Go：设置GOPATH时，出现$ GOPATH错误

Question

When running the go get command :

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

I get the following error

package github.com/go-sql-driver/mysql: cannot download, $GOPATH not set. For more details see: go help gopath

However $GOPATH is already set.

Running echo $GOPATH gives /Users/userxyz/Desktop/Code

Running go env gives

.....

GOPATH="/Users/userxyz/Desktop/Code"

...

GOROOT="/usr/local/go"

.....

I have already tried setting GOPATH as an environment variable by adding the following lines

export GOPATH="$HOME/Desktop/Code"
export PATH=$PATH:$GOPATH/bin

to the following files, alternatively

~/.profile (/etc/profile)
~/.bashrc
~/.bash_profile

This runs go get under root user, which does not have $GOPATH set.

Just do:

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

go get -t
