go - go get 的二进制文件在哪里安装？

Question

我想安装 ginkgo 命令，我试过了。

$ go get github.com/onsi/ginkgo/ginkgo
go: downloading golang.org/x/sys v0.0.0-20210616094352-59db8d763f22
go: upgraded github.com/onsi/ginkgo v1.12.1 => v1.16.5

但是我不确定ginkgo命令安装在哪里

这是我的环境。

$ go env
GO111MODULE=""
GOARCH="amd64"
GOBIN=""
GOCACHE="/home/senthilx/.cache/go-build"
GOENV="/home/senthilx/.config/go/env"

GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build1077100959=/tmp/go-build -gno-record-gcc-switches"

该命令没有在我的“GOPATH”中安装ginkgo

$ ls
pkg

$ find . -type f -name ginkgo
$

go get 命令只用于更新模块依赖，它不安装任何二进制文件。安装 main 包的能力是 deprecated in go1.17 .在模块中，go get 命令将显示对依赖项所做的任何更改，正如您在输出中看到的那样:

go: downloading golang.org/x/sys v0.0.0-20210616094352-59db8d763f22
go: upgraded github.com/onsi/ginkgo v1.12.1 => v1.16.5

如果您尝试在模块外使用 go get 它将返回错误:

go: go.mod file not found in current directory or any parent directory.
    'go get' is no longer supported outside a module.
    To build and install a command, use 'go install' with a version,
    like 'go install example.com/cmd@latest'
    For more information, see https://golang.org/doc/go-get-install-deprecation
    or run 'go help get' or 'go help install'.
