I am currently trying to learn the basics of Solana Smart Contracts and therefore tried the hello world program. Because I am on Windows, I downloaded Ubuntu on WSL 2. I downloaded Solana-CLI v1.14.18 (also tried with the stable version v1.13.8), had git(v2.34.1) and node (v9.5.0) already installed and created a new directory I just called "Rust". There I cloned the project with git clone ....

I stepped in the directory and am now at jmv@JMV_Legion:~/Rust/example-helloworld. But now trying to run solana-test-validator doesn't work but instead exits with the log (took it from the validator.log):

[2023-05-22T21:29:34.129159283Z INFO  solana_test_validator] solana-validator 1.13.8 (src:43daa379; feat:1775889670)

What do I need to do to solve this? I really would like to start but nothing has worked yet and I really am not experienced in Linux at all.

Thanks!

Reset to default

After re-downloading WSL, Solana, Rust and everything I found out that in WSL/Linux I need to go to the base root to have it executed.

So I hit cd ~ and then solana-test-validatorjust worked. I hope this will help someone who faces the same problems in the future!
