Go Get Not Downloading to SRC Folder

Question

Expected: I install the package using go get, and it creates all necessary folders in the src folder, but they only appear in the pkg/mod folder and I can’t use them.

Reality: it says it’s downloading, finishes, then nothing.

Everything is setup correctly in Windows Env Variables, this just.. doesn’t work.

Command Used: go get github.com/fatih/color

Go Env:

Answer 1

Setting up GO111MODULE env variable to off solved it for me. I'm using zsh. Here's the command I have put in my .zshrc file,

export GO111MODULE=off

My working environment: macOS Big Sur, Go version: 1.16

Go modules will hold the dependencies in $GOPATH/mod.

As such, when you'll import them into your project, you need to worry about two things: they are imported in a .go file and they are present in the go.mod file.

Once downloaded for a certain version, they will be available for all future projects.

If you want learn more about them and how they are organized, you can read the Go Modules Wiki available here https://github.com/golang/go/wiki/Modules

Since Go 1.15, go get by default will download source codes inside $GOPATH/pkg/mod/ (GOMODCACHE) which is in place of what it used to be $GOPATH/src/. (Ref: https://go.dev/doc/go1.15#go-command)

Turning off Go modules like GO111MODULE=off to download sources is a bad idea.

If you just need to download the sources, I strongly recommend you to use git clone instead.

$ git clone https://github.com/fatih/color

If you need to have it in $GOPATH/src/, just run:

$ git clone https://github.com/fatih/color $GOPATH/src/github.com/fatih/color

Please note that as of Go 1.14, Go projects are no longer confined to $GOPATH/src/ with support of Go modules. You don't really need that folder now. The $GOPATH/src/ folder was for dependency management before even Go modules were introduced.

Users are now advised to move to Go modules as https://github.com/golang/go/wiki/Modules states: "Since Go 1.14, module support is considered ready for production use, and all users are encouraged to migrate to modules from other dependency management systems".

You can try this command.

export GO111MODULE=off
go get github.com/fatih/color
