刚入门一天的goer安装iris

原来看教程上都是用 go get 获取软件包。提示如下，意思是go get要被废弃了。

我的版本是，go version go1.20.4 windows/amd64

go get -u github.com/kataras/iris
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'.

对这个问题的解释。

Starting in Go 1.17, installing executables with go get is deprecated. go install may be used instead.

Why this is happening

Since modules were introduced, the go get command has been used both to update dependencies in go.mod and to install commands. This combination is frequently confusing and inconvenient: in most cases, developers want to update a dependency or install a command but not both at the same time.

Since Go 1.16, go install can install a command at a version specified on the command line while ignoring the go.mod file in the current directory (if one exists). go install should now be used to install commands in most cases.

go get’s ability to build and install commands is now deprecated, since that functionality is redundant with go install. Removing this functionality will make go get faster, since it won’t compile or link packages by default. go get also won’t report an error when updating a package that can’t be built for the current platform.

See proposal #40276 for the full discussion.

$ go get github.com/kataras/iris/v12@latest 抛弃go get 换 go install 执行。

go install github.com/kataras/iris/v12@latest

go install github.com/kataras/iris@latest
