我已经安装了 Microsoft R 客户端。当我从 shell 运行 R 时，我得到
Microsoft R Open 3.4.3

但是，当我从 Rstudio-server 运行 R 时，我只得到
Microsoft R Open 3.4.3

系统只有一个 R 的副本，并且它与库路径一起正确指定在rserver.conf
cat /etc/rstudio/rserver.conf
# Server Configuration File
rsession-which-r=/usr/bin/Revo64
rsession-ld-library-path=/opt/microsoft/rclient/3.4.3/libraries/RServer
在 Rstudio R 环境中，库路径就在那里
>.libPaths()
[1] "/home/xyz/R/x86_64-pc-linux-gnu-library/3.4"
[2] "/opt/microsoft/rclient/3.4.3/runtime/R/library"
但是，RevoScaleR不会自动加载。当我尝试手动加载它时，我得到
> library(RevoScaleR)
Fehler in library(RevoScaleR) : es gibt kein Paket namens ‘RevoScaleR’
有人知道可能出了什么问题吗？
