Question

它不会加载库。

setwd("C:/Users/***/Desktop")
install.packages('ROracle_1.2-1.zip', repos = NULL)
#Installing package into ‘C:/Users/***/Documents/R/win-library/3.3 (as ‘lib’ is unspecified)

#package ‘ROracle’ successfully unpacked and MD5 sums checked

library('ROracle')
#Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared object 'C:/Users/***/Documents/R/win-library/3.3/ROracle/libs/x64/ROracle.dll': LoadLibrary failure:  The specified module could not be found.

我手动检查了文件路径，ROracle.dll就在那里。

编辑：

我有RODBC和RJDBC工作。我只是不明白为什么不会安装ROracle：

library(ROracle)

我猜测有些Oracle文件需要安装，但没有一个文档非常清楚。

Answer 1

为了正确安装和加载ROracle，您应该拥有Oracle Client 64位和Windows 64位。在我的计算机上安装64位Oracle客户端后，此错误就消失了。

R连接到Oracle - 库（ROracle）失败
