初次接触Go语言，便遭遇挑战，面对"hello world"的简单示例却无法顺利运行，面对"package command-line-arguments is not a main package"的报错，不禁眉头紧锁。究其原因，是在IDE工具创建文件时，将package包名设为文件夹名，而运行时，Go语言仅识别以"main"命名的包作为执行入口。因此，需将package名称...
报错一: package command-line-arguments is not a main package(包命令行参数不是主包) 原因:IDE工具在创建文件的时候会自动将package包名写为文件夹的名字,但是我们用go run 运行的时候只能识别main作为包运行入口,所有我们需要将package 更改为main package main表示一个可独立执行的程序,每个 Go 应用程序都包含...

在构建我的一个包时,具体错误是: start.go: package project/game is not in GOROOT (C:\Go\src\project\game)
