What is the best practice to install packages (those with go get...) in a local directory?
Example: I'd like to try out the Revel web framework, but I don't want to clutter my go installation at /usr/local/go.
Normally I'd say sudo go get github.com/robfig/revel as written on the home page, but that would install it beneath /usr/local/go/src/pkg/....
Is there an easy way to say (for example) go get --local ... and have the package in the current (sub) directory?
You can export the env variable GOPATH. For me it is ~/local/lib/go. This folder has the subfolders bin, pkg and src, so it's just like /usr/local/go. The go-tool will then automatically download , build and install packages into this directory.
