* .o：Windows 7无法识别文件格式

我写了一个名为 arbintools的R软件包,用于一些与工作相关的数据分析,并把它放在 Github上.我写了它并且已经在我的Mac上使用它一段时间没有问题;今天,我尝试在Windows 7笔记本电脑上安装 dev-1 branch,并且编译一些Rcpp功能的相关内容似乎出错了：

devtools::install_github("mjlacey/arbintools",ref = "dev1")

我明白了：

安装其他需要编译的软件包(如dplyr)工作正常.我还在我的Mac上将R更新为相同版本(3.3.0)并成功重新安装了软件包,它只是在Windows PC上无法正常工作.这超出了我的理解,如果有人有任何建议或解决方案,我将非常感激.
