Error when attempting to verify smart contract about blockscout-terraform HOT 7 CLOSED

Is Node being used for something post-build? If that's the case, then yes, installing Node globally is the best approach. The reason why Node is not installed currently, is because it was (previously) only required during builds to generate front-end assets, so by the time the application was installed on the EC2 host, Node was no longer needed. If that's changed, the init.sh script will need to install Node along with the other packages it installs.

:enoent is the Erlang form of ENOENT from Posix, so it means that the compile_solc.js isn't installed. Did you run the steps in the README to install the JS code for `apps/explorer?

Yes, everything was run and it was working locally before the upload to AWS. Does :enoent need to be installed during the infra build?

from blockscout-terraform.

ENOENT (and the error tuple form in Erlang/Elixir :enoent) is just an error code which says that a given file descriptor doesn't exist (it would be translated something like "Error: no such file system entry"). For whatever reason, the that file can't be found on the host, so it either isn't being bundled into the source files uploaded to CodeDeploy, or is being removed somehow - I would suspect the former though.

Is there a chance that this is happening due to missing user permissions?

This file /opt/app/_build/prod/lib/explorer/priv/compile_solc.js exists so I'm having issues solving this issue still. I'll keep digging.

command is expected to be an executable available in PATH unless an absolute path is given.

The problem is that the System.cmd is not finding the node command:

[ec2-user@ip-10-0-0-245 explorer]$ node --v
-bash: node: command not found

[ec2-user@ip-10-0-0-245 explorer]$ iex -S mix
Erlang/OTP 20 [erts-9.3] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false]

Interactive Elixir (1.6.4) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> System.find_executable("node")
nil

There are two ways of fixing this:

1. Install the node globally in the machine;
2. Distribute it in priv and keep the executables in the project repository.

I'm thinking about going with the first option to solve this one, but I'm not sure how we will handle this dependency for the next deploys, maybe add some condition to the bin/deploy file as well.

WDYT @bitwalker ?
