Hello.

FancyURLopener and URLopener have been removed from Python 3.14 (they have been deprecated since Python 3.3) and that means that this code will no longer work:

node/tools/configure.d/nodedownload.py

Lines 24 to 27 in 8aa0513

class ConfigOpener(FancyURLopener):
"""fancy opener used by retrievefile. Set a UA"""
# append to existing version (UA)
version = '%s node.js/configure' % URLopener.version

If you still need this functionality to set a custom user agent, I can propose a solution that will work with a newer Pythons.
