我无法升级npm安装。

我尝试安装新版本的npm：

1.Step

npm install npm -g

npm install npm --save-dev

2.Step

npm outdated 

Package  Current  Wanted  Latest
npm        3.5.3   3.5.4   3.5.3

的package.json

{
  "name": "tiko",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
  }
}

npm更新无效吗？

您可以使用private void ShowRoute(IEnumerable<Point> path, int size) { Canvas myCanvas1 = new Canvas(); Canvas myCanvas2 = new Canvas(); for (int y = 0; y <= this.map.GetLength(1)-1; y++) { for (int x = 0; x < this.map.GetLength(0); x++) { //set the initial point if (this.searchParameters.StartLocation.Equals(new Point(x, y))) { myCanvas1.Background = new SolidColorBrush(Colors.Red); myCanvas1.Height = size; myCanvas1.Width = size; Canvas.SetTop(myCanvas1, (y) * size); Canvas.SetLeft(myCanvas1, (x) * size); myParentCanvas.Children.Add(myCanvas1); } //set the end point else if (this.searchParameters.EndLocation.Equals(new Point(x, y))) { myCanvas2.Background = new SolidColorBrush(Colors.Blue); myCanvas2.Height = size; myCanvas2.Width = size; Canvas.SetTop(myCanvas2, (y) * size); Canvas.SetLeft(myCanvas2, (x) * size); myParentCanvas.Children.Add(myCanvas2); } //add the whole path to a list else if (this.map[x, y] == true) { if (path.Where(p => p.X == x && p.Y == y).Any()) { Mapa pathToGo = new Mapa(); pathToGo.x = x; pathToGo.y = y; Mapa.mapaCamino.Add(pathToGo); } } } } //show the path in the map foreach (var camino in Mapa.mapaCamino) { ImageBrush yellowDot = new ImageBrush(); yellowDot.ImageSource = new BitmapImage(new Uri("ms-appx:/Imagenes/pathToOz.png", UriKind.Absolute)); Canvas myCanvas3 = new Canvas(); myCanvas3.Background = yellowDot; myCanvas3.Height = (size + 2); myCanvas3.Width = (size + 2); Canvas.SetTop(myCanvas3, (camino.y) * size); Canvas.SetLeft(myCanvas3, (camino.x) * size); myParentCanvas.Children.Add(myCanvas3); } showAnimation(size); }本身更新npm安装。

您需要安装最新版本的npm作为全局包：

npm
