bundle-lock(1) -- Creates / Updates a lockfile without installing
=================================================================

## SYNOPSIS

`bundle lock` [--update]
              [--local]
              [--print]
              [--lockfile=PATH]

## DESCRIPTION

Lock the gems specified in Gemfile.

## OPTIONS

* `--update=<*gems>`:
  Ignores the existing lockfile. Resolve then updates lockfile. Taking a list
  of gems or updating all gems if no list is given.

* `--local`:
  Do not attempt to connect to `rubygems.org`. Instead, Bundler will use the
  gems already present in Rubygems' cache or in `vendor/cache`. Note that if a
  appropriate platform-specific gem exists on `rubygems.org` it will not be
  found.

* `--print`:
  Prints the lockfile to STDOUT instead of writing to the file system.

* `--lockfile=<path>`:
  The path where the lockfile should be written to.

## UPDATING ALL GEMS

If you run `bundle lock` with `--update` option without list of gems, bundler will
ignore any previously installed gems and resolve all dependencies again based
on the latest versions of all gems available in the sources.

## UPDATING A LIST OF GEMS

Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of
the gems that you specified locked to the versions in the `Gemfile.lock`.

For instance, you only want to update `nokogiri`, run `bundle lock --update nokogiri`.

Bundler will update `nokogiri` and any of its dependencies, but leave the rest of the
gems that you specified locked to the versions in the `Gemfile.lock`.
