Answer 1

The output of print(abspath(".")) when running directly in python is:

C:\Users\myname\eclipse-workspace-tms\test_unzip_exe

While running with pyinstaller is:

C:\Users\myname\eclipse-workspace-tms\test_unzip_exe\dist\test

Thus, the archive is not extracted in the dist\test folder.

Fix this by setting path to return value of abspath(".") instead of hard-coding it to C:\Users\myname\eclipse-workspace-tms\test_unzip_exe

Answer 2

The problem is, as you found in your 2nd edit, that pyunpack needs patool installed on the target system - which, in turn, requires python.

To fix this you need to:

• Use tarballs or zipfiles; shutil supports theses.

• Or require the end user to have python installed.

Another way of putting it is that to use pyunpack with pyinstaller, you need python on the target system.
