`pip freeze`打破包安装

Question

我正在使用dependency_links安装包。 它似乎安装了软件包，但打破了pip冻结功能（这可能意味着存在更深层次的安装问题。）我希望能够从自定义服务器下载软件包，而无需在运行setup.py之外进行任何设置。

这是我的setup.py文件：

from setuptools import setup

  setup(
      name='package'
      ,version='0.1.0'
      ,packages=['foo',
                 'bar'
                 ]
      ,long_description=''
      ,url='https://github.com/myrepo'
      ,install_requires=['numpy>=1.9.2'
                         ,'some_package'
                         ]
      ,dependency_links=[
          "http://custom_server/packages/some_package-0.1.0.tar.gz"
      ]               
  )

安装似乎工作正常，但如果我尝试运行pip_freeze我得到以下错误。

pip freeze

pip install . 使用--extra-index-url和--trusted-host可以解决这个问题，如果你想在可编辑模式下安装它，你可以执行pip install -e . 。

您可能仍希望查看列出dependency_links和zip_safe选项： https ： //pythonhosted.org/setuptools/setuptools.html#dependencies-that-aren-t-in-pypi https://pythonhosted.org/setuptools/ setuptools.html＃setting-the-zip-safe-flag https://github.com/irqed/octokit.py/blob/master/setup.py#L51

顺便说一句，你也可以在pip requirements.txt文件中指定--extra-index-url和--trusted-host 。
