新手求助：go build时提示can't load package: package algorithms/qsort: cannot find package "algorithms/qsort" in any of:

在编译子函数时报错： D:\myprojects\sorter\src>go build algorithms/qsort can't load package: package algorithms/qsort: cannot find package "algorithms/qsort" in any of: C:\Go\src\algorithms\qsort (from $GOROOT) D:\myprojects\sorter\src\algorithms\qsort (from $GOPATH) 环境变量：D:\myprojects\sorter\src>echo %GOPATH% --> D:\myprojects\sorter; 目录结构： 我的源码： package qsort func quickSort(values []int, left, right int) { temp := values[left] p := left i, j := left, right for i <= j { for j >= p && values[j] >= temp { j-- } if j >= p { values[p] = values[j] p = j } if values[i] <= temp && i <= p { i++ } if i <= p { values[p] = values[i] p = i } } values[p] = temp if p-left > 1 { quickSort(values, left, p-1) } if right-p > 1 { quickSort(values, p+1, right) } } func QuickSort(values []int) { quickSort(values, 0, len(values)-1) } 请大家指点，感谢！
