There are several options you can use to control how a package is installed.
Saving dependencies
By default, any package you install will be saved as a dependency. To save it as a development dependency instead, use the --saveDev flag.
installtestbox--saveDev
If you DON'T want the package you're installing to be saved as a dependency pass save=false or negate the save flag as --!save.
installcborm--!save
Production Installation
When you install a package, all dependencies will be installed. If you want to skip development dependencies, use the --production flag. This will also cause CommandBox to obey the package's ignore property in its box.json.
installcbvalidation--production
Verbose Installation
If you're a glutton for information, or perhaps you just want to debug what's going on, set the --verbose flag to get extra debugging information out of the install command including a list of every file that's installed.
installcbi18n--verbose
Forced Installation
If CommandBox sees the directory that it was going to install into already exists with a newer or equal version of the package inside, it will decline to install again since it would be overwriting what's already there. If you want to install anyway, use the --force flag.
