Question

我正在尝试将ScientificPython列为我setup.py中的依赖项。但是，在安装过程中，python似乎找不到包。我的做法有什么问题？

这是我的设置：

import setuptools
setuptools.setup(name = 'MyPack', version = '0.1', 
  description= 'Description.',
  author = 'Me',
  packages = setuptools.find_packages(),
  install_requires = ['ScientificPython'],
  dependency_links = ["https://sourcesup.cru.fr/frs/?group_id=180&release_id=1351#stable-releases-2-8-title-content"])

当我运行python setup.py install时，这是输出的重要部分：

也许有一个问题是，虽然PyPI无法访问ScientificPython，或者easy_install ScentificPython至少无法下载，但No local packages or download links found for ScentificPython会失败。

为了使用setuptools安装ScientificPython，我需要做什么？

Answer 1

您是否尝试将直接下载链接（https://sourcesup.cru.fr/frs/download.php/2309/ScientificPython-2.8.tar.gz）放入dependency_links而不是html页面，因为您的脚本似乎找不到该包，然后尝试安装None。

编辑：刚注意到：python显然无法打开https资源 - 尝试在没有https的情况下上传它，使用普通的http

编辑2：你为什么不把整个ScientificPython文件夹放到你的发行文件夹中，并确保你的setup.py调用它的setup.py（或你需要调用的任何其他内容）？

Answer 2

问题在于它试图与https站点建立http连接。据我所知，setuptools不支持与https的连接。您将不得不使用另一种方法来获取这些包。

我的建议，如果你想使用setuptools，那么你在README中详细说明了他们必须下载该依赖项并安装它的文件，然后在setuptools中具有依赖性，如果他们不这样做则无法安装拥有它。

Answer 3

使用easy_install安装MyProxyClient时出现类似错误：

“下载错误：未知网址类型：https - 可能找不到某些软件包！”

以及有关未找到openssl标头的其他错误。

所以安装libssl-dev（在Ubuntu上）为我解决了这个问题！

Answer 4

Python无法处理https协议，安装openssl-devel包并重新安装python来修复此问题。

安装ScientificPython作为依赖项
