Question

cant import extended library

avonar opened this issue 2 years ago · comments

The following program `sample.go` triggers an unexpected result

package main

import (
	_ "github.com/jackc/pgx/v4/pgxpool"
)

func main() {
	println("Hello, playground")
}

Expected result

$ yaegi run ./main.go
Hello, playground

Got

$ yaegi run ./main.go

Additional Notes

Hello, i tried write plugin for traefik which are using pgx as databse connector.

And got some erros while importing the package.

traefik-w-plugin-example-reverse-proxy-1  | time="2022-09-15T08:17:21Z" level=error msg="Plugins are disabled because an error has occurred." error="gitlab.office.local/avonar/traefik-plugin: failed to import plugin code \"gitlab.office.local/avonar/traefik-plugin\": 1:21: import \"gitlab.office.local/avonar/traefik-plugin\" error: plugins-local/src/gitlab.office.local/avonar/traefik-plugin/demo.go:13:2: import \"github.com/jackc/pgx/v4/pgxpool\" error: unable to find source related to: \"github.com/jackc/pgx/v4/pgxpool\""

I tried research this by simple example with import library in yaegi runtime, and get an error, looks like a bug for me.

also my logs from traefik runtime which are trying to import the same library
