No such file or directory (os error 2) nimiq-client

Can you give us more information? What command did you run? Is that the whole output?

I suspect it's because it can't find your configuration file.

yes i was running cargo run command in core rust than to me file not found when i changed toolchain again other error appearing ;) one minute i post

i am trying to build and run on Ubuntu 14.04LTS plus i changed toolchain to nightly

@animanga core-rs targets the nightly toolchain only. Make sure you add a configuration file before running the project: https://github.com/nimiq/core-rs#configuration

[jgraef]

You have to build with nightly. If you use rustup the easiest way is to override the toolchain in the core-rs directory:

rustup override set nightly

Alternatively tell cargo to use nightly:

cargo +nightly run

The issue with No such file or directory is because prior to our commits preparing for a beta release, the client looked for a config.toml in the current directory. But with the recent changes it will create an client.example.toml in $HOME/.nimiq when you first run it. You are then supposed to copy this to client.toml in the same directory and change the config to your needs.

The recent changes also updated the README, so that should be much clearer now. And the error message is much more descriptive now.

EDIT: Also that warning about deserialize_string_vec can be ignored.
