ValueError "Expected version spec" when installing local wheel via pip
23,289
Solution 1
I was using a very out-of-date version of PIP.
$ pip -V
pip 1.3.1 from C:\Python27\lib\site-packages (python 2.7)
I upgraded to pip 6.0.8
and all is well.
Solution 2
Using the Ubuntu 14.04 AMI on AWS, I found I had to upgrade setuptools
:
sudo pip3 install -vU setuptools

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_wheel
with this setup.py file:#!/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:
Exception: Traceback (most recent call last): File "C:\Python27\lib\site-packages\pip\basecommand.py", line 139, in main status = self.run(options, args) File "C:\Python27\lib\site-packages\pip\commands\install.py", line 235, in run InstallRequirement.from_line(name, None)) File "C:\Python27\lib\site-packages\pip\req.py", line 118, in from_line return cls(req, comes_from, url=url) File "C:\Python27\lib\site-packages\pip\req.py", line 43, in __init__ req = pkg_resources.Requirement.parse(req) File "build\bdist.win32\egg\pkg_resources\__init__.py", line 2929, in parse reqs = list(parse_requirements(s)) File "build\bdist.win32\egg\pkg_resources\__init__.py", line 2876, in parse_requirements "version spec") File "build\bdist.win32\egg\pkg_resources\__init__.py", line 2841, in scan_list raise ValueError(msg, line, "at", line[p:]) ValueError: ('Expected version spec in', 'dist/mypkg-0.0.1-py2-none-any.whl', 'at', '/mypkg-0.0.1-py2-none-any.whl') Storing complete log in C:\Users\tbhartman\pip\pip.log
What is the problem and how to I fix it?
