Command not found go — on Mac after installing Go

Like bjhaid mentioned in the comments above:

This is happening because you must add your PATH to your ~/.zshrc file.

in the ~/.zshrc you should add the line:

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

you should then source you .zshrc file:

. ~/.zshrc

For bash, you should edit the .bashrc file and add the abobe mentioned line:

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

Add the following line to ~/.bashrc or ~/.bash_profile file at the end on your Mac

alias go="/usr/local/go/bin/go"

And in the Terminal

source ~/.bashrc or source ~/.bash_profile in an existing terminal session. Or to see the new changes you can also re-open a new terminal session.

This is what i did on my mac:

opened the file ~/.zshrc using sudo nano ~/.zshrc then pasted

export PATH=$PATH:/usr/local/go/bin save and exit(ctrl + s, ctrl + x then press y) then ran

. ~/.zshrc go was up and running, verified by typing just go in command line.

I kept running into issues and followed the steps on here and finally got a working solution: http://totzyuta.github.io/blog/2015/06/21/installing-go-by-homebrew-on-mac-os-x/

Install w/brew:

brew install golang

Edit bash_profile and add following paths:

nano ~/.bash_profile


export GOROOT=/usr/local/opt/go/libexec
export GOPATH=$HOME/.go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

Source it:

source ~/.bash_profile

Then restart terminal

go version

Output: go version go1.12 darwin/amd64

In my case I was not having ~/.zshrc profile file. Followed below steps to make it work.

Mac os version : Mojave (10.14.6)

Go version : go1.13.1 darwin/amd64

As mentioned in link, when i was executing "go env" command, it was throwing error "go command not found". Adding "export PATH=$PATH:/usr/local/go/bin" in "~/.bashrc" profile file didn't do any magic!!

step 1 : Create .zshrc profile under home path.

$ cd /User/xxxx (Eg : /User/tapan)

$ touch .zshrc

step 2 : append 'PATH' with go in .zshrc file.

$ vim .zshrc

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

step 3 : source your .zshrc file

$ source ~/.zshrc

step 4 : execute "go env" command, you should be able to see local environment details.

$ go env

Add Go PATH to your ~/.zshrc file. Open file to edit as -

vim ~/.zshrc

in the ~/.zshrc you should add the line:

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

Once done, close and reopen terminal and you are good to go. For test, you can do -

go version

It will show output something like -

go version go1.15.1 darwin/amd64

The GOPATH environment variable specifies the location of your workspace. If no GOPATH is set, it is assumed to be $HOME/go on Unix systems and %USERPROFILE%\go on Windows. If you want to use a custom location as your workspace, you can set the GOPATH environment variable.

This answer explains how to set this variable on various Unix systems.

GOPATH can be any directory on your system. In Unix examples, we will set it to $HOME/go (the default since Go 1.8). Note that GOPATH must not be on the same path as your Go installation. Another common setup is to set GOPATH=$HOME.

Go 1.13+

go env -w GOPATH=$HOME/go

Bash

Edit your ~/.bash_profile to add the following line:

export GOPATH=$HOME/go

Save and exit your editor. Then, source your ~/.bash_profile.

source ~/.bash_profile

Zsh

Edit your ~/.zshrc file to add the following line:

export GOPATH=$HOME/go

Save and exit your editor. Then, source your ~/.zshrc.

source ~/.zshrc

fish

set -x -U GOPATH $HOME/go

The -x is used to specify that this variable should be exported and the -U makes this a universal variable, available to all sessions and persistent.
