Setup Golang Workspace (My ZSH Configuration)
Download & Install

Update your shell profile
Go expects the path of the go workspace as the $GOPATH environment variable.
So you need to set up two environments to add the following two lines to your ~/.zshrc or ~/.bashrc or ~/.profile:
export GOPATH=$HOME/Project/Go
Also added the $GOPATH/bin to my system path so that I can use the commands installed from “go install” or “go get”.
export PATH=$GOPATH/bin:$PATH
You can set the environment variable GOPATH to any directory you like. If you have larger projects, it's probably a good idea to create a different GOPATH for each of them. I would recommend this approach especially for the deployment, so that updating a library for project A doesn't break project B which might require an earlier version of the very same library.
And do not forget to reload your change .zshrc afterward
$ source ~/.zshrc
Then create your the workspace directories:
$ mkdir -p $GOPATH $GOPATH/{src,pkg,bin}
Test your environment
$ go env
For example, I created a directory named “github.com” under “src” and then created “whitehorse0” under that.
Now my projects would reside in: ~/Project/Go/src/github.com/whitehorse0 directory.
I can now treat ~/Project/Go/src/github.com/whitehorse0 directory as my personal workspace.
So, I added these to my .zshrc for convenience:
export GOWORKSPACE=$GOPATH/src/github.com/whitehorse0
Once I got this done, I can actually do this when creating a new project:
$ cd $GOWORKSPACE
$ take my_first_project
$ go mod init my_first_project
