“pip freeze”因包装安装而中断

我正在使用dependency_links安装包。它似乎安装了软件包,但破坏了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,我会收到以下错误。

pip freeze

pip install . --extra-index-url--trusted-host可以解决问题,如果您想以可编辑模式安装它,您可以执行pip install -e .

您可能仍想查看列出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

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