dplyr::select() no longer works

[joeystan]

I have been using R and tidyverse for several years on my office computer. Suddenly, tidyr::select() is no longer working:

 library(dplyr)

Attaching package: ‘dplyr’

The following objects are masked from ‘package:stats’:

    filter, lag

The following objects are masked from ‘package:base’:

    intersect, setdiff, setequal, union

Warning message:
package ‘dplyr’ was built under R version 3.6.2 
> mtcars %>% select(mpg)
Error: 'vec_as_subscript' is not an exported object from 'namespace:vctrs'
Run `rlang::last_error()` to see where the error occurred.

Does anyone have any suggestions for how to fix this?

vec_as_subscript() is a new function that was introduced in vctrs 0.2.2. It seems that you have 0.2.0 installed.

Could you try updating vctrs to the latest version?

Beautiful. Updated vctrs and it works perfectly. I should have known how to intepret that message better. Thank you!
