# Updating Dependencies

If you want to change our constraints (change which packages and versions we accept in the chef), there are several places to do so:

* [Gemfile](../../../Gemfile) and [Gemfile.lock](../../../Gemfile.lock):  All gem version constraints (update with `bundle update`)
* [omnibus_overrides.rb](../../../omnibus_overrides.rb):  Pinned versions of omnibus packages.
* [omnibus/Gemfile](../../../omnibus/Gemfile) and [omnibus/Gemfile.lock](../../../omnibus/Gemfile.lock): Gems for the omnibus build system itself.

In order to update everything, run `rake dependencies`.  Note that the [Gemfile.lock](Gemfile.lock) pins Windows platform gems, and to fully regenerate the lockfile, you must use the following commands, or run `rake dependencies:update_gemfile_lock`:

```bash
bundle lock --update --add-platform ruby x64-mingw32 x86-mingw32
```
