go build get 問題處理

 
client.go:9:2: cannot find module providing package google.golang.org/grpc: working directory is not part of a module
 
因為開啟mod模式了

export GO111MODULE=auto

 
另外一種方法就是使用mod模式

export GO111MODULE=on
go mod init
go mod vendor
#缺少什么包，go get什么包

--------------------------
[root@centos7 multissh-master]# echo $GOPATH
/root/go
[root@centos7 multissh-master]# echo $GOROOT
/usr/local/go
[root@centos7 multissh-master]# which go
/usr/local/go/bin/go
[root@centos7 multissh-master]#


--------------------------
[root@centos7 multissh-master]#  go get github.com/go-sql-driver/mysql
go: finding github.com/go-sql-driver/mysql v1.5.0
go: downloading github.com/go-sql-driver/mysql v1.5.0
go: extracting github.com/go-sql-driver/mysql v1.5.0
[root@centos7 multissh-master]#  

4. 在代碼中導入下載的那個第三方包
import (
    "github.com/go-sql-driver/mysql" // 從環境變量：%goPath% 中定義的路徑去查找第三方類庫
)

[root@centos7 multissh-master]# go get github.com/shanghai-edu/multissh
go: finding github.com/shanghai-edu/multissh latest
go: finding golang.org/x/crypto latest


[root@centos7 multissh-master]# go get github.com/shanghai-edu/multissh/funcs
go: finding github.com/shanghai-edu/multissh latest
go get github.com/shanghai-edu/multissh/funcs: no matching versions for query "upgrade"

[root@centos7 multissh-master]# go get -u -v github.com/shanghai-edu/multissh/funcs

--------------------
而要讓檔案自動儲存到指令的目錄下，則需要借用-P這個參數，可以使用以下的指令
wget -P 目錄 網址
舉例來說，如果你要放到/root底下，你可以打下列的指令：
wget -P /root 網址

golang unrecognized import path "golang.org/x/crypto"的解決方法

用代理還是靠譜些

    [root@test rttys]# export GOPROXY=https://goproxy.io
    [root@test rttys]# export GO111MODULE=on
    [root@test rttys]# go get


------------------
go cannot find package "golang.org/x/crypto/ssh/terminal" 解決方案


    進入$GOPATH(你的安裝go 的路徑)
    進入 $GOPATH/src, 創建文件夾 golang.org， 以及子文件夾 golang.org/x
    進$GOPATH/golang.org/x 使用如下命令：
    clone crypto 以及 sys 即可

git clone https://github.com/golang/crypto.git
 
$ git clone https://github.com/golang/crypto.git
