Question

我正在尝试使用功能区：Tools--> Install Packages --> Packages:将XML软件包安装到Rstudio，但键入的XML下拉列表仅包含以下软件包：xml2，XML2R，xml2relational，xmlparsedata，xmlr，xmlrpc2。

接下来，我尝试了：

install.packages("XML")

但收到警告：

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

https://cran.rstudio.com/bin/windows/Rtools/
Installing package into ‘D:/BCDD/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)
Warning in install.packages :
  package ‘XML’ is not available (for R version 3.6.3)

所以我点击了上面的链接：https://cran.rstudio.com/bin/windows/Rtools/ 并使用以下问题：

然后尝试

install.packages("XML", repos = "http://www.omegahat.net/R",type="source")

但收到相同的警告，甚至更多：

任何对如何安装XML包的帮助都会感激

Answer 1

您可以从此处下载所需的版本：https://cran.rstudio.com//src/contrib/Archive/XML/

根据他们的GitHub存储库，版本3.99-0.3应该适合您，我无法尝试，因为我有R4.0，并且只能安装最新的[3.99-0.5]。

或者，当您选择所需的版本并在R控制台上运行时：

devtools::install_version("XML", version = "3.99-0.3") # or the version you want

尝试一下。让我知道。

Answer 2

选中此RStudio Support post ，其中介绍了如何安装旧版软件包。

请确保从archive上安装rtools35

此时，转到R 4.0.2并不是一个特别糟糕的主意。

无法将XML软件包安装到Rstudio
