backports 1.1.1 包安裝失敗

Question

我無法公開我的 R 筆記本。 當我嘗試發布時，出現以下錯誤：

Console~/

    .../R Test 1/Fall Programming with R Test 1.Rmd     
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : 
  there is no package called 'backports'

Execution halted

我嘗試安裝 backports，但它似乎也不起作用。 當我嘗試安裝 backports 時出現此錯誤：

> install.packages("backports")

(as ‘lib’ is unspecified)

  There is a binary version available but the source version is later:

Answer 1

我在backports R 包中遇到了類似的錯誤。 它阻止了devtools包安裝我編寫的自定義包。

我通過安裝以前版本的backports修復它：

require(devtools)
install_version("backports", version = "1.1.0")

Answer 2

我解決了它重新安裝 Rtools（我正在運行 Windows）。
