r - 我在安装 R 包时遇到问题。每当我尝试安装时，都会收到一条非零状态的错误消息。是什么原因？

问题描述

我试图安装重新思考的 R 包。但是，我无法安装该软件包。每当我安装时，R 都会下载该软件包，但由于某种原因无法安装。我什至尝试了包的直接网站，但我最终遇到了同样的问题。我还尝试了另一个包“timetk”。但是，我遇到了同样的错误。让我知道问题所在。谢谢。

解决方案

当您看到消息“finding level-2 HTML links ...”时，程序包生成器正在运行tools::findHTMLlinks(level=2)以查找帮助文件之间的链接。通常，链接信息在包内缓存为 RDS 文件。这是您可以运行以检查错误可能来自何处的函数运行的代码的变体

check_rds <- function(rds) {tryCatch({readRDS(rds); TRUE}, error=function(x) {FALSE})}

for (x in rev(dir(.libPaths(), full.names = TRUE))) {
  is_ok <- if (file_test("-f", f <- file.path(x, "Meta", "links.rds")))
    check_rds(f)
  else if (file_test("-f", f <- file.path(x, "Meta", "Rd.rds")))
    check_rds(f)
  else TRUE
  if (!is_ok) {
    print(paste("bad file", x, f)); 
  }
}

它应该打印它找到的所有坏 RDS 文件。如果没有打印任何内容，则错误必须在其他地方。但如果它确实识别出一个坏文件，那么我建议卸载该特定软件包并重新安装它。
