我正在尝试通过 install_github 在 R 中安装 r2excel 包，但出现此错误

> install_github("kassambara/r2excel")

控制台中出现几行，我得到

* installing *source* package 'r2excel' ...
** R
** preparing package for lazy loading
Warning: package 'xlsx' was built under R version 3.4.4
** help

所以我在“xlsx”加载时收到这个错误
奇怪的是我没有问题单独加载“xlsx”和“rJava” 

library(xlsx)

我安装了 x64 java（构建 1.8.0_161-b12）和运行 x64 rStudio，所以我真的不知道问题出在哪里。

根据 liuyanguu 在https://github.com/kassambara/r2excel/issues/6：

“这个包不是在 64 位系统中构建的，所以我们不能这样安装。但是你仍然可以通过克隆 repo 和源或复制粘贴“/R/r2excel.r”来使用所有功能。实际上没有需要安装包。”
