Cannot load doBy package

With doBy package successfully installed, library(doBy) cannot load doBy
the error message is as follows.

Error: package or namespace load failed for ‘doBy’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
네임스페이스 ‘vctrs’ 0.2.4는 이미 로드되었으나 >= 0.3.0가 필요합니다
(Transalation: Namespace 'vctrs' 0.2.4 is already loaded but >= 0.3.0 is required)
