Docker install.packages R on Ubuntu 22.04 找不到包

Question

我有 docker 命令來安裝 R 包：

RUN R -e "install.packages(c("readxl","zoo","plotly","RcppRoll","shiny","tidyverse"\
,"shinyWidgets","shinythemes","metR","writexl","shinydashboard","lubridate","sjmisc"\
,"DBI","dplyr","dbplyr","odbc"), repos='https://cloud.r-project.org/')"

我得到錯誤

install.packages(c(readxl,zoo,plotly,RcppRoll,shiny,tidyverse,shinyWidgets,shinythemes,metR,writexl,shinydashboard,lubridate,sjmisc,DBI,dplyr,dbplyr,odbc),repos='https://cloud. r-project.org/') install.packages(c(readxl, zoo, plotly, RcppRoll, shiny, tidyverse, : object 'readxl' not found Execution halted 錯誤

錯誤在哪里？ R 在沒有 docker 的情況下運行良好。

Answer 1

您正在成為 shell 引用的受害者，有時稱為 shell 引用地獄。 事實上，正如你所說，“R 在沒有 docker 的情況下運行良好”只是意味着你在 R 中有正確的命令，但不是來自 shell。見證

$ Rscript -e "cat("Hello, world\n")"
Error: unexpected end of input
Execution halted
$ 

但是（方法 1）escaping 引用有效：

$ Rscript -e "cat(\"Hello, world\n\")"
Hello, world
$ 

或（方法 2）用單引號將雙引號括起來

$ Rscript -e 'cat("Hello, world\n")'
Hello, world
$ 

所以我會嘗試

RUN R -e 'install.packages(c("readxl","zoo","plotly","RcppRoll","shiny", 
          "tidyverse",    "shinyWidgets","shinythemes","metR","writexl",
          "shinydashboard","lubridate","sjmisc", "DBI", "dplyr", 
          "dbplyr", "odbc"), repos="https://cloud.r-project.org/")'

另外，您可能還想查看r2u以在 Ubuntu 22.04 或 20.04 上將所有這些作為二進制文件 (..) 完成。
