Roxygen Warning “cannot open the connection” “Permission Denied”

问题

I'm working with roxygen2 and for some reason I can't get it to run.
I've tried:

> devtools::load_all()
> devtools::document()

which resulted in:

Updating xxxx documentation 
Loading xxxx
First time using roxygen2. Upgrading automatically... 
Writing NAMESPACE 
Error in file(con, "r") : cannot open the connection 
In addition: Warning message: In file(con, "r") :   cannot open file 
'C:\Users\xxxxxxx': Permission denied

I also tried:

> roxygen2::roxygenise()

yielding:

Loading xxxx
Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
  cannot open file 'C:\Users\xxxxxxxx': Permission denied

I've tried installing the 6.1.0 and 6.0.1 versions of roxygen, with same results. Any solutions? Thanks.

This appears to be a minor bug in latest roxygen2 6.1.0. See https://github.com/klutometis/roxygen/issues/766 with short term solution being offered by gustavdelius via devtools::install_github("gustavdelius/roxygen").

I imagine this will be resolved in next release of roxygen2.

Just to follow-up on this, even after using the solution above and updating to the most updated version of roxygen2 (7.0.1) I kept getting the same error. After some debugging, I found that in one of my functions I had an empty #' line in the documentation of the function. Once I omitted the empty line, I was able to run roxygenize my functions and create the documentation. Hope this helps!
