export GOPATH=$HOME/IdeaProjects
export GOBIN=$GOPATH/bin
export PATH=$GOBIN:$PATH

GOBIN is the install location of the executable output file after go install.

In Mac OS, you must create a bin file under GOPATH and set the GOBIN variable.
Otherwise, $ go install

go install: no install location for directory /Users/xxx/IdeaProjects/code outside GOPATH
