【问题描述】：

我最近切换到 Anaconda Python 发行版，我正在尝试掌握一些事情的窍门。我想安装this yaml-related package，由于还没有 conda 配方，我尝试了

conda pipbuild layered-yaml-attrdict-config

导致以下输出（我删除了系统路径的不相关条目）：

C:\Anaconda>

我不确定发生了什么，因为我不知道它在寻找什么文件，而且我对 conda 食谱一无所知，除非它们应该很棒并且不会出现这些错误。

我希望通过 conda 安装，以便一切都可以由 conda 管理，而不是由 pip 管理。

深入研究main_pipbuild.py 源代码，它似乎正在尝试运行C:\Anaconda\envs\_pipbuild_\bin\pip install package==version（使用适当的包和版本）。当我查看我的 C:\Anaconda\envs_pipbuild_ 时，没有 bin 文件夹，所以我猜 pip 没有正确安装到 pipbuild 环境中。之前关于没有“补丁”的警告也可能是个问题……

在使用conda install patch 安装patch 后，我再次尝试，结果如下：

所以它可能在Solving package specifications: .69 unparsed bytes left at the end of stream 处发现了包的某种问题。然后它做了这个显然失败的补丁。然后它尝试执行pip install 并再次在 pipbuild 环境中找不到 bin/pip 目录。

它应该在C:\Anaconda\envs\_pipbuild_\Scripts\pip.exe 寻找点子吗？因为那确实存在。

如果这是一个错误，请在此处报告：https://github.com/conda/conda-build/issues。我会等待反馈再做更多。

任何帮助都会很棒！

【解决方案1】：

我在尝试使用“conda pipbuild package-name”构建 PyPI 包时遇到了类似的问题，但我无法让它在 Windows 7 (x64) 上运行。我发现的一种有用的解决方法（如果您想使用“conda install package-name”将软件包安装到特定的 conda 环境中）如下：

使用“pip install package-name”安装 PyPI 包
使用“binstar upload %conda_install_path%/pkgs/package-name-ver-py27.tar.bz2”将包上传到您的 binstar 帐户
使用“conda install -c https://conda.binstar.org/user-name package-name -p %path-to-conda-env%”将包安装到特定的 conda env 中

【解决方案2】：

在https://groups.google.com/a/continuum.io/d/msg/anaconda/6_reeaIjx5c/fhRjbA4AdQkJ 上针对 Python 3 上的相同问题进行了修复。它涉及编辑 Python 标准库中的 distutils\cygwinccompiler.py 文件。

我认为你可以在 Python 2 中做同样的事情，尽管它可能需要一些翻译，因为 Python 2 版本的 cygwinccompiler 使用 os.popen 而不是 subprocess.check_output。假设您可以在文件的相关位置使用subprocess.check_output(['gcc', '-dumpmachine'], shell=True)，它将解决问题。
