be reused across projects or environments by supporting multiple config files, including common config file snippets, and defaults with overrides.
• Allow for dynamic selection of gems, versions, and platforms to be used based on environment vars or any other logic.
• Avoid the "works on demo, breaks on production" syndrome
• Solve world hunger, prevent the global energy crisis, and wash the socks.

What is new in this release:

• Handle platforms in gem list version output for Rubygems 1.3.7.

What is new in version 0.5.5:

• Add source to -bundler-export option. Handle Rubygems errors when parsing gem prerelease versions in older Rubygems versions.

Limitations:

• GemInstaller has been deprecated in favor of Bundler.
