【问题标题】：R install pacakages error (escape in character string) in Library PathR在库路径中安装包错误（字符串中的转义）

【问题描述】：

我已尝试编辑 .libpaths() 的输出并对其进行更改，但我仍然收到以下错误，

PS C:\Users\Jesus> radian
Error: '\D' is an unrecognized escape in character string starting "'D:\D"
R version 4.1.2 (2021-11-01) -- "Bird Hippie"
Platform: x86_64-w64-mingw32 (64-bit)

如果您注意到'\D' is an unrecognized escape in character string starting "'D:\D" 即使在我切换到弧度时也很明显。

r$> .libPaths()
[1] "D:/Documents/R/win-library/4.1"     "C:/Program Files/R/R-4.1.2/library"

r$> remotes::install_github("ManuelHentschel/vscDebugger")

我收到此错误Error: '\D' is an unrecognized escape in character string starting "'D:\D" 我认为它只发生在我尝试安装的特定软件包上。

如果有人知道如何解决这个问题，那么我可以在 VSCode 上进行 R 调试。

谢谢。

【解决方案1】：

我发现我的.Rprofile 有问题查看其他论坛，删除您的 .Rdata 文件似乎也有帮助。

它生成为

# LanguageServer Setup Start (do not change this chunk)
# to remove this, run languageserversetup::remove_from_rprofile
if (requireNamespace('languageserversetup', quietly = TRUE)) {
  options(langserver_library = 'D:\Documents/languageserver-library')
  languageserversetup::languageserver_startup()
  unloadNamespace('languageserversetup')
}
# LanguageServer Setup End

修复方法是将'D:\Documents/languageserver-library' 中的\ 更改为/

如'D:/Documents/languageserver-library'

干杯
