r - R packge install from GitHub - "'' does not exist in current working directory
问题描述
I have built a new package, and it is hosted on GitHub at github.com/kevinwolz/hisafer.
I am trying to install the package via devtools::install_github(), but I am getting aweird error. Help?

It seems that the critical error here is "Error : '' does not exist in current working directory". Does anyone know why this might be happening? Is there something about the way my package is built/setup that is causing issues? I can install the package from source just fine when not downloading from GitHub, so that leads me to believe that something weird is happening in the GitHub process.

解决方案
问题在于R/utils.R
,您尝试从中读取inst/extdata
不存在的文件(这是从第 36 行和第 37 行开始):
INPUT.DEFS <- readr::read_delim(system.file("extdata", "input_defs.txt", package = "hisafer"), "\t", col_types = readr::cols())
OUTPUT.DEFS <- dplyr::arrange(readr::read_delim(system.file("extdata", "output_defs.txt", package = "hisafer"), "\t", col_types = readr::cols()), profile, name)
检查inst/extdata
会显示你既不input_defs.txt
也不output_defs.txt
存在。
我是怎么想出来的?
我跑了
devtools::load_all("hisafer/")
这也给出了错误
错误:当前工作目录中不存在“”
但允许您显示信息回溯:
13.stop("'", path, "' does not exist", if (!is_absolute_path(path)) paste0(" in current working directory ('",
getwd(), "')"), ".", call. = FALSE)
12.check_path(path)
11.standardise_path(file)
10.read_delimited(file, tokenizer, col_names = col_names, col_types = col_types,
locale = locale, skip = skip, comment = comment, n_max = n_max,
guess_max = guess_max, progress = progress)
9.readr::read_delim(system.file("extdata", "input_defs.txt", package = "hisafer"),
"\t", col_types = readr::cols()) at utils.R#36
8.eval(exprs[i], envir)
7.eval(exprs[i], envir)
6.source_one(file, envir = envir)
5.source_many(paths, env)
4.force(code)
3.withr_with_dir(file.path(pkg$path), source_many(paths, env))
2.load_code(pkg)
1.devtools::load_all("hisafer/")
注意回溯中的第 9 号,它不仅显示了有问题的代码,而且还有助于显示它来自哪个文件以及它在哪一行。
问题根源:你的.gitignore
在你的.gitignore
,你有线条
inst/extdata/
inst/extdata/*
这意味着其中的所有文件和子文件夹inst/extdata/
都不会被跟踪,因此当用户尝试从 GitHub 安装时,他们没有获得让extdata/
您的包正常工作所需的文件。
附带说明一下,即使用户下载了您的存储库并手动添加了input_defs.txt
and output_defs.txt
,出于同样的原因,他们也不会有您希望他们拥有的其他模板目录,因此构建小插图会导致安装错误。
