To solve error like this while trying to upgrade go-qml for go1.3.3
GOPATH/src/gopkg.in/qml.v1/bridge.go:23: import GOPATH/pkg/linux_amd64/gopkg.in/qml.v1/cdata.a: object is [linux amd64 go1.3.1 X:precisestack] expected [linux amd64 go1.3.3 X:precisestack]
I did this
rm -rf $GOPATH/pkg
Then retried upgrading by
go get -u -v gopkg.in/qml.v1/
Now go was able to upgrade the package without any fuss.
Verbose output on the terminal:
