Golang using SQLITE3 encoding slow problem

This is a created article in which the information may have evolved or changed.

I studied the next xorm today. Build when found particularly slow, build-x-V looked down, time is spent on the compilation github.com/mattn/go-sqlite3

Looked down ${GOPATH}/pkg/darwin_amd64/github.com/mattn unexpectedly did not have. a file. No wonder

Solve

go install github.com/mattn/go-sqlite3

${gopath}/pkg/darwin_amd64/github.com/mattn out of the go-sqlite3.a. Now to build my code, the world is finally quiet again ~ ~
