can't use go module in go 1.14

[gclove]

import elasticsearch7 "github.com/elastic/go-elasticsearch/v7"

But in the latest version of gomacro is successful.

gomacro> import elasticsearch7 "github.com/elastic/go-elasticsearch/v7"
// debug: looking for package "github.com/elastic/go-elasticsearch/v7" ...
// debug: compiling "/Users/gclove/go/src/gomacro.imports/github.com/elastic/go-elasticsearch/v7/v7.go" ...
go: finding module for package github.com/elastic/go-elasticsearch/v7
go: found github.com/elastic/go-elasticsearch/v7 in github.com/elastic/go-elasticsearch/v7 v7.8.0

Can you please copy the output of go env ? Thanks

[encryptblockr]

how are you using go 1.14? can you please share?
also how do you install go packages?

i am not able to install go packages

exec into the docker container

# docker exec -it gophernotes sh

then tried to install packages with go get -v gorm.io/driver/postgres

/ # go get -v gorm.io/driver/postgres

is this right way to install packages by doing it inside the container? will appreciate any help
thanks
