Issue 22315: TypeError in error handling in distutils.dir_util.copy_tree (original) (raw)

This morning, I was running an install of a package on Python 3.4.1 when I encountered this error:

C:\Users\jaraco\projects\jaraco.financial [default tip]> ./setup install running install running bdist_egg running egg_info writing namespace_packages to jaraco.financial.egg-info\namespace_packages.txt writing jaraco.financial.egg-info\PKG-INFO writing top-level names to jaraco.financial.egg-info\top_level.txt writing requirements to jaraco.financial.egg-info\requires.txt writing dependency_links to jaraco.financial.egg-info\dependency_links.txt writing entry points to jaraco.financial.egg-info\entry_points.txt writing manifest file 'jaraco.financial.egg-info\SOURCES.txt' installing library code to build\bdist.win-amd64\egg running install_lib running build_py copying jaraco\financial\records.py -> build\lib\jaraco\financial creating build\bdist.win-amd64\egg creating build\bdist.win-amd64\egg\jaraco creating build\bdist.win-amd64\egg\jaraco\financial copying build\lib\jaraco\financial\ledger.py -> build\bdist.win-amd64\egg\jaraco\financial copying build\lib\jaraco\financial\qif.py -> build\bdist.win-amd64\egg\jaraco\financial copying build\lib\jaraco\financial\merchant.py -> build\bdist.win-amd64\egg\jaraco\financial Traceback (most recent call last): File "C:\Program Files\Python34\lib\distutils\dir_util.py", line 126, in copy_tree names = os.listdir(src) OSError: [WinError 59] An unexpected network error occurred: 'build\lib\jaraco\financial\records.py'

During handling of the above exception, another exception occurred:

The original traceback indicates a network error occurred. The secondary error occurs when the error is assumed to be an iterable of two elements. I suspect this issue arises from the conversion of WindowsError to OSError or similar.

I plan to look at this in more depth later.
