Plugin pc not available

Question

When I try to build my app at server as:

APP="my_app" MIX_ENV="prod" AUTO_VERSION="" BRANCH="master" SKIP_RELUP_MODIFICATIONS="" RELUP_MODIFICATION_MODULE="" USING_DISTILLERY="true" mix do clean, compile

I get this error:

===> Plugin pc not available. It will not be used.

$ ~/.mix/rebar3 -v

Any idea?

Answer 1

The error message mandatory chunk of type 'Atom' not found suggests that you have a .beam file compiled with Erlang/OTP 20.0 or later, and are trying to load it in an earlier version. Try deleting the .beam files for the pc plugin and let it rebuild them.
