How do I SET the GOPATH environment variable on Ubuntu? What file must I edit?

I am trying to do a go get:

go get github.com/go-sql-driver/mysql

and it fails with the following error:

packa

This has been the most annoying thing to deal with. In hopes of saving your time.

IF go was installed as root user. The root user of your system's bash_profile text file ~/.bash_profile needs to have $GOROOT assigned to the go install directory and $GOPATH needs to be assigned to go /src directory.

  ...$# sudo su
  ...$# vi ~/.bash_profile

    ***Story continues in vi editor***

    GOROOT=$GOROOT:/usr/local/go
    GOPATH=$GOPATH:/usr/local/go/src
    ...
    [your regular PATH stuff here]
    ...

be sure the path to go binary is in your path on .bash_profile

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

This PATH can be as long a string it needs to be..to add new items just separate by colon :

exit vi editor and saving bash profile (:wq stands for write and quit)

  [esc] 
  [shift] + [:] 
  :wq

You have to log out of terminal and log back in for profile to initiate again..or you can just kick start it by using export.

...$# export GOPATH=/usr/local/go/src

You can verify go env:

...$# go env

Yay!

GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/usr/local/go/src"
GORACE=""
GOROOT="/usr/local/go"

Now you can sudo and go will be able to download and create directories inside go/src and you can get down to what you were trying to get done.

example

# sudo go get github.com/..

Now you will run into another problem..you might not have git installed..that's another adventure..:)
