Hi @nankit0, welcome to the forum!

This issue’s comment might help?

Thanks for your reply @03juan and @outlog but it’s not work for me because i’m facing this error in BlockScout

Hello all
I found the solution of this error
step1 - In our code we have " .tools-versions " files, open it and check elixir,erlang and node’s version
step2 - Install asdf in your system threw github ( " Getting Started | asdf " )
step-3 - Install same version of elixir and erlang using asdf using github or these websites
Elixir { github = GitHub - asdf-vm/asdf-elixir: Elixir plugin for asdf version manager
websites’s link = https://www.pluralsight.com/guides/installing-elixir-erlang-with-asdf ,
website link = Elixir 1.11 and Erlang Docs - Thinking Elixir } ,
Erlang = { github = GitHub - asdf-vm/asdf-erlang: Erlang plugin for asdf version manager }

Hey @nankit0
Were you able to run Blockscout locally in your system?
If yes can you please share the steps you have taken because I’m trying to run it in my system but ending up with these errors

erlang_24.1-1
Elixir 1.12
PostGIS30_12
PostgresSQL 12
nodejs v14.0.0

Hello @mgl_mkc
could you please share your .tools-versions file’s text here ( in this file we have actual version of elixir, erlang and node which we want to require.)

13

try with erlang 23. I couldn’t make rustler work on erlang 24 also @03juan has mentioned that in the thread earler

14

Where is the. Tools versions file
I use blockscout: v3 7.3-beta
Reference link is Installing blockscout under centos7

15

I’ll try Thank you

This is what’s in the tools-versions file

elixir 1.11.4-otp-23

erlang 23.3.4.1

nodejs 14.17.0

18

@mgl_mkc you have 2 options choose any of them
1- you need to install same version which is mentioned in tool-versions file
2- or you can change text in tool-versions file like in your system elixir version is 1.12 and in tool-version file elixir version is 1.14 than change tool-version file text from 1.14 to 1.12. than compile it again.

Ok thank you
