操作系统：Windows 7 x64
R安装：2.15.1 x64
Cplex instalation：Cplex Studio Academic 124（32位和64位）
我安装了Rtools，我有一个独立的cygwin安装，包含所有必需的软件包。我也有MikTex安装...
我设置了以下环境标志......
CPLEX_PATH=C:\Program Files\IBM\ILOG\CPLEX_Studio_Academic124
CPLEX_STUDIO_DIR=C:\Program Files\IBM\ILOG\CPLEX_Studio_Academic124
CPLEX_STUDIO_LIB32=C:\Program Files (x86)\IBM\ILOG\CPLEX_Studio_Academic124\opl\bin\x86_win32;C:\Program Files (x86)\IBM\ILOG\CPLEX_Studio_Academic124\opl\oplide\;C:\Program Files (x86)\IBM\ILOG\CPLEX_Studio_Academic124\cplex\bin\x86_win32;C:\Program Files (x86)\IBM\ILOG\CPLEX_Studio_Academic124\cpoptimizer\bin\x86_win32
CPLEX_STUDIO_LIB64=C:\Program Files\IBM\ILOG\CPLEX_Studio_Academic124\opl\bin\x64_win64;C:\Program Files\IBM\ILOG\CPLEX_Studio_Academic124\opl\oplide\;C:\Program Files\IBM\ILOG\CPLEX_Studio_Academic124\cplex\bin\x64_win64;C:\Program Files\IBM\ILOG\CPLEX_Studio_Academic124\cpoptimizer\bin\x64_win64
然后当我在R中运行install命令时，我得到以下错误
> install.packages("c:/cplexAPI_1.2.2.tar.gz", type="source")
