This is all bout Unix file permissions. Who and read, write or run a
file.
Permissions are set with the chmod command.

When a file is initially created the permissions look something like
this:

$ ls -l development.log
-rw-r–r-- 1 peterhickman staff 0 26 Feb 09:54 development.log

This means that the user can read and write the file (the ‘rw’ at the
left)
but people in the same group and the user or strangers can only read
it(the
‘r-’ parts). By issuing the following command:

$ chmod 666 development.log

The permissions on the file are changed.

$ ls -l
-rw-rw-rw- 1 peterhickman staff 0 26 Feb 09:54 development.log

Now anyone can read and write to the file.

That is what this error is complaining about. As the file does not have
the
correct permissions it is a good as it not existing.
