GOPATH is empty

[JeepLin]

after install idea, i import and try to run my project and found out the error says : src/warehouse/main.go:55:2: cannot find package "glog" in any of: /usr/local/go/src/glog (from $GOROOT) ($GOPATH not set)

then i open the terminal in idea and found that GOPATH is null

but in the shell GOPATH is not null

so i was confused....help....

Depending on which shell you are using and where you've put the configuration for GOPATH it won't be picked up by default.
When you open a Go file the IDE should prompt you to select one. You can still chose the GOPATH by going to FIle | Settings | Languages & Frameworks | Go | Go Libraries and there you can either configure a Global one which will apply to all projects or a Project one which will apply only to the current project.
If you have any problems in figuring it out, please let me know and I'll try my best to get this sorted out.
