This started happening this past week, and, while it's worked fine in
the past, the moment I try to launch the pyinstaller process at all, to generate compiled output, or even if just launch it with no command line options, I receive the following error message:

pkg_resources.DistributionNotFound: The 'altgraph' distribution was not
found and is required by the application


The full contents of the output string when I even try to just launch pyinstaller with no commands/arguments is the following:

# ---end of output---


I have tried completely removing python's installation, and,
reinstalling it, but, same issue more or less immediately.


If I freeze pip's installed list within this specific virtual
environment, it lists the following:

altgraph==0.17.4
packaging==24.0
pefile==2023.2.7
pyinstaller==6.5.0
pyinstaller-hooks-contrib==2024.3
pywin32-ctypes==0.2.2

# ---end of requirements.txt---


And, if, just for testing, I launch python interpreter, and, ask it to
import altgraph, it provides the same last line of error output?


If relevant, running with python 3.11.8, under windows 11 64-bit, and,
can't think of anything that specifically occurred/changed this past
week, besides normal things like windows updates, etc., but, don't
really think that's likely to be relevant, unless something to do with
pywin32 has caused an issue?


Should I try installing python 3.12 version instead and see if it changes?


Also, if relevant, while running under latest up-to-date version of
windows 11 64 bit, have in any case enabled case-sensitivity on the
folder I store all my python code in, just in case.


TIA

As in, most of them are mentioning older versions of python, and, mainly different platforms - mac and linux, but, various google searches have not mentioned much of using it on windows, and having it just stop working.

Now did even try shifting over to python 3.12, but, still no-go.

If launch pyinstaller under python 3.10 on this exact same machine, pyinstaller runs - just keep that older version hovering around for a couple of occasional tests, partly since some of my target environments are still running older versions of python, but anyway.

Also, not really relevant, but, cx_freeze is perfectly able to generate executables for this same code, but, then not combining all output into a single file - will stick to that for now, but, not always as convenient, and, still wondering what changed here.

Ok, last update for now - checked out the following page on
pyinstaller.org, and, ended up posting to the mailing list, so, let's see:

Ok, had received response on pyinstaller mailing list, but, also just
related to trying clean uninstall/reinstall of modules, but, while
checking that out, something else occurred to me, and, it now operates
as it should.


Anyway, what seemed to be causing issue was actually that, since, while
am working under windows 11, quite often you might need to work with case-sensitivity in file names, not by choice, but, since a lot of
target platforms, like linux, etc. are case-sensitive, and, at times,
when working with external modules, this might cause hassles, etc.


In other words, the folder/directory where all my python source code is
stored is set to be case-sensitive - there are a couple of ways to
implement this under windows 10 and windows 11, via some external
utilities, or by running the following command from a
terminal/power-shell window, running it as administrator:

fsutil.exe file SetCaseSensitiveInfo C:\folder\path enable


If you instead use disable argument at the end, it then disables case-sensitivity, and, what did now was, under current project/test
code, I created an additional sub-folder, copied code files, etc. over
into it, disabled case-sensitivity on it, recreated the virtual
environment, and installed all required modules, including pyinstaller
using pip, and, when I then run pyinstaller from there, it works fine,
and, does what I want it to.


In other words, something to do with having case-sensitivity enabled recursively on the folder/directory containing the code and the virtual environment seemed to be causing these errors/issues, specific to
altgraph, which doesn't really make sense to me, but, it's now working,
so, will archive this to memory, for later reference.
