pex.resolver.Untranslateable when using setup from setuptools

[bqm]

Hello,

I am trying to build a pex file with several requirements and my own package that has a setup.py.

From reading pex --help, I understand that I need to use the -s to provide the directory that contains my setup.py file.

I get this error:

pex -s . -e greatpackage.script -o output.pex
**** Failed to install greatpackage-0.1. stdout:

**** Failed to install greatpackage-0.1. stderr:
Traceback (most recent call last):
  File "<stdin>", line 6, in <module>

    raise Untranslateable('Package %s is not translateable.' % package)
pex.resolver.Untranslateable: Package SourcePackage('file:///Users/bqm/.pex/build/greatpackage-0.1.tar.gz') is not translateable.

Here is a way to reproduce my error:

mkdir reproducible
cd reproducible
virtualenv env
. env/bin/activate
pip install wheel
pip install pex
mkdir greatpackage
echo '
from setuptools import setup, find_packages

setup(
    name="greatpackage",
    version="0.1",
    author="bqm",
    packages=find_packages(),
    scripts=["greatpackage/script.py"]
)' > setup.py

touch greatpackage/__init__.py

echo '
if __name__ =="__main__":
  print "Hello world!"
' > greatpackage/script.py

pex -s . -e greatpackage.script -o output.pex

Am I missing something? What am I doing wrong?
Thanks

I forgot to mention:
I am using macosx 10.10 and python 2.7.6

I have not dug into pip code to see how it special cases for this, but pex -s does not auto-include setup.py so you'll need a MANIFEST. Additionally, instead of installing wheel, you just need to --no-wheel for now.

A working example built off yours:

mkdir reproducible
cd reproducible
virtualenv env
. env/bin/activate
pip install pex
mkdir greatpackage

cat << EOF > setup.py
from setuptools import setup, find_packages

setup(
    name="greatpackage",
    version="0.1",
    author="bqm",
    packages=find_packages(),
    scripts=["greatpackage/script.py"]
)

EOF

cat << EOF > MANIFEST.in
include *.py

EOF

touch greatpackage/__init__.py

cat << EOF > greatpackage/script.py
if __name__ == "__main__":
  print("Hello world!")

EOF

pex --no-wheel -s . -e greatpackage.script -o output.pex
./output.pex
