IntelliJ Golang插件无法导入默认软件包

I just downloaded the latest plugin for Go support in IntelliJ. I'm not able to use intellisense for Go programming because IntelliJ is not able to import packages like fmt and float64.

However, if I run the program from within IntelliJ, it works just fine!

GOROOT is usr/local/go Project GOPATH is /Users/myname/go where the go file is.

What am I missing?

Go to Settings | Languages & Frameworks | Go | GOROOT and make sure your GOROOT is selected there. Then to the same place, but in GOPATH, make sure that's also set correctly.

Also, make sure that you follow the Go Workspace requirements.

I solved this problem by upgrading my IntelliJ IDEA to the latest.
