在Windows 10的PowerShell中,`Get-AppxPackage` 是一个命令行工具,用于管理Windows Store应用程序的安装包。当你收到“因为当前用户未安装该程序包”这样的错误提示时,说明你在尝试运行某个依赖于商店应用的命令,而相应的应用程序并未在设备上安装。
通过执行 `Get-AppxPackage`,你可以查看设备上已安装的所有Windows Store应用及其相关信息,包括包名(Package Name)、版本号(Version),以及它们的状态(如是否已启用)。例如:
```powershell
Get-AppxPackage -AllUsers | Format-Table Name, Version, IsEnabled
```
这个命令会显示所有用户账户下的安装应用,并按名称、版本和启用状态排序。
如果你想要查找特定应用,可以在 `Get-AppxPackage` 后面加上应用的全名或者部分名称,比如:
```powershell
Get-AppxPackage -Name "Microsoft.WindowsCalculator"
```
如果发现缺少你需要的应用,你可以通过Windows Store手动下载并安装它。

在 Line 类中添加求两条线的交点和求点到线的距离的方法:
```
public Point getIntersection(Line line) {
double x1 = this.p1.x, y1 = this.p1.y;
double x2 = this.p2.x, y2 = this.p2.y;
double x3 = line.p1.x, y3 = line.p1.y;
double x4 = line.p2.x, y4 = line.p2.y;
double d = (x1 - x2) * (y3 - y4) - (y1 - y2) * (x3 - x4);
if (d == 0) {
return null;
}
double xi = ((x3 - x4) * (x1 * y2 - y1 * x2) - (x1 - x2) * (x3 * y4 - y3 * x4)) / d;
double yi = ((y3 - y4) * (x1 * y2 - y1 * x2) - (y1 - y2) * (x3 * y4 - y3 * x4)) / d;
return new Point(xi, yi);
}
public double getDistance(Point point) {
double x0 = point.x;
double y0 = point.y;
double x1 = this.p1.x;
double y1 = this.p1.y;
double x2 = this.p2.x;
double y2 = this.p2.y;
double a = y2 - y1;
double b = x1 - x2;
double c = x2 * y1 - x1 * y2;
double d = Math.abs(a * x0 + b * y0 + c) / Math.sqrt(a * a + b * b);
return d;
}
```
在 Test 类中测试求两个线的交点和求点到线的距离的方法:
```
Point p5 = new Point(0.5, 0.5);
Line l2 = new Line(p3, p4);
System.out.println("点到线的距离:" + l1.getDistance(p5));
Point intersection = l1.getIntersection(l2);
if (intersection != null) {
System.out.println("两条线的交点:" + intersection.x + "," + intersection.y);
} else {
System.out.println("两条线没有交点");
}
```
