r - XML 安装似乎失败并且未在 R 上加载

问题描述

在安装并尝试加载一些用于生物数据分析的软件包时，我不断收到一条错误消息

Error: package or namespace load failed for ‘DESeq2’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
 there is no package called ‘XML’

然后我手动安装了 XML 包：

install.packages("XML")

它打印了这个：

There is a binary version available but the source version is later:
      binary   source needs_compilation
XML 3.99-0.4 3.99-0.5              TRUE
Do you want to install from sources the package which needs compilation? (Yes/no/cancel) yes

然后当我用库（XML）加载包时：

Error in library(xml) : there is no package called ‘xml’

许多其他包（如 data.table 等）都发生了这种情况

标签： rxml

解决方案

在您的情况下，C 编译器无法正常工作：

checking whether the C compiler works... no

尝试安装以前的版本（例如：）3.99-0.4和/或手动安装。

从 Cran 下载：https ://cran.r-project.org/src/contrib/Archive/XML/

您可以使用以下命令手动安装软件包

install.packages('package.tar.gz', lib='destination_directory_of_downloaded_package',repos = NULL)

请参阅 的帮助以?install.packages获取更多说明。

安装后检查包是否可用：

installed.packages()[1:5,]
