`pip freeze` 因软件包安装而中断

Question

我正在使用 dependency_links 安装一个包。它似乎可以正常安装软件包，但会破坏 pip freeze 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ning [之外进行任何设置 setup.py.

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 我会收到以下错误。

pip freeze

pip install . 与 --extra-index-url 和 --trusted-host 就可以了，如果你想以可编辑模式安装它，你可以 pip install -e ..

您可能仍想查看清单 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

顺便说一下，您也可以在 pip requirements.txt 文件中指定 --extra-index-url 和 --trusted-host。
