bench build causes: TypeError: expected str, bytes or os.PathLike object, not NoneType

[casesolved-co-uk]

Still getting this problem, but now when requesting a page from the running site too. For some reason importlib is treating press differently to other apps:

In [9]: frappe.get_module('press')
Out[9]: <module 'press' (<_frozen_importlib_external._NamespaceLoader object at 0x7fdda60bdff0>)>

In [11]: frappe.get_module('press').__file__

In [13]: frappe.get_module('frappe').__file__
Out[13]: '/home/frappe/v15/apps/frappe/frappe/__init__.py'

frappe: 15.34.1

For anyone else having build problems, here are some tips:

• Use the master branch of press (the latest tag is years old)
• Remove other apps on your bench (or start a fresh one)
• Use frappe version-15
• Use node v18
• Use python 3.11
• Use at least 2GB RAM and some swap for building

[casesolved-co-uk]

Okay, this was caused by there being a site with the same name as the frappe app: press

In [3]: press.__loader__._path
Out[3]: _NamespacePath(['/home/frappe/v15/sites/press'])

I'll log a frappe bug
