[erlang-questions] Erlang version confusion
Tue Aug 20 23:29:50 CEST 2019
I have Erlang Version 19.0 installed long-ago on my dev system. While testing Nitrogen code my app crashed due to the pesky string library revision problem: string:lexemes/2 was not to be found.
OK, so time to update my working version of Erlang. I have kerl. Piece of cake. This was indeed successful:
Erlang/OTP 22 [erts-10.4] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe]
However, when I try to rebuild my Nitrogen app, it still builds under Erlang Version 19.0.
Here's kerl status:
$ kerl status
No Erlang/OTP installation is currently active
Looks like it might be useful to bring Version 19.0 under kerl. But, problem, I don't know how to decommission the old 19.0 installation.
Can anyone provide the magic incantation?
