I want to install composer for laravel development on my latest version of mac OS. I followed all the step by step instructions to install composer on the website and it installed `composer.phar`. So I have to move to `/usr/local/bin/composer` for it to work. 

I ran the usual command:

```
mv composer.phar /usr/local/bin/composer

```

and it gave an error saying `/usr/local/bin/composer: No such file or directory`

I even added a `sudo` command in front to see if it works and received the same error. I looked up other solution telling me to make a new directory there, but it wouldn't let me do so and gave me a `permission denied` error.
