installed script lacks "-E" in their shebang

I installed pyflakes through pipx, but using the tool in another context fails, because that other context set a PYTHONPATH that interfer with pyflakes import.

How to reproduce

pyflakes installed with Python 3.12, somehow a script added an element to PYTHONPATH that contains a re module compile for Python 3.11. pyflakes wrongly pick up the PYTHON PATH instead of sticking within its venv.

   $ pyflakes --version
+  Traceback (most recent call last):
+    File "HOME/.local/bin//pyflakes", line 3, in <module>
+      import re
+    File "OTHER/re/__init__.py", line 125, in <module>
+      from . import _compiler, _parser
+    File "OTHER/_compiler.py", line 18, in <module>
+      assert _sre.MAGIC == MAGIC, "SRE module mismatch"
+             ^^^^^^^^^^^^^^^^^^^
+  AssertionError: SRE module mismatch
+  [1]

Expected behavior

I would expect pipx to install standalone, isolated environment that are not affected by external factor. This expectation fails here.

Possible fixes ?

Install tools with -E in their shebang for appropriate isolation. I fixed my install that way.
