Error to Use with Description of `sf`

[ismailsunni]

Hello, I am trying to see how to package works with an existing package (sf).
I tried this:

sysreqs("/home/ismailsunni/R/x86_64-pc-linux-gnu-library/3.6/sf/DESCRIPTION")

But I got this error message:

Error: JSON: EXPECTED value GOT U

Any idea why? Or perhaps I did something wrong?

Another question, is it possible to use it without installing the package? For example, I want to get a list of system dependency.

Thanks :)

Btw, I tried to check which location that made it fail, it seems in this function: https://github.com/r-hub/sysreqs/blob/master/R/sysreqs.R#L60

This issue is duplicated with #10. I will close this one.
