一. dlv調試器安裝：
1. Clone the git repository and build:
$ git clone https://github.com/go-delve/delve
$ cd delve
$ go install github.com/go-delve/delve/cmd/dlv
2. Alternatively, on Go version 1.16 or later:
# Install the latest release:
$ go install github.com/go-delve/delve/cmd/dlv@latest
3. Install at tree head:
$ go install github.com/go-delve/delve/cmd/dlv@master
4. Install at a specific version or pseudo-version:
$ go install github.com/go-delve/delve/cmd/dlv@v1.7.0 go.1.11
$ go install github.com/go-delve/delve/cmd/dlv@v1.7.3 go.1.16
$ go install github.com/go-delve/delve/cmd/dlv@v1.7.4-0.20211208103735-2f13672765fe
二. dlv版本和golang版本一致處理
這里要提go mod好處了，go.mod文件管理版本相關，包括依賴包版本
1. 本地環境：
GOPATH: D:\gopath
go version: go version go1.13.3 windows/amd64
2. cd D:\gopath\pkg\mod\github.com\go-delve\delve@v1.7.0
3. cat go.mod, 內容如下：
module github.com/go-delve/delve
go 1.11
require (
github.com/cosiner/argv v0.1.0
github.com/cpuguy83/go-md2man v1.0.10 // indirect
github.com/creack/pty v1.1.9
github.com/google/go-dap v0.5.0
github.com/hashicorp/golang-lru v0.5.4
github.com/inconshreveable/mousetrap v1.0.0 // indirect
github.com/mattn/go-colorable v0.0.0-20170327083344-ded68f7a9561
github.com/mattn/go-isatty v0.0.3
github.com/peterh/liner v0.0.0-20170317030525-88609521dc4b

github.com/spf13/pflag v0.0.0-20170417173400-9e4c21054fa1 // indirect
go.starlark.net v0.0.0-20200821142938-949cc6f4b097
golang.org/x/arch v0.0.0-20190927153633-4e8777c89be4
golang.org/x/sys v0.0.0-20200625212154-ddb9806d33ae
golang.org/x/tools v0.0.0-20191127201027-ecd32218bd7f
gopkg.in/yaml.v2 v2.2.1
)
4. 如上，說明delve@v1.7.0版本至少需要go 1.11版本
