Latest Build Runtime Error

[esampson]

I've had this error both with an absolutely clean Cygwin install (the only options turned on were python-2.7, setuptools, can gcc) and with Ubuntu (I didn't do an absolutely clean Ubuntu build since it is the identical error)

After copying the source code of the latest build to the clean environment I run python setup.py build and python setup.py install (or sudo python setup.py install in Ubuntu). It installs fine but when I run the command "worldengine" I get the following error:

Traceback (most recent call last): File "/usr/bin/worldengine", line 9, in load_entry_point('worldengine==0.18.0', 'console_scripts', 'worldengine')() File "/usr/lib/python2.7/site-packages/pkg_resources/init.py", line 552, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python2.7/site-packages/pkg_resources/init.py", line 2672, in load_entry_point return ep.load() File "/usr/lib/python2.7/site-packages/pkg_resources/init.py", line 2345, in load return self.resolve() File "/usr/lib/python2.7/site-packages/pkg_resources/init.py", line 2351, in resolve module = import(self.module_name, fromlist=['name'], level=0) File "/usr/lib/python2.7/site-packages/worldengine-0.18.0-py2.7.egg/worldengine/cli/main.py", line 12, in from worldengine.imex import export ImportError: No module named imex

Does this file exist?

worldengine/imex/__init__.py

Do remember that the master branch is development... not a release, so we've not tested actually making a package/installing it.

If you want to run/develop worldengine, just git clone the repo, create a virtualenv, source venv/bin/activate and then: python worldengine

[esampson]

Yes, the file does exist. I should also note that if I go to cli/main.py and edit out the line "from worldengine.imex import export" everything runs fine. Apparently the latest code wants to import the functions but then it never seems to use them.

[psi29a]

The latest code works for me and uses what is imported, I make a point to make sure that we never import methods that are never used. I wonder if it either something to do with your environment. To be honest, I've not tried to 'python setup.py install' maybe that is it?

Have you tried creating a virtualenv and running the code in place without installing it?

Try running the CLI with the export params, and you'll have a crash telling you calling an unknown method... likely the ones you commented out.

[esampson]

That is possibly it. I am running it from the install. Can you give me an example CLI command for me to test?

[psi29a]

virtualenv venv
source venv/bin/activate
pip install -r requirements2.txt
python worldengine

This can be found in our README.md: https://github.com/Mindwerks/worldengine#install-dependencies

[esampson]

Ok. Completely clean install on Cygwin with Python, GCC, and Setuptools. Setuptools was then used to install pip and virtualenv. Created and switched to virtualenvironment venv, ran the pip install.

Then I ran the worldengine command:

$ python worldengine

Didn't mean to close the issue. Wrong button.

Looks like zlib isn't available in your cygwin environment.

I'm going to go out on a limb here and ask why you are using Cygwin instead of native windows python. I've not tested on cygwin and I hope to avoid doing so. ;)

I wrote the procedure you can follow here: https://github.com/Mindwerks/worldengine#windows

I just want to add that I stumbled upon the missing imex-module, too. As far as I can tell it might be because the imex-folder is empty and lacking the file export.py that is supposed to be imported. Where is export.py? It is not part of the master-branch.

https://github.com/Mindwerks/worldengine/tree/master/worldengine/imex

EDIT: The last release (0.18) didn't have that folder yet: https://github.com/Mindwerks/worldengine/tree/v0.18.0/worldengine

[psi29a]

There is no export.py, everything in inside

worldengine/imex/__init__.py

which is intentional. This is something I'll look into later, but for now it works as-is when using virtualenv which currently the only supported method of use.
