Not recognizes packrat init file

[jennysjaarda]

I am trying to install a package with github via

 devtools::install_github("xiaodaigh/disk.frame")

But when packrat mode is on, I get the following errors. Specifically it says it can't find the packrat/init.R file which definitely exists...

Downloading GitHub repo xiaodaigh/disk.frame@master
   NULL
   Error in file(filename, "r", encoding = encoding) : 
     cannot open the connection
   Calls: source -> file
   In addition: Warning message:
   In file(filename, "r", encoding = encoding) :
     cannot open file 'packrat/init.R': No such file or directory
   Execution halted
Error: Failed to install 'disk.frame' from GitHub:
  System command error, exit status: 1, stdout + stderr:

This looks like a bug in callr. See also:

In the meantime until this is fixed in callr, as a workaround, you can downgrade callr
