R-devel 与摇杆消毒剂

Question

我正在尝试使用来自 rocker 的 ASAN USBAN 安装 R devel。按照我尝试的自述文件：

sudo docker run --rm -ti rocker/r-devel-san

这个下载的时间比较长，不过最后还是可以的。然后我安装了 sanitizers 包以针对已知错误测试 R。

install.package("sanitizers")

然后我尝试得到一个错误

> sanitizers::stackAddressSanitize(42)
[1] 24
> sanitizers::heapAddressSanitize(1)
[1] 0

我没有收到任何错误，所以我猜我运行 docker 的 R 版本不支持消毒剂。或者我只是错过了某处的东西。这是我第一次 docker.

确保你开始 RD 而不是 R。然后它按预期对我有用：

简而言之，就像在 r-devel 容器中一样，您想要的非香草版本是 RD 而不是 R，后者是标准二进制包中的普通香草 R。
