easy_install無法安裝軟件包

Question

我正在嘗試為我的python項目編寫一個setup.py文件：

import os
from setuptools import setup, find_packages
here = os.path.abspath(os.path.dirname(__file__))

requires = [
        'requests',
        'simplejson',
        'logging',
        'rfc3987',
    ]

setup(name='xxxxxxx',
      version='0.1',
      description='xxxxxxx API',
      url='https://github.com/xxxxxxxx',
      packages=find_packages(),
      include_package_data=True,
      zip_safe=False,
      install_requires=requires,
      ) 

當我執行它時，我得到這個錯誤：

如果我只嘗試easy_install rfc3987遇到相同的錯誤。

有什么辦法可以解決這個問題？

Answer 1

rfc3987聲稱它可以在Python 2.7和3.x上運行。 您正在嘗試將其安裝在2.6上。 所以失敗了。

該問題與您自己的軟件包或easy_install無關。 如果您手動下載tarball並運行python2.6 setup.py install ，則會遇到相同的錯誤。 實際上，至少在1.3.1中，有類似Python 函數這樣的代碼在Python 2.6下顯然是不合法的。

從git歷史記錄來看，似乎已經進行了一些更改使其與Python 2.6兼容，因此下一個發行版可能會起作用。 在此之前，您將無法從2.6開始使用它。
