## The ` go build ` command doesn't do anything! #### The ` go build ` command doesn't do anything!
The ` go build ` command will only produce a binary; if you run go build in a package directory, it will build the package normally (and report any compile errors), but it will not install it. For that, you use ` go install `. If you think you're building a binary and none is produced, make sure you are in package ` main ` and that you do not have GOBIN set.

### Why does ` go get ` work for some packages and report ` permission denied ` in ` $GOROOT ` for some others (with GOPATH set properly)? #### Why does ` go get ` work for some packages and report ` permission denied ` in ` $GOROOT ` for some others (with GOPATH set properly)?
If you at any point installed the package in ` GOROOT ` (either by having no ` GOPATH ` set or by including ` GOROOT ` itself in ` GOPATH `) then there might still be a directory in ` $GOROOT ` (which is always checked first) that is overriding your ` GOPATH `. To verify, run ` go list -f {{.Dir}} importpath ` and if it reports a directory under ` $GOPATH ` try deleting that first.
