問題點
缺少github.com/boombuler/barcode程序
models/util/code.go:23:2: cannot find package "github.com/boombuler/barcode" in any of: /root/gopath/src/gybadminapi/vendor/github.com/boombuler/barcode (vendor tree) /root/go/src/github.com/boombuler/barcode (from $GOROOT) /root/gopath/src/github.com/boombuler/barcode (from $GOPATH) models/util/code.go:24:2: cannot find package "github.com/boombuler/barcode/qr" in any of: /root/gopath/src/gybadminapi/vendor/github.com/boombuler/barcode/qr (vendor tree) /root/go/src/github.com/boombuler/barcode/qr (from $GOROOT) /root/gopath/src/github.com/boombuler/barcode/qr (from $GOPATH) models/util/code.go:25:2: cannot find package "github.com/golang/freetype" in any of: /root/gopath/src/gybadminapi/vendor/github.com/golang/freetype (vendor tree) /root/go/src/github.com/golang/freetype (from $GOROOT) /root/gopath/src/github.com/golang/freetype (from $GOPATH)
解決辦法 :
在使用go的時候如果依賴導入github上的,比如下面樣式
import "github.com/boombuler/barcode"
在/root/gopath/目錄下執行下載,執行get操作
go get github.com/boombuler/barcode
它會下載到你的gopath目錄下
在我們引入第三方的時候,其會在三個地方區查找
1、GOROOT路徑
2、GOPATH路徑
3、在原目錄中的vendor目錄下進行查找
get執行后,發現src目錄下產生相應的目錄,那么報錯解決
下面安裝go過程可忽略~~~~~~~~~
=============================================================
一、安裝go環境
1.下載go軟件包
官網:https://goproxy.io/zh/
wget https://gomirrors.org/dl/go/go1.15.2.linux-amd64.tar.gz
2.解壓:
tar xf go1.15.2.linux-amd64.tar.gz
3.創建目錄
go安裝目錄:/root/go(無需創建,解壓自得)
go運行目錄:mkdir -p /root/gopath
4.添加環境變量
vim /etc/profile
末尾添加:
export GOROOT=/root/go
export GOPATH=/root/gopath
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
export GOPROXY=https://goproxy.io
最后一行表示,如果在構建中缺少構建文件,將會自動下載
5.立即生效
source /etc/profile
6.查看版本
go version
