I need some help understanding a problem running the tests on the
'digest' package. Initially, I got the message that the 'knitr' package
was needed to run vignettes:
Running vignettes for package ‘digest’
Error in loadVignetteBuilder(vigns$pkgdir) :
vignette builder 'knitr' not found
So I installed the knitr package and all its dependents (‘mime’,
‘stringi’, ‘magrittr’, ‘evaluate’, ‘formatR’, ‘highr’, ‘markdown’,
‘stringr’, ‘yaml’) . Now I get some different warnings:
Running vignettes for package ‘digest’
Running ‘sha1.Rmd’
Warning messages:
1: In readLines(if (is.character(input2)) { :
cannot open file 'sha1.Rmd': No such file or directory
2: In engine$weave(file, quiet = TRUE, encoding = enc) :
The vignette engine knitr::rmarkdown is not available, because the
rmarkdown package is not installed. Please install it.
3: In readLines(con) :
cannot open file 'sha1.Rmd': No such file or directory
So why is sha1.Rmd missing? And why is it complaining about rmarkdown?
Or more precisely why did it not install it as a dependent? It installed
plain markdown.
