在R中安装r2excel包时遇到问题

Question

我正在尝试通过install_github在R中安装r2excel包，但收到以下错误

> install_github("kassambara/r2excel")

控制台中出现了几行代码，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

    xlsx.writeFile                          html  
    xlsx.writeMultipleData                  html  
** building package indices

* removing 'C:/Users/myusername/Documents/R/win-library/3.4/r2excel'
In R CMD INSTALL
Installation failed: Command failed (1)        

所以我在加载'xlsx‘时得到了这个错误

奇怪的是，我可以毫不费力地用

library(xlsx)

我安装了一个x64 java (内部版本1.8.0_161-b12)和一个运行的x64 rStudio，所以我真的不知道问题是从哪里来的。

根据https://github.com/kassambara/r2excel/issues/6中的六言古

“此程序包不是在64位系统中构建的，因此我们不能以这种方式安装它。但您仍然可以通过克隆存储库和源代码或仅复制粘贴"/R/r2excel.r”来使用所有功能。实际上不需要安装此程序包。“
