dist .exe does not seem to be self-contained, only runs in original location

[Ken Sullivan]

I'm running into a runtime error when trying to run the pyinstaller generated executable on another machine, or the same machine but dist directory has moved, or even just called from a lower subdirectory, e.g. D:\> base-folder\project\dist\main\main.exe instead of D:\base-folder\project\dist\main> main.exe (though D:\base-folder\project> dist\main\main.exe works). The error trace is:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Exception: Versioning for this project requires either an sdist tarball, or access to an upstream git repository. It's also possible that there is a mismatch between the package name in setup.cfg and the argument given to pbr.version.VersionInfo. Project name mock was given, but was not able to be found.

If I run with --debug=imports, the lines immediatly preceding the exception are:

import 'sphinx.setup_command' # <pyimod03_importers.FrozenImporter object at 0x000002749B2CF048>

import 'pbr.builddoc' # <pyimod03_importers.FrozenImporter object at 0x000002749B2CF048>

import 'pbr.packaging' # <pyimod03_importers.FrozenImporter object at 0x000002749B2CF048>

When it works (ran in original location), those lines are followed with:

import 'mock.mock' # <pyimod03_importers.FrozenImporter object at 0x0000023DF208F048>

import 'mock' # <pyimod03_importers.FrozenImporter object at 0x0000023DF208F048>

<many more lines...>

I wasn't able to get it to complete with --debug=all.

pyinstaller is installed and ran within a WinPython command prompt. I had to edit the .spec file to increase the recursionlimit to 5000, and to add some hiddenimports. OS is Windows 10, 64-bit.

Anything I could be doing wrong, or anything to try?

To compile use --onefile option.

pyinstaller --onefile <filename>.py

This should work and if you want to suppress the console window compile as follows:

pyinstaller --onefile -w <filename>.py

Hope this helps

Try compiling with the --onefile option

pyinstaller --onefile <filename>.py
