Embedded 3.6.0 distribution does not insert script parent in sys.path[0], but the normal python do it.

this make some failed, like when I try to do pip install future, it will failed as import src.future failed, which works for normal python.

The root source maybe when python36._pth exist, python rewrite the flag and mark as isolate mode automate, which will not update sys.path when pymain_init_sys_path.

I use a trick which is really bad as a work around(and even when site .main the sys.argv is not ready!), and hope upstream will fix the root source.

BTW, where is Embedded distribution package script in python git repo?

This is the intentional design of the embedded distribution. You need to update the ._pth file to include the directories that have files that are part of your app - it's not meant for running random scripts, that's the job of the normal distribution.

The build script files are in Tools/msi with the other installer files, primarily make_zip.py, though that also gets used for the Nuget packages.
