我是R和RStudio的新手,但他正在努力学习并整理一个ShinyApps应用程序.我无法通过Shinyapps进程的第1步,即在RStudio中安装devtools包.我认为根本原因是没有安装"xml2"软件包依赖项,但我似乎无法解决这个问题而且我不明白该怎么做.
我在戴尔笔记本电脑上使用Linux Mint Cinnamon 17.1.我从软件管理器安装了RStudio.在试图解决devtools安装过程中的错误,我已经尝试使用安装R和RStudio从稍微更新包下载apt-get的,我已经尝试安装xml2和rversions从RStudio(不可用),我试着用单引号和双引用,我已经尝试添加dependency=true到所有RStudio安装尝试,我已经多次重启RStudio和机器......我没有想法......帮助？
以下是RStudio中devtools安装命令的输出,加上"版本"的输出以防万一.
