将 ScientificPython 作为依赖项安装

Question

我试图在我的setup.py 中将ScientificPython 列为依赖项。但是，在安装过程中，python似乎找不到包。我的方法有什么问题？

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"])

这是我运行python setup.py install时输出的重要部分：

也许一个问题是，ScientificPython 在某种程度上无法通过PyPI 访问，或者至少无法下载，因为easy_install ScentificPython 将因No local packages or download links found for ScentificPython 而失败。

要使用 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包，然后尝试安装 None。

编辑：刚刚注意到：python 显然无法打开 https 资源 - 尝试使用普通 http 在没有 https 的地方上传它

编辑 2：为什么不将整个 ScientificPython 文件夹放入分发文件夹并确保 setup.py 调用它的 setup.py（或您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 不支持到 https 的连接。您将不得不使用另一种方法来获取这些包。

如果您想使用 setuptools，我的建议是您在 README 中详细说明他们必须下载该依赖项并安装它的文件，然后在 setuptools 中安装依赖项，如果他们不这样做，则安装失败'没有。

Answer 3

Python 无法处理 https 协议，安装 openssl-devel 包并重新安装 python 以解决此问题。

Answer 4

我在使用 easy_install 安装 MyProxyClient 时遇到了类似的错误：

“下载错误：未知url类型：https--某些包可能找不到！”

以及其他关于找不到 openssl 标头的错误。

所以安装libssl-dev（在 Ubuntu 上）为我解决了这个问题！
