从RStudio中我试图在these instructions之后从github安装data.table包,并且包似乎下载没有问题:
> library(devtools)
> dev_mode(on=T)
Dev mode: ON
d> install_github("Rdatatable/data.table")
Downloading GitHub repo Rdatatable/data.table@master
from URL https://api.github.com/repos/Rdatatable/data.table/zipball/master
然后我收到以下提示:
从源代码构建R包需要安装额外的 构建工具。您想现在安装其他工具吗?
选择"是"导致此错误消息:
Error: Could not find build tools necessary to build data.table
认为这可能是一个RStudio问题,我尝试在标准R控制台中安装软件包,但这也导致了错误:

我在SO上发现了三个相关帖子:
Error: Could not find build tools necessary to build dplyr
Error : Could not find build tools necessary to build
Could not find build tools necessary . Facing error with devtools
前两个似乎特定于Apple OS,第三个表示devtools特有的错误,但我不知道这是否是我看到的错误的来源。
任何帮助将不胜感激。我在Windows 10中运行R版本3.3.0。

您可以尝试:
options(buildtools.check = function(action) TRUE )
中
...应该禁止RStudio尝试验证您的构建工具。
对我有用。
