Try to create a GHA with pyapp 0.29.0, to build a (embbeded) win/exe ... [RESOLVED]

[manatlan]

INTRODUCE ME :

I'm working on http://github.com/manatlan/reqman ...
I already release a windows executable, thru a GHA with pyinstaller.
I've red this : https://www.infoworld.com/article/4030697/pyapp-an-easy-way-to-package-python-apps-as-executables.html
and wanted to try the "pyapp" system (to replace the pyinstaller version)
I'm not really a specialist of rust, of windows .. and GHA.
So I asked gemini-pro(thru jules) to create a GHA for me, with pyapp 0.29.0:
Here it is : https://github.com/manatlan/reqman/blob/master/.github/workflows/build_win_pyapp_test.yml

MY PROBLEM:

It's not working OOTB, see here:

https://github.com/manatlan/reqman/actions/runs/18615821245/job/53080192148

the relevant errors seems to be related to :

error: failed to run custom build command for `pyapp v0.29.0 (D:\a\reqman\reqman\pyapp-0.29.0)`
Caused by:
  process didn't exit successfully: `D:\a\reqman\reqman\pyapp-0.29.0\target\release\build\pyapp-00a08bb2fffbcc62\build-script-build` (exit code: 101)

  --- stderr
  thread 'main' panicked at build.rs:645:13:
  Project path is not a file: dist/reqman-0.0.0-py3-none-any.whl

Can anyone point me to the right direction ?

I've tested a lot of things ... but it won't ;-(
latest errors are always the same (see https://github.com/manatlan/reqman/actions/runs/18616436704/job/53081561550):

    thread 'main' panicked at build.rs:645:13:
    Project path is not a file: .\reqman-0.0.0-py3-none-any.whl

But I can ensure that "reqman-0.0.0-py3-none-any.whl" is a file ;-)

you should change the message, because it's not helpful at all ;-)

When building the Cargo installation rather than the local repository method the paths must be absolute because the current directory is different.

Thanks @ofek
I go further ... (https://github.com/manatlan/reqman/actions/runs/18616753187/job/53082335416)

     Invalid project name ``; must only contain ASCII letters/digits, underscores, hyphens, and periods, and must begin and end with

[ofek]

I don't have further time to offer troubleshooting assistance but the project name is empty somehow. The call chain is as follows:

• pyapp/build.rs

  Line 666 in 9521dc9

  set_project_from_metadata(&metadata, &entry_path);

• pyapp/build.rs

  Line 601 in 9521dc9

  normalize_project_name(&captures[1].to_string())

• pyapp/build.rs

  Line 457 in 9521dc9

  panic!(

Try printing out the contents of the embedded *.dist-info/METADATA file.

@ofek no problem !
I've reached to make it work, by forcing PYAPP_PROJECT_NAME: "reqman"
And it produces a windows executable : which works on win11 ! 🥇 (https://github.com/manatlan/reqman/actions/runs/18616988063)
Thanks a lot !
that's a great project !

EDIT:
I've reached to embbed all my dependencies, and compress (with UPX).

So my win/exe size (py3.14 + pyapp 0.29.0 + (UPX or not) ) is 21Mb
Compared to my pyinstaller version (py3.14 + pyinstaller latest + UPX) is 12.4Mb

There is a difference of 8Mb ;-(

is it possible to try to reduce more ?
