Brownie init doesn't work when you specify a path with unmade parent folder

[cjidboon94]

Environment information

• brownie Version: 1.14.6
• ganache-cli Version: 6.12.2 (irrelevant tho)
• solc Version: 0.7.3 (irrelevant)
• Python Version: 3.9.5
• OS: osx/win (and probably linux, not tested)

What was wrong?

Please include information like: When running brownie init ~/parent-folder-doesn't-exist/child, brownie init will fail because of the default behaviour of Path.mkdir. (e.g. see this stackoverflow question)

C:\WINDOWS\system32>brownie init C:\Users\Chris\Documents\Brownie
INFO: Could not find files for the given pattern(s).

  File "c:\users\chris\appdata\local\programs\python\python39\lib\site-packages\brownie\_cli\__main__.py", line 64, in main

  File "c:\users\chris\appdata\local\programs\python\python39\lib\site-packages\brownie\project\main.py", line 920, in _create_folders
    project_path.joinpath(path).mkdir(exist_ok=True)
  File "c:\users\chris\appdata\local\programs\python\python39\lib\pathlib.py", line 1313, in mkdir
    self._accessor.mkdir(self, mode)
FileNotFoundError: [WinError 2] The system cannot find the file specified: 'C:\\Users\\Chris\\Documents\\Brownie\\build'

How can it be fixed?

This can be fixed by changing line 920 in brownie/project/main.py from: project_path.joinpath(path).mkdir(exist_ok=True) to: project_path.joinpath(path).mkdir(exist_ok=True, parents=True)
