What was wrong?

Interface build get_path is incorrect

File "brownie/_cli/main.py", line 58, in main
importlib.import_module(f"brownie._cli.{cmd}").main()
File "brownie/_cli/compile.py", line 32, in main
project.load(project_path)

--> :8:1:

8 | import "./IERC20.sol";
| ^^^^^^^^^^^^^^^^^^^^^^

Error: Source "IERC777.sol" not found: File not found.
--> :9:1:
|
9 | import "./IERC777.sol";

How can it be fixed?

import "../interfaces/IERC20.sol";

even though the interface referenced is in the same directory.
