Error: 'data_frame' is not an exported object from 'namespace:vctrs'

I'm trying to knit the Rmd file, but the following message shows:

Error: 'data_frame' is not an exported object from 'namespace:vctrs'

So I couldn't knit.

I believe the functions that caused this are the group_by() and summarise() functions.

My dplyr version is 0.8.5
vctrs version is 0.2.4
R version is 3.5.3

Any suggestions? Thank you!

I think my R version is old. I'll update R and packages and see how it goes.

Will report back.

Hi Joavinh,
I am having same problem while running some packages (tidyverse, ggplot2) and to read my data. I updated my R version to 4.0.5 but I still receive same error. Please let me know when you find a solution.

The error:
"Error: object ‘data_frame’ is not exported by 'namespace:vctrs'
