I asked why, on Ubuntu, the boot loader of a one-dir bundle is failing with
"No such file or directory: ...orig-prefix.txt' (the full traceback is
below).
I have investigated further. I omitted to mention that I was running
Python3 and PyInstaller, in a virtual environment.
It turns out that orig-prefix.txt is a file that virtualenv creates and
stores in the lib/ directory of the VENV.
In Pyinstaller/build_app.py it is mentioned twice. Once in get_runtime()
and later with almost identical code, in create_binaries(). In both cases
its contents are used to get the path prefix to find the Python interpreter.
So why is it also being referenced from the bootloader? It turns out that
the bootloader is loading what it thinks are needed built-in modules. In
pyi_importers.load_module(), it is loading something called "site.py".
The site.py in my VENV starts out, literally like the 5th statement
executed, with
f = open(os.path.join(os.path.dirname(__file__), 'orig-prefix.txt'))
However, it is not running in a VENV, it is running in a one-dir (or a
one-file, same problem) PyInstaller bundle. The virtualenv is long gone. So
there is no file orig-prefix.txt.
Can anyone help me understand what is going on and how to fix this?
Thanks,
Dave Cortesi
