can't load package: package .: no buildable Go source files

Here is the error message:

% go get     
can't load package: package .: no buildable Go source files in /Users/7yan00

% echo $GOPATH     
/Users/7yan00/Golang

How would you troubleshoot that error?

Make sure you are using that command in the Go project source folder (like /Users/7yan00/Golang/src/myProject).

One alternative (similar to this bug) is to use the -d option (see go get command)

go get -d

The -d flag instructs get to stop after downloading the packages; that is, it instructs get not to install the packages.

See if that helps in your case.

But more generally, as described in this thread:

go get is for package(s), not for repositories.

so if you want a specific package, say, go.text/encoding, then use

go get code.google.com/p/go.text/encoding

if you want all packages in that repository, use ... to signify that:

go get code.google.com/p/go.text/...

You should check the $GOPATH directory. If there is an empty directory of the package name, go get doesn't download the package from the repository.

For example, If I want to get the github.com/googollee/go-socket.io package from it's github repository, and there is already an empty directory github.com/googollee/go-socket.io in the $GOPATH, go get doesn't download the package and then complains that there is no buildable Go source file in the directory. Delete any empty directory first of all.
