I have followed this StackOverflow post to install the specific version of Erlang.
And When I am running
mix ecto.setup then getting following error-
Error loading module telemetry_handler_table: This BEAM file was compiled for a later version of the run-time system than 21. To fix this, please recompile this module with an 21 compiler.
iex command, following version I am getting-
Erlang/OTP 21 [erts-10.3.4] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] Interactive Elixir (1.8.2)
