## NAME
       **bundle-lock** - Creates / Updates a lockfile without installing

## SYNOPSIS
       **bundle**  **lock** [--update] [--local] [--print] [--lockfile=PATH] [--full-index] [--add-platform]
       [--remove-platform] [--patch] [--minor] [--major] [--strict] [--conservative]

## 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  plat‐
              form-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.

### --full-index
              Fall back to using the single-file index of all gems.

### --add-platform
              Add a new platform to the lockfile, re-resolving for the addition of that platform.

### --remove-platform
              Remove a platform from the lockfile.

### --patch
              If updating, prefer updating only to next patch version.

### --minor
              If updating, prefer updating only to next minor version.

### --major
              If updating, prefer updating to next major version (default).

### --strict
              If  updating, do not allow any gem to be updated past latest --patch | --minor | --ma‐
              jor.

### --conservative
              If updating, use bundle install conservative update behavior and do not  allow  shared
              dependencies to be updated.

## 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)](https://www.chedong.com/phpMan.php/man/Gemfile/5/markdown), 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**.

## SUPPORTING OTHER PLATFORMS
       If  you  want your bundle to support platforms other than the one you´re running locally, you
       can run **bundle** **lock** **--add-platform** **PLATFORM** to add PLATFORM to the lockfile, force bundler to
       re-resolve and consider the new platform when picking gems, all without needing to have a ma‐
       chine that matches PLATFORM handy to install those platform-specific gems on.

       For a full explanation of gem platforms, see **gem** **help** **platform**.

## PATCH LEVEL OPTIONS
       See bundle [update(1)](https://www.chedong.com/phpMan.php/man/update/1/markdown) _bundle-update.1.html_ for details.
