pyside6-deploy FileNotFoundError: [WinError 206] The filename or extension is too long

[martinbrader]

@jsulm I assume the filename is generated by pyside6-deploy but I do not know how to find out what it is. When I look inside their Python code it isn't clear to me where the filename is generated.

but I do not know how to find out what it is

Isn't it printed along the error message?

[Shyamnath]

How does your "pyside6-deploy" command look like? When you run it for the first time, it will generate a pysidedeploy.spec file inside the project. Can you change "--quiet" to "--verbose" for the "extra_args" field. so that you get more information on the error

[martinbrader]

@Shyamnath I changed the spec file as you suggested, but it doesn't seem to output any more clues?
here is how I amended pyside-deploy.spec:

[nuitka]
# (str) specify any extra nuitka arguments
# eg = extra_args = --show-modules --follow-stdlib
extra_args = --verbose

and this was the console output:

DEPRECATION: nuitka is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change.
A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

@martinbrader said in pyside6-deploy FileNotFoundError: [WinError 206] The filename or extension is too long:

pyside6-deploy.exe

I never used it, but maybe there is a way to get more verbose output from it (often -v parameter is used for that)?

[Shyamnath]

@martinbrader Can you please do a "pyside6-deploy --dry-run", so that i see what Nuitka command is being run

pyside6-deploy is basically a wrapper around Nuitka. I think this might be a Nuitka error. I would know for sure from the command being run.

[JonB]

@martinbrader
First you should do as @Shyamnath asks.

Just an observation which might help. Immediately before the "Traceback" the output shows

ERROR:root:[DEPLOY]: None not found

None is the Python keyword for a "null"/no value. I think you will find the script is not expecting something to be None at this point, indicating it has already gone wrong. If you can discover what it is that is returning None when it should be returning something else (a filepath here?) that might show what the problem is. Don't know whether this might help.

[martinbrader]

@Shyamnath I ran pyside6-deploy.exe --dry-run as you suggested.
The output is too large for a single post.
It consists of two lines, the second of which is 101917 chars long.
Here is the first line and around the first 1,000 chars of line 2.
NB the rest of line 2 is just more of the same with different paths:

Although you may not wish to, if you installed to a path shorter than E:\Martin\MyDocs\Data\Python\Trials_v2\DHFS_problem\Trial6_checker.venv at the start does the error go away?

Did you think this might be worth giving a try?

[martinbrader]

@JonB Yes I reinstalled in d:\Trial9 and got same error!

[Shyamnath]

@martinbrader hmm, the command being run looks correct to me. Can you try running the example from the "editingmodel" folder? If that does not work, can you report a bug with the "--dry-run" ouput and I can take a look at whats wrong

Here is how you could report a bug: https://wiki.qt.io/Qt_for_Python/Reporting_Bugs

[martinbrader]

@Shyamnath I'm afraid same error as before when I tried with:
.venv\Lib\site-packages\PySide6\examples\gui\analogclock.main.py.
