Seems to be fixed in pc v1.15 by #80

[slashmili]

I see, the question comes to my mind is why rebar is fetching v1.14.0 ? Is there another configuration/version update needs to be done for rebar to get v1.15.0?

This is the rebar I'm using

rebar3 version
rebar 3.23.0 on Erlang/OTP 27 Erts 15.0

[badlop]

why rebar is fetching v1.14.0 ?

Maybe:

1. your rebar3 fetched pc some weeks ago, when the latest one was 1.14.
2. right now, you tell rebar3 to install pc without specifying which version you want
3. rebar3 first looks in $HOME/.cache/rebar3/hex/hexpm/packages and finds that there's pc 1.14 already downloaded, and uses that one... why not?

If that's your case, some ideas:

• Run: rebar3 plugins upgrade --all
• or specify {plugins, [{pc, "1.15.0"}]}.

[slashmili]

This is my cache dir

$ ls -rf -l $HOME/.cache/rebar3/hex/hexpm/
total 0
drwxr-xr-x  2 milad  staff   64 25 Jun 14:50 ./
drwxr-xr-x  4 milad  staff  128 13 Jun 10:42 ../

seems like that upgrade command did the trick.

$ rebar3 plugins upgrade --all

The issue is that I'm using snappyer and in that package, the pc version is not pinned in the plugins settings.

Thanks for the hint!
