SYNOPSIS

carton install [--deployment] [--cached] [--path=PATH] [--without develop]

DESCRIPTION

Install the dependencies for your application. This command has two modes and the behavior is slightly different.

DEVELOPMENT MODE

carton install

If you run "carton install" without any arguments and if cpanfile exists, carton will scan dependencies from cpanfile and install the modules.

If you run "carton install" for the first time (i.e. cpanfile.snapshot does not exist), carton will fetch all the modules specified, resolve dependencies and install all required modules from CPAN.

If cpanfile.snapshot file does exist, carton will still try to install modules specified or updated in cpanfile, but uses cpanfile.snapshot for the dependency resolution, and then cascades to CPAN.

carton will analyze all the dependencies and their version information, and it is saved into cpanfile.snapshot file. It is important to add cpanfile.snapshot file into a version controlled repository and commit the changes as you update your dependencies.

DEPLOYMENT MODE

If you specify the "--deployment" command line option or the cpanfile.snapshot exists, carton will only use the dependencies specified in the cpanfile.snapshot instead of resolving dependencies.

OPTIONS

--deployment

Force the deployment mode. See ``DEPLOYMENT MODE'' above.

--cached

Locate distribution tarballs in "vendor/cache" rather than fetching them from CPAN mirrors. This requires you to run "carton bundle" prior to the deployment and commit or sync the content of "vendor" directory to the other host you run "carton install" on.

--cpanfile

Specify the alternate path for cpanfile. By default, "carton install" will look for the file "cpanfile" in the current directory, then upwards till the root directory, in case the command runs from a sub directory.

Carton assumes the directory where your cpanfile (or altenate path) exists as a project root directory, and will look for the snapshot file as well as install directory ("local") and "vendor/cache" relative to it.

--path

Specify the path to install modules to. Defaults to local in the directory relative to where "cpanfile" is.

NOTE: this option, as of version 1.0, is not preserved across multiple runs of "carton install" or other commands such as "carton list" or "carton exec". You can choose to set the path in "PERL_CARTON_PATH" environment variable to persist it across commands.

--without

By default, "carton install" will install all the phases for dependencies, including "develop". You can specify phases or features to exclude, in the comma separated list.

  carton install --deployment --without develop

NOTE: "--without" for the initial installation (without cpanfile.snapshot) is not supported at this moment.
