使用終端命令的 golang-migrate 未知驅動程序 postgresql

Question

當我嘗試使用終端命令（ migrate -path scripts -database "postgresql://postgres:postgres@localhost:5439/basename?sslmode=disable" -verbose down ）向下遷移我的基礎時，出現錯誤： error: database driver: unknown driver postgresql (forgotten import?) 。 如何解決？

Answer 1

我認為您需要使用特定標簽構建以添加特定驅動程序。

請參閱文檔https://github.com/golang-migrate/migrate/tree/master/cmd/migrate#with-go-toolchain

$ go get -u -d github.com/golang-migrate/migrate/cmd/migrate
$ cd $GOPATH/src/github.com/golang-migrate/migrate/cmd/migrate
$ git checkout $TAG  # e.g. v4.1.0
$ go build -tags 'postgres' -ldflags="-X main.Version=$(git describe --tags)" -o $GOPATH/bin/migrate $GOPATH/src/github.com/golang-migrate/migrate/cmd/migrate

Answer 2

go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest
