我正在尝试在R中使用cplexAPI，我得到了持续的错误。我正在使用MicrosoftROpen3.3.1，并在Windows 10上安装了ILOG优化Studio版本: 12.7.0.0。我要详细介绍一下，希望你能看到我的错误！

将tar文件解压缩到桌面上的文件夹中。
编辑文件：C:\Users\zejas\Desktop\cplexAPI\cplexAPI\src\Makevars.win，可以说：

 `PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"$C:\Program  Files\IBM\ILOG\CPLEX_Studio127\cplex\include"     PKG_LIBS=-L"$C:\Program Files\IBM\ILOG\CPLEX_Studio127\cplex\lib" -lm -lcplex1270`

微软在Reviron.site文件上做了自己的修改。他们在文件中添加了Rcmd_environ：C:\Program Files\Microsoft\MRO-3.3.1\etc\Rcmd_environ，我在文件中添加了最后三行：

 `## from R.sh     R_SHARE_DIR=${R_HOME}/share     R_INCLUDE_DIR=${R_HOME}/include     R_DOC_DIR=${R_HOME}/doc     R_ARCH=     ## from Rcmd     R_OSTYPE=windows     TEXINPUTS=.;${TEXINPUTS};${R_SHARE_DIR}/texmf/tex/latex;     BIBINPUTS=.;${BIBINPUTS};${R_SHARE_DIR}/texmf/bibtex/bib;     BSTINPUTS=.;${BSTINPUTS};${R_SHARE_DIR}/texmf/bibtex/bst;     ## from etc/Renviron     # R_PLATFORM='i386-pc-mingw32'     R_PAPERSIZE_USER=${R_PAPERSIZE}     R_PAPERSIZE=${R_PAPERSIZE-'a4'}     # for Rd2dpf, reference manual     R_RD4PDF=${R_RD4PDF-'times,inconsolata,hyper'}     ## used for options("texi2dvi")     # R_TEXI2DVICMD=${R_TEXI2DVICMD-${TEXI2DVI-'texi2dvi'}}     ## used by INSTALL, check, build     R_GZIPCMD=${R_GZIPCMD-'gzip'}     ## Default zip/unzip commands     R_UNZIPCMD=${R_UNZIPCMD-'unzip'}     R_ZIPCMD=${R_ZIPCMD-'zip'}     R_BZIPCMD=${R_BZIPCMD-'bzip2'}     ## Default browser     # R_BROWSER=${R_BROWSER-'open'}     ## Default editor     # EDITOR=${EDITOR-${VISUAL-vi}}     ## Default pager     # PAGER=${PAGER-''}     ## Default PDF viewer     # R_PDFVIEWER=${R_PDFVIEWER-'open'}     # MAKE=${MAKE-make}     SED=${SED-sed}     #     CPLEX_STUDIO_DIR=C:/Program Files/IBM/ILOG/CPLEX_Studio127      CPLEX_STUDIO_LIB=C:/Program Files/IBM/ILOG/CPLEX_Studio127/cplex/bin/x64_win64`

在Environment Variables System Variables Path中，我已经添加了：

 `%CPLEX_STUDIO_BINARIES127%;     C:\Program Files (x86)\Intel\OpenCL SDK\6.1\bin\x64;     C:\Program Files (x86)\Intel\OpenCL SDK\6.1\bin\x86;     C:\Program Files (x86)\Intel\OpenCL SDK\6.1\bin\Pin;     C:\Program Files (x86)\Intel\OpenCL SDK\6.1\bin\GTPin;     C:\ProgramData\Oracle\Java\javapath;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\bin;     C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\libnvvp;     C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;     C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;     C:\Windows\System32\WindowsPowerShell\v1.0\;     C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;     C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;     C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;     C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;     C:\Program Files (x86)\Skype\Phone\;     C:\Program Files\MATLAB\R2016b\bin;     C:\Program Files\MATLAB\R2016a\bin;     C:\Program Files\Microsoft\MRO-3.3.1\bin\x64;     C:\Users\zejas\.dnx\bin;C:\Program Files\Microsoft DNX\Dnvm\;     C:\Program Files\Microsoft SQL Server\130\Tools\Binn\;     C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;     C:\WINDOWS\system32;C:\WINDOWS;     C:\WINDOWS\System32\Wbem;     C:\WINDOWS\System32\WindowsPowerShell\v1.0\;     C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;     C:\Program Files\Git\cmd;     C:\Program Files\IBM\ILOG\CPLEX_Studio127\cplex\bin\x64_win64;     C:\Program Files\IBM\ILOG\CPLEX_Studio127\cplex\include;     C:\Rtools\bin`

我重建了这个包裹：

有什么想法吗？

使用@c0bra和@rkersh的输入进行更新

我更新Makevars.win

对我来说，您已经将$标记留在了Makevars.win文件的路径前面。请尽量纠正以下情况：

PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"C:\Program Files\IBM\ILOG\CPLEX_Studio127\cplex\include"
PKG_LIBS=-L"C:\Program Files\IBM\ILOG\CPLEX_Studio127\cplex\lib" -lm -lcplex1270

edit2:正如baydoganm所指出的，在cplex 1270中缺少两个功能。删除这些内容时，cplexAPI也可以使用windows进行编译：1.3.3.tar.gz

我有完全相同的问题，无法找到安装软件包的方法，尽管尝试了所有类似于这里的帖子。我不确定这个问题是否与软件包发布后CPLEX中的版本更改有关。

编辑:我确认了这个问题。显然，可调用的库元素addchannel、delchannel以及其他几个元素在12.7版本中被删除。以下是链接：

12.7.0/ilog.odms.cplex.help/CPLEX/ReleaseNotes/topics/releasenotes127/removed.html

在包的一个源文件中，已经提到了“ILOG版本的( 12.1到12.6)”。

看来降级会有帮助的。

在将CPLEX与R集成和安装cplexAPI包时，我遇到了类似的问题，请参阅https://cran.r-project.org/web/packages/cplexAPI/ --我正在做的错误很少，首先，问题的出现是因为R不知道在哪里安装了IBM，所以您必须手动更改在尝试从rstudio安装cplexAPI时下载的cplexAPI_1.3.3.tar.gz包中的文件Makevars.win。寻找以下代码：

PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"${CPLEX_STUDIO_DIR}\cplex\include"
PKG_LIBS=-L"${CPLEX_STUDIO_LIB}" -lm -lcplex1261

您需要检查的两件事是-L"${CPLEX_STUDIO_LIB}"被替换为-L"C:/Program Files/IBM/ILOG/CPLEX_Studio1271/cplex/bin/x64_win64" (参见bin/x64_bin 64)，也替换$

其次，在文件夹x64_win64中查找cplex12**.dll文件，这是-lcplex1261所指向的文件，这里手动将-lcplex1261更改为您的文件名(在我的例子中是cplex1271.dll，所以我将-lcplex1261更改为-lcplex1271，

同样，${CPLEX_STUDIO_DIR}必须由C:/Program Files/IBM/ILOG/CPLEX_Studio1271代替(在我的例子中)。

然后，按照https://www.r-bloggers.com/using-cplex-in-r-installing-cplexapi-in-windows-10/中给出的指令，使用以下命令(从命令行)重新打包和安装cplexAPI_1.3.3.tar.gz (确保安装了Rtools，并确保环境变量有指向R安装文件的路径，主要是通过R.exe和Rcmd.exe来运行命令)，以及

R CMD build --no-build-vignettes --no-manual --md5 C:\Users{computer name here}\Desktop\cplexAPI

R CMD INSTALL --build --no-multiarch .\cplexAPI_1.3.3.tar.gz
