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 page explains how to set this variable on various platforms. Setting go environment variables for executing "go mod tidy" go env -w GOPROXY=direct go env -w GOSUMDB=off

  • Bash
  • Zsh
  • fish
• Windows

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

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

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

export GOPATH=$HOME/go

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

source ~/.zshrc

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.

Your workspace can be located wherever you like, but we'll use C:\go-work in this example.

NOTE: GOPATH must not be the same path as your Go installation.

• Create folder at C:\go-work.
• Right click on "Start" and click on "Control Panel". Select "System and Security", then click on "System".
• From the menu on the left, select the "Advanced systems settings".
• Click the "Environment Variables" button at the bottom.
• Click "New" from the "User variables" section.
• Type GOPATH into the "Variable name" field.
• Type C:\go-work into the "Variable value" field.
• Click OK.

There is a faster way to edit Environment Variables via search:

• Left click on "Search" and type env or environment.
• Select "Edit environment variables for your account".
• ... and follow steps above.

• Open a command prompt (windows-key + r then type "cmd") or a powershell window (windows-key + i)
• Type setx GOPATH %USERPROFILE%\go (this will set the GOPATH to your [home folder]\go e.g. C:\Users\yourusername\go
• Close the command or powershell window (the environment variable is only available for new command or powershell windows, not for the current window).
