Dear R Developers, I am having an issue with the renv package and R 4.0.1, which I suspect is related to base R and not the renv package itself, as with R 3.6.3 such an "error" does not appear.
The error is raised by a file.exists() path, and path "C:\Users\J-tel\Documents", which in R 3.6.3 is read correctly, but in R 4.0.1 fails (Probably because of the "-" symbol), and I suspect it might be related with the new UTF-8 usage on Windows 10? (https://developer.r-project.org/Blog/public/2020/05/02/utf-8-support-on-windows/index.html) I have also checked file.exists() function and its internals, and seem not to have happened changes in the meanwhile within them: https://github.com/wch/r-source/blob/0e3b3182f87a60af4b0293a5410dde680b910f49/src/library/base/R/files.R https://github.com/search?q=SEXP%20attribute_hidden%20do_fileexists+repo:wch/r-source&type=Code Error Details: > renv::init() Error in file.exists(children) : file name conversion problem -- name too long? > traceback() 14: file.exists(children) 13: renv_dependencies_find_dir_children(path, root) 12: renv_dependencies_find_dir(path, root) 11: FUN(X[[i]], ...) 10: lapply(path, renv_dependencies_find_impl, root = root) 9: renv_dependencies_find(path, root) 8: (function (path = getwd(), root = NULL, ..., progress = TRUE, errors = c("reported", "fatal", "ignored"), dev = FALSE) { path <- renv_path_normalize(path, winslash = "/", mustWork = TRUE) root <- root %||% renv_dependencies_root(path) if (exists(path, envir = `_renv_dependencies`)) return(get(path, envir = `_renv_dependencies`)) renv_dependencies_begin(root = root) on.exit(renv_dependencies_end(), add = TRUE) dots <- list(...) if (identical(dots[["quiet"]], TRUE)) { progress <- FALSE errors <- "ignored" } files <- renv_dependencies_find(path, root) deps <- renv_dependencies_discover(files, progress, errors) renv_dependencies_report(errors) deps })(path, progress = FALSE, errors = errors, dev = TRUE) 7: eval(call, envir = parent.frame(2)) 6: eval(call, envir = parent.frame(2)) 5: delegate(renv_dependencies_impl) 4: dependencies(path, progress = FALSE, errors = errors, dev = TRUE) 3: withCallingHandlers(dependencies(path, progress = FALSE, errors = errors, dev = TRUE), renv.dependencies.error = renv_dependencies_error_handler(message, errors)) 2: renv_dependencies_scope(project, action = "init") 1: renv::init() > renv::diagnostics() Diagnostics Report -- renv [0.10.0] =================================== # Session Info ======================= R version 4.0.1 (2020-06-06) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 10 x64 (build 18362) Matrix products: default locale: [1] LC_COLLATE=Spanish_Spain.1252 LC_CTYPE=Spanish_Spain.1252 [3] LC_MONETARY=Spanish_Spain.1252 LC_NUMERIC=C [5] LC_TIME=Spanish_Spain.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] renv_0.10.0 loaded via a namespace (and not attached): [1] compiler_4.0.1 rsconnect_0.8.16 htmltools_0.4.0 tools_4.0.1 [5] yaml_2.2.1 Rcpp_1.0.4.6 rmarkdown_2.2 knitr_1.28 [9] xfun_0.14 digest_0.6.25 packrat_0.5.0 rlang_0.4.6 [13] evaluate_0.14 # Project ============================ Project path: "~/Test2" # Status ============================= # Lockfile =========================== This project has not yet been snapshotted: 'renv.lock' does not exist. # Library ============================ The project library "~/Test2/renv/library/R-4.0/x86_64-w64-mingw32" does not exist. # Dependencies ======================= # User Profile ======================= [no user profile detected] # Settings =========================== List of 6 $ external.libraries : chr(0) $ ignored.packages : chr(0) $ package.dependency.fields: chr [1:3] "Imports" "Depends" "LinkingTo" $ snapshot.type : chr "implicit" $ use.cache : logi TRUE $ vcs.ignore.library : logi TRUE # Options ============================ List of 1 $ renv.verbose: logi TRUE # Environment Variables ============== HOME = C:\Users\J-tel\OneDrive\Documents LANG = <NA> R_LIBS = <NA> R_LIBS_SITE = <NA> R_LIBS_USER = C:/Users/J-tel/OneDrive/Documents/R/win-library/4.0 # PATH =============================== - C:\rtools40\usr\bin - C:\Program Files\R\R-4.0.1\bin\x64 - C:\ProgramData\Miniconda3 - C:\ProgramData\Miniconda3\Library\mingw-w64\bin - C:\ProgramData\Miniconda3\Library\usr\bin - C:\ProgramData\Miniconda3\Library\bin - C:\ProgramData\Miniconda3\Scripts - C:\ProgramData\Oracle\Java\javapath - C:\WINDOWS\system32 - C:\WINDOWS - C:\WINDOWS\System32\Wbem - C:\WINDOWS\System32\WindowsPowerShell\v1.0\ - C:\WINDOWS\System32\OpenSSH\ - C:\Program Files\MiKTeX 2.9\miktex\bin\x64\ - C:\ProgramData\Miniconda3\Scripts\conda.exe # Cache ============================== There are a total of 0 package(s) installed in the renv cache.
