Error when trying to build package from github with go-CodePudding

I am trying to install package from github. https://github.com/adnanh/webhook

Version

$ go version
go version go1.17.5 linux/amd64

.profile:

export PATH=$PATH:/usr/local/go/bin

Try:

$ go build github.com/adnanh/webhook
no required module provides package github.com/adnanh/webhook: go.mod file not found 
in current directory or any parent directory; see 'go help modules'

where is a problem?

And I don't have go folder in /root/ with pkg and bin subfolders

CodePudding user response：

Only go install can work outside of any project (without a local .go.mod$

Since Go 1.16, if the arguments have version suffixes (like @latest or @v1.0.0), go install builds packages in module-aware mode, ignoring the go.mod file in the current directory or any parent directory if there is one.

This is useful for installing executables without affecting the dependencies of the main module.

go build is meant to be used within a local project, with its go.mod dependencies list. It compiles, but does not install, a package.
