gleam: No such file or directory src/libcore/result.rs:997:5

Hi Louis,

Trying out Gleam and getting an error when I try to compile an unmodified project built using rebar3 new gleam_lib my_proj

Here is the error:

╰─$ rebar3 compile
===> Plugin {rebar_gleam,{git,"https://github.com/gleam-lang/rebar_gleam"}} not available. It will not be used.

Hi all! I’ve just released a fix for this, as well as Gleam v0.2.0! Please update your copy of the compiler and then update the rebar_gleam plugin with rebar3 as global plugins upgrade rebar_gleam

Thanks for the fix on this Louis and also the library in general, looking forward to playing about with it some more.

@lpil for sure, I can do that 👍 Also I made a make file addition for myself to help make future upgrades easier make upgrade version=0.8.2 . If this is something that’s useful I can add that as well:

.PHONY: upgrade
upgrade:
	git fetch &&\
	git fetch --tags &&\
	git checkout v$(version) &&\
	make install &&\
	rebar3 as global plugins upgrade rebar_gleam

@lpil ah ok thanks for your help! I would have assumed a new project (via rebar_gleam) would have looked for the latest lib before fetching it 🤔

This seems to be a gap in my Erlang tooling knowledge. I’ve only been using Elixir for the beam. I’m assuming adding version numbers to the generated code could be a burden at this early stage but if not it would be helpful for newcomers (or even a comment to add that latest version)

For future readers, I was able to add a version number to my rebar.config, delete the lock file, and recompile to get it to run without issues.

{deps, [
    {gleam_stdlib, "0.3.0"}
]}.
