[vm] compile smart contract pops a panic

use cli to compile a contract:

startcoin% dev compile <wrong path of *.move file>

my cli command as follows(the file actually exists):

dev compile /home/mathxh/Project/starcoin/examples/finger_guess/module/finger_guess.move

and panic pops up,

~~Here is my question: Does the command support absolute paths?~~ I just read related code, it does definitely support absolute path. and it panic in internal of vm module:

pub fn stdlib_files() -> Vec<String> {
    let mut path = PathBuf::from(env!("CARGO_MANIFEST_DIR"));
    path.push(STD_LIB_DIR);
    let dirfiles = datatest_stable::utils::iterate_directory(&path);
    filter_move_files(dirfiles).collect::<Vec<_>>()
}

It just iter STD_LIB_DIR and panic!
