通過pip在Python 2.7（Windows 10）上安裝PySCIPOpt不起作用

Question

我只是嘗試通過執行“ pip install pyscipopt”來通過pip安裝PySCIPOpt，但是出現以下錯誤消息：

我究竟做錯了什么？

我在64位Windows 10計算機上運行Python 2.7。 它不會讓我發布這樣的問題，因此我從下面的錯誤消息中刪除了一些明顯的部分。

它仍然不讓我發布問題，因此這里還有一些文字，也許現在可以了。 仍然沒有。 也許現在？

Answer 1

這個問題已經在這里得到回答： https : //github.com/SCIP-Interfaces/PySCIPOpt/issues/102

除了安裝SCIP Opt Suite之外，缺少的是設置SCIP Opt Suite的安裝路徑：

set SCIPOPTDIR="C:\Program Files\SCIPOptSuite"

或類似的東西。

Answer 2

安裝說明說：

SCIPOPTDIR需要具有包含該庫的子目錄lib。

另外，如果要從源代碼構建PySCIPOpt，即不使用預編譯的egg或wheel，則還需要將所有SCIP頭文件放入lib旁邊的目錄中（此操作由make install INSTALLDIR = $ SCIPOPTDIR SHARED =自動完成。適用於SCIP優化套件）

因此，首先您需要安裝SCIP Optimization Suite。
