通過pip安裝本地車輪時出現ValueError“預期版本規格”

Question

我有一個正在開發的開源Python模塊，並希望與工作場所的人們共享。 我已經使用setup.py文件通過setup.py bdist_wheel構建了一個轉輪：

#!/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',
          ]
     )

我想測試安裝過程，所以我嘗試pip install dist \\ mypkg-0.0.1-py2-none-any.whl並獲得以下回溯：

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')

有什么問題，我該如何解決？

Answer 1

我使用的是PIP的過時版本。

$ pip -V
pip 1.3.1 from C:\Python27\lib\site-packages (python 2.7)

我升級到pip 6.0.8 ，一切都很好。

Answer 2

在AWS上使用Ubuntu 14.04 AMI，我發現我必須升級setuptools ：

sudo pip3 install -vU setuptools
