Unable to snapshot: Error in findLocalRepoForPkg

[Eric Kernfeld]

Can you comment on this issue? I keep getting the same error when I try to snapshot the current state of my library.

Error in findLocalRepoForPkg(pkg, repos, fatal = fatal) : 
  No package 'XXX' found in local repositories specified

Package XXX is not something that I purposefully installed or that I use in my code. When I try to clean it with packrat::clean(), I get 

Error in find.package(pkgs, lib) : 

  there is no package called ‘XXX’

I think XXX is not installed, but it may be a dependency of some package YYY that is installed. I don't know why this wasn't taken care of when YYY was installed, but I am going to try installing XXX. If that fails, is there a way for me to identify YYY and remove it? 

Also, running packrat::snapshot() takes literally hours. It makes problems like this very difficult to solve. All I want is to take the current state of my library -- which is already sitting right there on the file system, and I know because  the library() statements in my code are working as expected -- and record that in packrat.lock. So is there a way to skip whatever else  packrat::snapshot() is doing?

Thank you!

Update: simply installing package XXX seems to work, and by "literally hours", I guess I meant about 20 minutes. I should drink less coffee, sorry.

Hi Eric, the snapshot process can definitely feel like forever, with or without coffee! The new renv package supersedes packrat for most uses and is dramatically faster and less fragile, you might want to check that out, especially the next time you run into a packrat problem.

I do use renv where possible, but this project uses several local repos, which are easier for me to track with Packrat.

Oh OK, fair enough!
