我剛剛在AWS上啓動了一個EC2服務器,並試圖從 github安裝一個名爲'krose/skm'的包。該軟件包在Windows上安裝時沒有任何問題,但不在Ubuntu上安裝。所有依賴關係都已安裝。我無法弄清楚爲什麼它可以安裝在Windows上,但不是Ubuntu。Ubuntu上的命名空間導出(ns,exports)錯誤,但不是Windows
library(devtools)
install_github('krose/skm')
並運行上面的代碼的結果是:

UPDATE:將R CMD檢查具有以下兩個音符:
* checking DESCRIPTION meta-information ... NOTE
License components which are templates and need '+ file LICENSE':
MIT
* checking top-level files ... NOTE
Non-standard file/directory found at top level:
'README.Rmd'
R CMD檢查是在Windows上使用devtool :: check()函數進行的。 – KERO
