ValueError "Expected version spec" when installing local wheel via pip
提问by tbhartman
I have a closed-source Python module I am developing and would like to share with people in my workplace. I have built a wheel via setup.py bdist_wheelwith this setup.py file:
我有一个正在开发的闭源 Python 模块，想与我工作场所的人分享。我setup.py bdist_wheel用这个 setup.py 文件构建了一个轮子：
#!/usr/bin/env python
from setuptools import setup, find_packages
setup(name='mypkg',
version='0.0.1',
description='tools for work',
author='tbhartman',
packages=find_packages('src', exclude=['test*']),
package_dir = {'':'src'},
entry_points={
'console_scripts':[
'runtool = mypkg.run:main',
],
},
install_requires = ['argparse'],
classifiers = [
'Development Status :: 3 - Alpha',
'Programming Language :: Python :: 2',
]
)
I want to test the installation process, so I try pip install dist\mypkg-0.0.1-py2-none-any.whl and get the following traceback:
