I get this error while compiling traffico with xmake.

method 'fetch' is not callable (a nil value)

I made a repro xmake.lua for testing

-- xmake.lua
add_rules("mode.debug", "mode.release")
add_requires("elfutils")
target("my_app")
    set_kind("binary")
    set_languages("c99")
    add_files("main.c")
    add_packages("elfutils")

Same result, so it's not related to traffico per se.

This xmake commit should solve the issue. Lemme look into it.

I confirm, that commit solves the issue.

I've tested it with xmake v2.8.1+dev.a7d08d7. To install xmake from a branch containing that commit (eg., dev or master) you can do:

curl -fsSL https://xmake.io/shget.text | bash -s dev
source $HOME/.xmake/profile

Or otherwise, wait for xmake to release v2.8.2 😄
