我在尝试为 ROI (ROI.plugin.gurobi) 安装 gurobi 界面时遇到了困难。我已经在笔记本电脑上的 R（版本 1.4.1717）和 Gurobi 中安装了 gurobi、slam 和 SVN 包。

我尝试了以下安装 ROI.plugin.gurobi 的选项

remotes:::install_github("fl0sch/ROI.plugin.gurobi")

remotes:::install_github("FlorianSchwendinger/ROI.plugin.gurobi")


**Error message:**

*** arch - i386
Error: package or namespace load failed for 'ROI.plugin.gurobi' in library.dynam(lib,package,package.lib):
 DLL 'gurobi' not found: maybe not installed for this architecture?
Fehler: Laden fehlgeschlagen
Ausführung angehalten
*** arch - x64

remotes:::install_svn("svn://svn.r-forge.r-project.org/svnroot/roi/pkg/ROI.plugin.gurobi")

**Error:** Failed to install 'unknown package' from SVN:
  SVN does not seem to be installed on your system.

install.packages("ROI.plugin.gurobi",repos="http://R-Forge.R-project.org")
Warning in install.packages :
  package ‘ROI.plugin.gurobi’ is not available for this version of R

**Error message:**

A version of this package for your version of R might be available elsewhere,see the ideas at
https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages

有人可以指出我的错误方向和可能的解决方案吗？

如果我缺少回答问题所需的任何信息，请告诉我。

谢谢！
