dplyr.snowflakedb是否仅在32位JDK上运行？

Question

我无法在Windows 10 64位PC上安装软件包。我已经安装了R的最新版本，这是安装RJDBC所必需的，并且rJava可以在我依赖的所有其他软件包上加载和运行，而没有任何问题。以下是运行一些检查的结果：

> sessionInfo()
R version 3.6.2 (2019-12-12)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 10 x64 (build 18363)

Matrix products: default

> Sys.getenv("JAVA_HOME")

> library(rJava)
> .jinit()
> .jcall("java/lang/System", "S", "getProperty", "java.runtime.version")
[1] "13.0.2+8"

但是，当我尝试安装该软件包时，失败如下：

仅当您安装了32位版本的JDK时，程序包才起作用吗？但是我被告知，如果您正在运行64位版本的R，则无法在32位Java安装中运行rJava。

FYI：看来这在git存储库问题中已解决：https://github.com/snowflakedb/dplyr-snowflakedb/issues/1#issuecomment-239830188
