當你去包文檔的一些錯誤發生：https://cran.r-project.org/web/packages/Rcplex/index.html ...你沒有提到的滿意系統要求：

SystemRequirements: IBM ILOG CPLEX libraries and headers

我有軟件CPLEX。但仍然無法安裝那麼該軟件包不能用於Windows？ –

您可以在不使用R的情況下運行CPLEX代碼嗎？ http://www.ibm.com/support/knowledgecenter/SSSA5P_12.6.3/ilog.odms.studio.help/Optimization_Studio/topics/COS_relnotes_intro.html –

是的，我可以！你會知道什麼是錯的嗎？ –

是gcc用途，ld，找不到CPLEX共享庫的鏈接。根據INSTALL文檔，您需要驗證CPLEX_LIB_PATH被定義爲指向CPLEX dll所在的路徑。從你的輸出中，我願意冒險

set CPLEX_LIB_PATH="C:/Program Files/IBM/ILOG/CPLEX_Studio_Community1263/cplex/lib"

是你需要的。
