use_lockfile

By default, rv uses a lockfile to ensure packages are sourced from the same location with the same version on each installation and across systems. While rv is designed at its core to be a project package manager, it can also be used as a package installer. In this case, use_lockfile can be set to false and no lockfile will be used during dependency resolution.

Without this configuration option, rv will completely invalidate a project library and re-sync if a lockfile is not present since it is unable to track the source with full confidence. This is because rv was designed with reproducibility at front of mind. In rv, opting out of using the lockfile is equivalent to opting out of the reproducibility guarantees and therefore does not invalidate a project library when the lockfile is absent.

Example

use_lockfile = false
[project]
name = "no lockfile"
r_version = "4.5"
repositories = [
    { alias = "PPM", url = "https://packagemanager.posit.co/cran/latest" },
]
dependencies = [
    "dplyr",
]
