进行安装：在非本地软件包中进行本地导入“ ../app/lib” [重复]

The code works with go build main.go and will run the application. However, go install will throw an error. What gives?

Project structure:

app/
    main.go
    lib/
        StockMarketController.go
        GetStockMarketData.go

In my main.go, the two other .go files are imported as such:

import (
    Lib "../stockmarket-service/lib"
)

And called as such:

Lib.SomeFunction()

And it works!

Why does it fail with go install? How do I fix my import of them?

I'm using IntelliJ IDEA and building it in there with go build, the directory is ~./IdeaProjects/app, could this be the issue?
