我是 lp 解决的新手。我正在尝试运行以下代码并收到以下错误：

    package package1;

/**

 */

import lpsolve.*;

public class Demo {

    public static void main(String[] args) {
        try {
            // Create a problem with 4 variables and 0 constraints
            LpSolve solver = LpSolve.makeLp(0, 4);

            // add constraints
            solver.strAddConstraint("3 2 2 1", LpSolve.LE, 4);
            solver.strAddConstraint("0 4 3 1", LpSolve.GE, 3);

            // set objective function
            solver.strSetObjFn("2 3 -2 3");

            // solve the problem
            solver.solve();

            // print solution
            System.out.println("Value of objective function: " + solver.getObjective());
            double[] var = solver.getPtrVariables();
            for (int i = 0; i < var.length; i++) {
                System.out.println("Value of var[" + i + "] = " + var[i]);
            }

            // delete the problem and free memory
            solver.deleteLp();
        }
        catch (LpSolveException e) {
            e.printStackTrace();
        }
    }

}

错误：

您确定使用 System.loadlibrary 在其他类中加载正确的库吗？

如果是，我认为快速解决方案可以将所有库放在 os PATH 中存在的文件夹中（例如 system32、windows）如果没有任何其他问题，这对我每次都有效
