Setup.py尝试导入正在安装的软件包

Question

UPDATE This is a bug in the setup.py of the package

---

Attempting to install certain packages using pip and I get this error:

pip install saspy

command python setup.py egg_info failed with error code 1

Upon reading the traceback I see that it failed while attempting to import saspy.This is an excerpt from the setup.py which is indeed attempting to import from saspy, while installing saspy. How is this supposed to work? I am using setuptools 36.0.1, pip 9.0.1 and (long story) python 2.7.8.

try:
  from setuptools import setup
except ImportError:
    from distutils.core import setup

from saspy import __version__

with open('README.md') as f:
    readme = f.read()

Answer 1

This is a buggy setup.py. It's a common mistake, since with a source installation, you can import the package from the unpacked source tree before it's been installed.

Answer 2

saspy requires Python3. I would expect this issue is due to using Python2 to try to install it. Though I have never seen that error before when installing it.
