前言

前端时间抽时间看完了Go基础的一些内容，后面接着学习，记录一些错误。

错误

cannot refer to unexported name fmt.println

报错信息:

代码语言：javascript复制
# basic
.main.go:6:2: cannot refer to unexported name fmt.println    //不能够引用未导出的名称fmt.println
.main.go:6:2: undefined: fmt.println    //未定义的:fmt.println

原因:

嗯，Go中其实有规定的就是模块中要导出的函数，必须首字母大写，所以错误的原因就是fmt.Println()写成了fmt.println()

go get 报错 cc1.exe: sorry, unimplemented: 64-bit mode not compiled in

报错信息:

代码语言：javascript复制
D:wampwwwGoLearn>go get github.com/mattn/go-sqlite3
# github.com/mattn/go-sqlite3
cc1.exe: sorry, unimplemented: 64-bit mode not compiled in

原因:

GCC编译器版本不是64位的,访问https://sourceforge.net/projects/mingw-w64/下载个64位的把环境变量配置好,安装教程https://www.cnblogs.com/findumars/p/8289669.html
