Off topic:DADA2 install help

Question

[cmines98]

Hello, I am having trouble downloading DADA2 onto R studio Version 1.1.463

I have tried just about every option on this link:

https://benjjneb.github.io/dada2/dada-installation.html

when using this:

library("devtools")
devtools::install_github("benjjneb/dada2")

I get this error message:

library("devtools")
Loading required package: usethis
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
namespace ‘rlang’ 0.1.6 is already loaded, but >= 0.3.0 is required
Error: package or namespace load failed for ‘devtools’

devtools::install_github("benjjneb/dada2")
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
namespace ‘rlang’ 0.1.6 is already loaded, but >= 0.3.0 is required

what am I doing wrong and how can I fix it, thank you for any help!!!
