Failed to install 'nCov2019' from GitHub

[bluesun2019]

Hi,
I am a newer to GitHub...and I have no idea with why I can't install this package. This is the error I have come across:
Error: Failed to install 'nCov2019' from GitHub: Incorrect number of arguments (3), expecting 2 for 'processx_kill'
Here is the complete version of my try:

remotes::install_github("GuangchuangYu/nCov2019",dependencies = TRUE)
Downloading GitHub repo GuangchuangYu/nCov2019@master
These packages have more recent versions available.
It is recommended to update all of them.
Which would you like to update?

1: All                              
2: CRAN packages only               
3: None                             
4: shiny   (1.4.0 -> 1.4.0.2) [CRAN]
5: tinytex (0.19  -> 0.20   ) [CRAN]
6: stringi (1.4.5 -> 1.4.6  ) [CRAN]
