1、开启Go Module
1、修改环境变量
C:\Users\Administratorgo env -w GO111MODULEonC:\Users\Administratorgo env -w GOPROXYhttps://goproxy.cn,direct#GO111MODULE 三种值
GO111MODULEoff go命令行将不会支持module功能寻找依赖包的方式将会沿用旧版本那种
通过vendor目录或GOPATH模式来查找
GO111MODULEon go命令将会使用module也不会取GOPATH目录下查找
GO111MODULEauto 默认值go命令将会根据当前目录来决定是否启用module功能2、命令行方式创建Go Module项目
mkdir projectname
cd projectname
go mod init projectname

D:\GO_workspace_web\test_modelgo mod help #查看帮助
Go mod provides access to operations on modules.Note that support for modules is built into all the go commands,
not just go mod. For example, day-to-day adding, removing, upgrading,
and downgrading of dependencies should be done using go get.
See go help modules for an overview of module functionality.Usage:go mod command [arguments]The commands are:download download modules to local cacheedit edit go.mod from tools or scriptsgraph print module requirement graphinit initialize new module in current directorytidy add missing and remove unused modulesvendor make vendored copy of dependenciesverify verify dependencies have expected contentwhy explain why packages or modules are neededUse go help mod command for more information about a command.
初始化一个module模块名为项目名
go mod init projectname
下载module到本地cache路径为go env中的GOMODCACHE
go mod download
通过工具或脚本剪辑go.mod文件选项有-json、-require和-exclude可以使用帮助go help mod edit
D:\GO_workspace_web\test_modelgo help mod edit
usage: go mod edit [editing flags] [-fmt|-print|-json] [go.mod]Edit provides a command-line interface for editing go.mod,
for use primarily by tools or scripts. It reads only go.mod;
it does not look up information about the modules involved.
By default, edit reads and writes the go.mod file of the main module,
but a different target file can be specified after the editing flags.The editing flags specify a sequence of editing operations.The -fmt flag reformats the go.mod file without making other changes.
This reformatting is also implied by any other modifications that use or
rewrite the go.mod file. The only time this flag is needed is if no other
flags are specified, as in go mod edit -fmt.The -module flag changes the modules path (the go.mod files module line).The -requirepathversion and -droprequirepath flags
add and drop a requirement on the given module path and version.
Note that -require overrides any existing requirements on path.
These flags are mainly for tools that understand the module graph.
Users should prefer go get pathversion or go get pathnone,
which make other go.mod adjustments as needed to satisfy
constraints imposed by other modules.The -excludepathversion and -dropexcludepathversion flags
add and drop an exclusion for the given module path and version.
Note that -excludepathversion is a no-op if that exclusion already exists.The -replaceold[v]new[v] flag adds a replacement of the given
module path and version pair. If the v in oldv is omitted, a
replacement without a version on the left side is added, which applies
to all versions of the old module path. If the v in newv is omitted,
the new path should be a local module root directory, not a module
path. Note that -replace overrides any redundant replacements for old[v],
so omitting v will drop existing replacements for specific versions.

添加缺失或者删除没有使用的modules
go mod tidy
在本地生成vendor目录(旧方式)
go mod vendor
验证依赖是否正确

3、使用GoLand创建Go Module项目
1、File---New---Project....
有Go modules就选择没有就选择Go 点击Create创建会自动创建go.mod文件如下图 其他操作和上面命令行那种方式一样的操作即可。
4、GoLand配置File Watchers
File---Settings--Tools---File Watchers,选择按照如下配置go fmt和goimports Golang学习深入(一)
干我们这行啥时候懈怠就意味着长进的停止长进的停止就意味着被淘汰只能往前冲直到凤凰涅槃的一天
