In (gnu packages cran) I added a snippet but forgot to quote it properly. The snippet looked like this: (snippet (delete-file "inst/htmlwidgets/lib/jquery.min.js")) Since this is evaluated right away I got an error as I tried to compile my Guix source checkout: error: failed to load 'gnu/packages/cran.scm': No such file or directory This error is highly misleading as it implies that “gnu/packages/cran.scm” could not be found, while the actual error is that “inst/htmlwidgets/lib/jquery.min.js” does not exist. This could be improved by catching 'system-error and reporting the file location instead of just printing the correct error message without context. -- Ricardo
