chmod: cannot access '777': No such file or directory

This error message indicates that the `chmod` command cannot find a file or directory named `777` in the current working directory.

The `chmod` command is used to change the permissions of a file or directory. The syntax for using the `chmod` command is:

chmod options permissions file

In the above syntax, `options` are optional and can be used to specify how the permissions should be changed. `permissions` are the new permissions that you want to set for the file or directory, and `file` is the name of the file or directory that you want to change the permissions for.

In your case, it seems like you are trying to set permissions for a file or directory named `777`, which does not exist in the current working directory. Make sure that you have entered the correct file or directory name in the `chmod` command and that it exists in the current working directory.
