Go——報錯總結

前言

前端時間抽時間看完了Go基礎的一些內容，后面接着學習，記錄一些錯誤。

錯誤

cannot refer to unexported name fmt.println

報錯信息:

# basic
.\main.go:6:2: cannot refer to unexported name fmt.println    //不能夠引用未導出的名稱fmt.println
.\main.go:6:2: undefined: fmt.println    //未定義的:fmt.println

原因:

嗯，Go中其實有規定的就是模塊中要導出的函數，必須首字母大寫，所以錯誤的原因就是fmt.Println()寫成了fmt.println()

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

報錯信息:

D:\wamp\www\GoLearn>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編譯器版本不是64位的,訪問https://sourceforge.net/projects/mingw-w64/下載個64位的把環境變量配置好,安裝教程https://www.cnblogs.com/findumars/p/8289669.html
