NPS WARNING: *external sender* verify before acting.

I did a bit of messing around with my virtual environment and versions of
x3d.py. I noticed with version 4.0.51, there was an x3d folder in
site-packages with the code in it.  So somehow, in the 4.0.60 releases, the
x3d folder (the code) was left out? 

Hope this helps!

I tried adding necessary files to my virtual environment without luck.  Here
also is my system installed x3d: 

john at DESKTOP-8OPL3IE MINGW64
/c/Python310/Lib/site-packages/x3d-4.0.60.dist-info
$ ls
INSTALLER  LICENSE  license.html  license.txt  METADATA  RECORD  REQUESTED
top_level.txt  WHEEL

Again, no code???  Good luck!  Don't forget to deploy code to package
distribution.  Maybe there's something with your network which is preventing
files from upload?  Are you uploading the files from a different machine or
network?

I haven't made much progress, but when installing x3d.py in a virtual
environment: 

$ py -m venv venv

$ source venv/Scripts/activate

$ pip install x3d

$ python -m pip install --upgrade pip

$ pip3 install --upgrade x3d
Requirement already satisfied: x3d in c:\x3d-code\www.web3d.org

$ ls

**** no code ???  ***

I'll look at the way to deploy a package and see if I see anything, but I
have no experience.

Thanks Moritz for looking at this.  However, we can’t really expect any PyPi
user who types “pip install x3d” to go through such a process.

Does latest version work for you? Presumably you are getting the same
problem
 test reports are helpful.

Perhaps my local installation is incorrect
 am just using stock latest
python installer from python.org

.  I will do a complete uninstall/reinstall of python 3.10.latest.

Our goal is simplicity.  Still trying to find right incantation in our
__init__.py for PyPi.

all the best, Don

5.   Bad news, still no joy.  Following “pip install x3d” and hiding
PYTHONPATH, the PyPi version installed via pip still fails, now saying:

That means that it's simply not finding the location where it's been
installed to. Depending on how your Python is installed (provided by your
operating system, conda, complied by hand yourself) it may be set up to look
at different locations by default.

> pip show x3d

(after running pip) should show you where the files went. How does Python
know where to look? Again, that depends on how it was installed. Usually,
that's the same place where pip installed stuff, but apparently that's not
the case here. Maybe the pip is not the same one as the Python. That can
happen when there are several Python version installed on the same system,
e.g. one is installed using conda and one is provided by the operating
system.

Typically, they are in the same location:

(base) MoritzAirRoseGold ~> which pip
/Users/guenther/mambaforge/bin/pip
(base) MoritzAirRoseGold ~> which python
/Users/guenther/mambaforge/bin/python

In that case, pip will install to a directory that python looks into when
using "import".

If instead, the package is installed at a different location, then
PYTHONPATH should be set to the base directory of the packages, i.e. if you
have packages:

/my/dir/x3d

/my/dir/otherpackage1

/my/dir/otherpacakge2

then PYTHONPATH=/my/dir

not "/my/dir/x3d" (because that way python would look for
/my/dir/x3d/x3d/__init__.py, so one level of x3d too many).
