ReinstallWithOptions

Use this when you need to attach flags such as --prefer-source or --prefer-dist:

func (c *Composer) ReinstallWithOptions(packageName string, options map[string]string) error

options := map[string]string{"prefer-source": ""}
err := comp.ReinstallWithOptions("symfony/console", options)

Batch reinstall

To reinstall multiple packages at once, use ReinstallMultiple(packages []string), equivalent to composer reinstall pkg1 pkg2 ....

Version requirement

reinstall is a native command introduced in Composer 2.2+. For older Composer versions, use the Remove + RequirePackage combination to achieve reinstallation.
