[issue24960] Can't use pip or easy_install with embeddable zip file.

[fourplusone]

fourplusone added the comment:

The problem is indeed that lib2to3 fails to load the Grammar.txt file if it is 
located inside a .zip archive.

I think one way to fix it is using of the "get_data" function of the loader  
https://docs.python.org/3/library/importlib.html#importlib.abc.ResourceLoader.get_data

However, this would make caching the Grammar more difficult, as one cannot 
write back the pickled dict to a zip file

Alternatively one could generate an importable *.pyc file from the grammar 
during the build process

FileNotFoundError: [Errno 2] No such file or directory: 
'...\\python-3.5.0-embed-amd64\\python35.zip\\lib2to3\\Grammar.txt'


triggered e.g. by "python setup.py --help-commands" (when building setuptools)

workaround is to extract "...\python-3.5.0-embed-amd64\python35.zip" into a 
__directory__ named exactly the same (hence a directory named "python35.zip" 
which replaces the original zip file)

This looks more like lib2to3 doesn't support running from a .zip archive.

[Oleg N]

New submission from Oleg N:

Error: [Errno 2] No such file or directory: 
'...\\python35.zip\\lib2to3\\Grammar.txt'. Python35.zip from this archive: 
https://www.python.org/ftp/python/3.5.0/python-3.5.0rc2-embed-amd64.zip. Path 
is correct.
