Plotly install problem

[AMillanFL]

Hi,

Trying to convert a working shiny app to electron I get an error with the use of plotly.
I found this error message :
ERROR: package or namespace load failed for 'plotly' in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
The package 'vctrs' 0.2.2 is already loaded but >= 0.3.0 is required

I have installed in \resources\app\R-Portable-Win\library\ the packages plotly 4.9.2.1 and vctrs 0.3.4.

Thanks for your help.
