未在Windows计算机上安装Composer

Question

我对Web开发非常陌生，并且大多遵循教程，因此，我正在学习laravel，并且想安装composer。我从composer网站下载了安装程序，并在我使用xampp的环境变量中手动添加了PHP路径。当我运行安装程序时，出现此错误

“由于未下载composer.phar，因此Composer安装程序脚本无法正确运行。”

2种修复方法，

1. 在cmd中运行以下命令：

   Public Class inventory Public Property id As Integer Public Property name As String 'I added a custom constructor to make filling a list easier for me Public Sub New(i As Integer, n As String) id = i name = n End Sub 'add back default constructor Public Sub New() End Sub End Class Private orders As New List(Of inventory) From {New inventory(1, "Apples"), New inventory(2, "Oranges"), New inventory(3, "Pears")} Private Sub OPCode() Dim rrr As String = "name" 'Console.ReadLine() as if user typed in name For Each i In orders Console.WriteLine(GetPropertyValue(i, rrr)) Next End Sub Private Function GetPropertyValue(src As Object, PropName As String) As Object Return src.GetType().GetProperty(PropName).GetValue(src, Nothing) End Function

2. 卸载然后重新安装并以管理员身份运行（如果在Windows上，请运行.exe）

第一个固定地雷一次。
