Just do export GOPATH   whatever you like your GOPATH to be

Update  as of Go 1 8  GOPATH defaults to  HOME go  but you may still find this useful if you want to understand the GOPATH layout  customize it  etc    The official Go site discusses GOPATH and how to lay out a workspace directory   export GOPATH   HOME your-workspace-dir   -- run it in your shell  then add it to    bashrc or equivalent so it will be set for you in the future  Go will install packages under src   bin   and pkg   subdirectories there  You ll want to put your own packages somewhere under  GOPATH src  like  GOPATH src github com myusername  if you want to publish to GitHub  You ll also probably want export PATH  PATH  GOPATH bin in your  bashrc so you can run compiled programs under  GOPATH    Optionally  via Rob Pike  you can also set CDPATH so it s faster to cd to package dirs in bash  export CDPATH    GOPATH src github com  GOPATH src golang org x means you can just type cd net html instead of cd  GOPATH src golang org x net html    Keith Rarick notes you can set GOPATH  HOME to put Go s src   pkg  and bin  directories right under your homedir  That can be nice  for instance  you might already have  HOME bin in your path  but of course some folks use multiple workspaces  etc

for MAC   I tried all these answers and  for some still unknown reason  none of them worked   I had to  force feed  the GOPATH by setting the environment variable per every command that required it  For example   sudo env GOPATH  HOME goWorkDirectory go build       Even glide was giving me the GOPATH not set error  Resolved it  again  by  force feeding       I tried all these answers and  for some still unknown reason  none of them worked   I had to  force feed  the GOPATH by setting the environment variable per every command that required it   sudo env GOPATH  HOME goWorkDirectory glide install   Hope this helps someone

For MAC this worked well for me    sudo nano  etc bashrc   and add the below at the end of the file  export PATH  PATH  usr local opt go libexec bin export GOPATH  usr local opt go bin   This should fix the problem  Try opening a new terminal and echo  GOPATH you should see the correct value

This problem occured to me in raspberry pi  I had logged in through VNC client  The problem persisted despite setting and exporting the GOPATH   Then Ran the  go get  command without sudo and it worked perfectly

I am using vim to edit my  bashrc file but you code use a gui editor such as gedit  Steps  Kindly subsitute  path to golang projects below with your actual path location where you will store your golang projects  Open  bashrc file in vim that is vim    bashrc  Then add below lines at the end of the file    Setup Golang Development Environment    export GOROOT  usr local go export PATH  PATH  GOROOT bin     Third party go libraries will live under  quot   golib quot  directory export GOPATH  quot  HOME golib quot  export PATH  quot  PATH  GOPATH bin quot      Where your golang project code lives export GOPATH  GOPATH  path to golang projects  Save the file and type source    bashrc to refresh your terminal session  Now try getting a package e g  go get github com pilu fresh and check your   golib bin directory it should have fresh package in it  Navigate to your  path to golang projects and create three folders in there i e  bin src and pkg Now place your project folder inside  path to golang projects src  e g   path to golang projects src myfancygolangprojectand you should be good to go  Put all your golang codebase in there mate

Watch a Video  In general  I always recommend this official video from Go to get a quick overview on the matter   http   www youtube com watch v XCsL89YtqCs  It s easier to be shown than to be told    jwfearn paraphrased the important part of the video      export GOPATH    HOME  gocode   export PATH    PATH    GOPATH  bin   mkdir -p    GOPATH

I found easier to do it like this   export GOROOT  HOME go export GOPATH  GOROOT bin export PATH  PATH  GOPATH

If you run into this problem after having  GOPATH set up  it may be because you re running it with an unsupported shell  I was using fish and it did not work  launching it with bash worked fine

Run  go env  and see where your GOPATH is currently pointing towards  If you change to that directory  your  go get  etc  command should work

I had to run an application as root  to open a webserver on port 80   this produced the error for me  because the sudo user has a different environment than the normal user  hence GOPATH was not set   If someone else is having this problem  add -E to the command  this will preserve the user environment   sudo -E go run main go  For more infos see discussion here  Google Groups     GOPATH Problem

You can use the  export  solution just like what other guys have suggested  I d like to provide you with another solution for permanent convenience  you can use any path as GOPATH when running Go commands   Firstly  you need to download a small tool named gost   https   github com byte16 gost releases   If you use ubuntu  you can download the linux version https   github com byte16 gost releases download v0 1 0 gost linux amd64 tar gz    Then you need to run the commands below to unpack it      cd  path to your download directory    tar -xvf gost linux amd64 tar gz   You would get an executable gost   You can move it to  usr local bin for convenient use     sudo mv gost  usr local bin   Run the command below to add the path you want to use as GOPATH into the pathspace gost maintains  It is required to give the path a name which you would use later     gost add foo  home foobar bar        foo  is the name and   home foobar bar  is the path   Run any Go command you want in the format    gost goCommand  -p  pathName   --  goFlags      goArgs       For example  you want to run go get github com go-sql-driver mysql with  home foobar bar as the GOPATH  just do it as below     gost get -p foo -- github com go-sql-driver mysql     foo  is the name you give to the path above    It would help you to set the GOPATH and run the command  But remember that you have added the path into gost s pathspace  If you are under any level of subdirectories of  home foobar bar  you can even just run the command below which would do the same thing for short      gost get -- github com go-sql-driver mysql   gost is a Simple Tool of Go which can help you to manage GOPATHs and run Go commands  For more details about how to use it to run other Go commands  you can just run gost help goCmdName  For example you want to know more about install  just type words below in     gost help install   You can also find more details in the README of the project  https   github com byte16 gost blob master README md
