vs code golang开发 代理设置, 告别手动下载工具包

之前在家里的电脑上是整理过一遍了, 遗憾的是没有记录, 最近想把公司的win电脑也搭下环境, 没想到又是从头到尾摸索了一遍, 索性记录下, 供以后参考吧.

1. GO环境安装

2. VScode环境搭建

2.1 vscode插件安装

2.2 vscode go tools安装

为了使用起来更顺手, 需要下载一部分工具, 但是联网直接安装是要从Google网站下载数据的, 因为众所周知的原因, 不能科学上网的小伙伴们只能得到一连串的安装失败提示, 但好在这些数据在GitHub是有托管的, 只能麻烦点手动安装了.

一般在开始编辑GO文件时, vscode会自动提示安装插件, 如果没有, 也可以手动触发:

win下使用Ctrl+Shift+P组合键召唤出命令控制台:

然后输入Go:Install/Update Tools,并回车:

首先选择左上角的复选框, 选中所有工具, 然后点击右上角的OK.

但选了安装之后, 不能科学上网的童鞋只能在控制台OUTPUT里收到下面这一堆错误提示:

我们接下来要做的就是修复这一堆错误.

---------------划重点----------------------

中国人苦go代理久矣, 哪里有压迫哪里就有反抗, 活人总不能被尿憋死, 早就有前辈们帮忙解决好这个问题了, 轻轻松松改下go的代理就好了:

Go 1.13 及以上（推荐）

打开你的终端并执行

$ go env -w GO111MODULE=on
$ go env -w GOPROXY=https://goproxy.cn,direct
完成。

macOS 或 Linux

打开你的终端并执行

$ export GO111MODULE=on
$ export GOPROXY=https://goproxy.cn
或者

$ echo "export GO111MODULE=on" >> ~/.profile
$ echo "export GOPROXY=https://goproxy.cn" >> ~/.profile
$ source ~/.profile
完成。

好了, 如果你设置完了, 剩下的就都不用看了, 直接开始使用就好了!!!

---------------划重点----------------------

首先我们进入到%GOPATH%\src路径, GOPATH可以通过以下方法拿到:

方法1: win桌面右键选择我的电脑->属性->高级系统设置->高级->环境变量(N)...:

方法2:

使用win+R组合键, 输入CMD打开命令行, 输入go env就可以看到一系列配置项, 里面的GOPATH就是我们要找的路径:

接下来在%GOPATH%/src下面建立两个文件夹路径:

src
|__golang.org
|   |__x
|__github.com

然后我们把需要的包拉下来.

首先再开个CMD窗口, 进入%GOPATH%\src, 用go get获取工具包:

go get -u -v github.com/ramya-rao-a/go-outline
go get -u -v github.com/acroca/go-symbols
go get -u -v github.com/mdempsky/gocode
go get -u -v github.com/rogpeppe/godef
go get -u -v golang.org/x/tools/cmd/godoc
go get -u -v github.com/zmb3/gogetdoc
go get -u -v github.com/golang/lint/golint
go get -u -v github.com/fatih/gomodifytags
go get -u -v golang.org/x/tools/cmd/gorename
go get -u -v sourcegraph.com/sqs/goreturns
go get -u -v golang.org/x/tools/cmd/goimports
go get -u -v github.com/cweill/gotests/...
go get -u -v golang.org/x/tools/cmd/guru
go get -u -v github.com/josharian/impl
go get -u -v github.com/haya14busa/goplay/cmd/goplay
go get -u -v github.com/uudashr/gopkgs/cmd/gopkgs
go get -u -v github.com/davidrjenni/reftools/cmd/fillstruct
go get -u -v github.com/alecthomas/gometalinter

上面这些命令, 有一部分可能会执行失败, 遇到的话可以尝试直接通过git把仓库克隆下来.

举个例子,

如果go get -u -v golang.org/x/tools/cmd/godoc执行失败, 可以使用下面的命令克隆:

git clone [email protected]:golang/tools.git

但是注意clone到的仓库要放到对应的目录下.

全部下载到后就可以通过go install安装了, 举个例子:

go install golang.org/x/tools/cmd/guru

这个包依赖较多, 可能会碰到类似下面的错误提示:

golang.org\x\tools\internal\imports\mod.go:17:2: cannot find package "golang.org/x/mod/module" in any of:
        E:\Go\src\golang.org\x\mod\module (from $GOROOT)
        F:\go\src\golang.org\x\mod\module (from $GOPATH)
golang.org\x\tools\internal\gocommand\vendor.go:16:2: cannot find package "golang.org/x/mod/semver" in any of:
        E:\Go\src\golang.org\x\mod\semver (from $GOROOT)

        E:\Go\src\golang.org\x\xerrors (from $GOROOT)
        F:\go\src\golang.org\x\xerrors (from $GOPATH)

根据提示把这3个依赖包安装上就好了, 也是通过go get放到错误提示里的对应目录里面去, 然后再执行go install.

of:
E:\Go\src\golang.org\x\xerrors (from $GOROOT)
F:\go\src\golang.org\x\xerrors (from $GOPATH)

根据提示把这3个依赖包安装上就好了, 也是通过```go get```放到错误提示里的对应目录里面去, 然后再执行```go install```.
