For example, Jython 2.7. When we try to execute `jython-standalone -m pip`, distutils.sysconfig tries to parse sys.executable as a path and obviously fails: Traceback (most recent call last): File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/runpy.py", line 161, in _run_module_as_main File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/runpy.py", line 72, in _run_code File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/ensurepip/__main__.py", line 4, in <module> File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/ensurepip/__init__.py", line 220, in _main File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/ensurepip/__init__.py", line 123, in bootstrap File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/ensurepip/__init__.py", line 45, in _run_pip File "/tmp/tmp9QnVEm/pip-1.6-py2.py3-none-any.whl/pip/__init__.py", line 10, in <module> File "/tmp/tmp9QnVEm/pip-1.6-py2.py3-none-any.whl/pip/util.py", line 13, in <module> File "/tmp/tmp9QnVEm/pip-1.6-py2.py3-none-any.whl/pip/backwardcompat/__init__.py", line 115, in <module> File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/distutils/sysconfig.py", line 28, in <module> File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/posixpath.py", line 367, in realpath File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/posixpath.py", line 373, in _joinrealpath File "/home/ale/dev/3toj/jython-standalone-2.7.0.jar/Lib/posixpath.py", line 61, in isabs AttributeError: 'NoneType' object has no attribute 'startswith' | |||

I'm not sure it is reasonable to expect distutils to work if sys.executable is not valid. What do you think distutils could do instead? | |||

Well, project_base (which is what sys.executable is used for) is used only during build (i. e. python_build is True), if I understand it correctly. Normally, sys.prefix and sys.exec_prefix are used for all the paths.Also, project_base can be explicitly set using _PYTHON_PROJECT_BASE environ variable, in which case we still don't need sys.executable (but it still would fail without one right now). | |||

Yes, you are right; I was thinking that distutils and/or pip re-executed python for certain tasks, but upon reflection I don't think they do. | |||

We re-execute Python to run setup.py. Even from wheels we do it to compile pyc files. Sent from my iPhone> On Oct 29, 2016, at 2:38 PM, R. David Murray <report@bugs.python.org> wrote:> > > R.

This issue can be reproduced with:diff --git a/Lib/site.py b/Lib/site.pyindexad1146332b..c850109c19 100644--- a/Lib/site.py+++ b/Lib/site.py@@ -638,3 +638,5 @@ def _script(): if __name__ == '__main__': _script()++sys.executable = NoneAttachedPR 12875 fix distutils.sysconfig and the distutils build command if sys.executable is None or an empty string. I don't expect that everything works magically, but at least, it's possible to run "./python -m distutils.sysconfig" and use "make" in Python which runs "./python -E ./setup.py build". I'm surprised, but setup.py is able to build C extensions using sys.executable = None :-)I made a similar fix for sysconfig inbpo-7774: commit171ba0504aa778d81346ea56fc9000b29d4d3e1d. | |||

I fixed the bug in Python 2.7, 3.7 and master branch (future 3.8).Thanks Alexander P for the bug report ;-) | |||
