Error just after installation.

[phozzy]

Hello!
I've an error just after installation of rust language and rustling. I used this https://rustup.rs/ to install rust, and following commands to install rustling:

cd ~
curl -L https://git.io/rustlings | bash
cd rustlings

after I run rustlings verify I got this error:

$ rustlings verify
⚠️   Compilation of exercises/variables/variables1.rs failed! Compiler error message:

error: aborting due to 2 previous errors

For more information about this error, try `rustc --explain E0425`.
```
Am I doing something wrong?

It's supposed to error! The errors tell you what's broken about the exercise code so that you can fix it. See here: https://github.com/rust-lang/rustlings#doing-exercises
