golang之vscode环境配置

go语言开发，选择vscode作为IDE工具也是一个不错的选择，毕竟goland收费，老是破解也挺麻烦，除了这点，不过说实话挺好用的。vscode的话相对来说就毕竟原始，适合初学者。

1、vscode首先需要安装go语言插件，在vscode扩展中搜索“go”，如下图，下载安装go插件

2、vscode环境配置

打开vscode设置，菜单File -> Preferences -> Settings，Extensions=>Go configuration找到GoPath设置项，选择Edit in setting.json

设置GoPath（go工作路径）和GoRoot（go安装包路径）路径，如下图

3、vscode会自动弹框提示安装其他插件(编写go代码时)，如下图，选择InstallAll

不过由于网络限制问，基本是安装不成功

解决办法一：手动下载安装

以github.com开头的，如下这些，在src目录下创建一个目录，命名为github

Installing github.com/mdempsky/gocode FAILED
Installing github.com/uudashr/gopkgs/cmd/gopkgs FAILED
Installing github.com/ramya-rao-a/go-outline FAILED
Installing github.com/acroca/go-symbols FAILED
Installing github.com/cweill/gotests/... FAILED
Installing github.com/fatih/gomodifytags FAILED
Installing github.com/josharian/impl FAILED
Installing github.com/davidrjenni/reftools/cmd/fillstruct FAILED
Installing github.com/haya14busa/goplay/cmd/goplay FAILED
Installing github.com/godoctor/godoctor FAILED
Installing github.com/go-delve/delve/cmd/dlv FAILED
Installing github.com/stamblerre/gocode FAILED
Installing github.com/rogpeppe/godef FAILED
Installing github.com/sqs/goreturns FAILED

在src/github目录下，git clone下载这安装失败的插件

git clone https://github.com/mdempsky/gocode
git clone https://github.com/uudashr/gopkgs
git clone https://github.com/ramya-rao-a/go-outline
git clone https://github.com/acroca/go-symbols
git clone https://github.com/cweill/gotests
git clone https://github.com/fatih/gomodifytags
git clone https://github.com/josharian/impl
git clone https://github.com/davidrjenni/reftools
git clone https://github.com/haya14busa/goplay
git clone https://github.com/godoctor/godoctor
git clone https://github.com/go-delve/delve
git clone https://github.com/stamblerre/gocode
git clone https://github.com/rogpeppe/godef
git clone https://github.com/sqs/goreturns

下载成功后，再在src目录下新建一个github.com目录，把上面下载的插件安按照按照失败提示信息放到相应目录下，注意路径一定要和前面提示的路径一致，如下图

然后在src目录下执行go install命令生成可执行文件

go install github.com/mdempsky/gocode
go install github.com/uudashr/gopkgs/cmd/gopkgs
go install github.com/ramya-rao-a/go-outline
go install github.com/acroca/go-symbols
go install github.com/cweill/gotests/...
go install github.com/fatih/gomodifytags
go install github.com/josharian/impl
go install github.com/davidrjenni/reftools/cmd/fillstruct
go install github.com/haya14busa/goplay/cmd/goplay
go install github.com/godoctor/godoctor
go install github.com/go-delve/delve/cmd/dlv
go install github.com/stamblerre/gocode
go install github.com/rogpeppe/godef
go install github.com/sqs/goreturns

生成的可执行文件如下：

对应golang.org/x/开的插件，在src目录下新建目录golang.org\x，然后去github go官方地址https://github.com/golang，找到对应插件库下载下来即可，目前暂时要用到的只有tools和lint库，地址如下，以后开发中遇到“golang.org/x”库缺少的情况，都可以这样解决

git clone https://github.com/golang/tools.git
git clone https://github.com/golang/lint.git

下载下来后如下,

在src目录下执行如下命令：

go install golang.org/x/tools/cmd/guru
go install golang.org/x/tools/cmd/gorename
go install golang.org/x/lint/golint

会在go工作目录bin下生成相应的可执行文件，如下图

这个办法比较繁琐

另外一个解决办法，是使用gopm包管理工具安装

安装gopm:

go get -u github.com/gpmgo/gopm

试着使用gopm get命令拉去，报错如下：

有经验的话，很明显就可以判断是gopm可执行文件路径未加入到系统环境变量path中

gopm命令默认存放在GOPATH（go工作环境）下的bin文件下，把这个路径加入到系统环境变量path中即可，

需要重新启一下终端(cmd或者vscode)，然后在src目录下使用gopm get -l 拉取依赖包到当前目录，执行如下命令：

gopm get -l github.com/mdempsky/gocode
gopm get -l github.com/uudashr/gopkgs/cmd/gopkgs
gopm get -l github.com/ramya-rao-a/go-outline
gopm get -l github.com/acroca/go-symbols
gopm get -l github.com/cweill/gotests/...
gopm get -l github.com/fatih/gomodifytags
gopm get -l github.com/josharian/impl
gopm get -l github.com/davidrjenni/reftools/cmd/fillstruct
gopm get -l github.com/haya14busa/goplay/cmd/goplay
gopm get -l github.com/godoctor/godoctor
gopm get -l github.com/go-delve/delve/cmd/dlv
gopm get -l github.com/stamblerre/gocode
gopm get -l github.com/rogpeppe/godef
gopm get -l github.com/sqs/goreturns
gopm get -l golang.org/x/tools/cmd/guru
gopm get -l golang.org/x/tools/cmd/gorename
gopm get -l golang.org/x/lint/golint

下载完成后，看了下src/bin目录下没有生产可执行文件，手动go install 一下

go install github.com/mdempsky/gocode
go install github.com/uudashr/gopkgs/cmd/gopkgs
go install github.com/ramya-rao-a/go-outline
go install github.com/acroca/go-symbols
go install github.com/fatih/gomodifytags
go install github.com/josharian/impl
go install github.com/davidrjenni/reftools/cmd/fillstruct
go install github.com/haya14busa/goplay/cmd/goplay
go install github.com/godoctor/godoctor
go install github.com/go-delve/delve/cmd/dlv
go install github.com/stamblerre/gocode
go install github.com/rogpeppe/godef
go install github.com/sqs/goreturns
go install golang.org/x/tools/cmd/guru
go install golang.org/x/tools/cmd/gorename
go install golang.org/x/lint/golint

至此vscode golang环境安装好了

把我按在好的包放在github上了，地址：https://github.com/marshhu/golang-package  需要的可以直接下载下来
