Error in gzfile(file, mode) : cannot open the connection

hi , i want make a cv by help this link but when run preview_shinyCV() i get an error. how can resolve this error.
(i use R version 3.6.1 and Rstudio Version 1.3.401)

Error in gzfile(file, mode) : cannot open the connection
In addition: Warning message:
In gzfile(file, mode) :
  cannot open compressed file 'cv_path/www/view_mode.rds', probable reason 'No such file or directory'

Does this file exists on your system ?
The error seems to tell that the file does not exist.

www folder is exists but the file view_mode.rds don't exists in this folder.

There must be something off with the initialization. I suggest you retry the step explained in the post.
The file should have been created when doing preview

Don't forget to pass a cv_path in the argument. I guess this is the directory of your cv folder ?

Otherwise, you'll need to provide us with a reproductible example to help us help you. We can't guess what is wrong on your side. Thanks !
