在 R 中运行 renv 包

Question

我正在尝试执行 renv::snapshot() 并且我得到了

Error in file.exists(children) : 
  file name conversion problem -- name too long?

我在 Windows 10 上，我找不到项目的 dir 路径名（C:\Users\alber\OneDrive\Documentos\R\manual）有任何问题。

还能是什么？

编辑 - renv::diagnostics()

Obs.：由于我的项目位于 OneDrive 文件夹中，我可以在另一台机器上打开它并且它工作正常。 我注意到在另一台机器中项目路径已满 (C:/...) 而在这台机器中它以 ~/.也许就是这样？

看来您的问题是由于某些软件包依赖项安装在path with non-English characters 中。

https://github.com/rstudio/renv/blob/9298efabca69803bb808a4bc3c3311b5c98f706f/R/dependencies.R#L265

# return the set of files / subdirectories within a directory that should be
# crawled for dependencies
renv_dependencies_find_dir_children <- function(path, root) {

  # list files in the folder
  children <- renv_file_list(path, full.names = TRUE)

  # remove files which are broken symlinks
  children <- children[file.exists(children)]

  # remove hard-coded ignores
  ignored <- c("renv")
  children <- children[!basename(children) %in% ignored]

  # construct pattern for matching files in this path
  # (return all files if no such pattern available)
  renv_renvignore_exec(path, root, children)

}
