与WindowsError一起失败找不到文件

Question

最近，我转向了Anaconda发行版，我正在尝试了解问题的诀窍。我想安装这个与yaml相关的软件包，因为还没有conda的配方，所以我试了一下

conda pipbuild layered-yaml-attrdict-config

这导致了以下输出(我删除了系统路径中的无关条目)：

C:\Anaconda>conda install layered-yaml-attrdict-config

我不知道发生了什么，因为我不知道它在寻找什么文件，我还不知道任何关于conda食谱的信息，只是它们应该是很棒的，而且不会出现这样的错误。

我希望通过conda安装，这样一切都可以由conda来管理，而不是由pip来管理一些东西。

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

在用patch安装conda install patch之后，我再次尝试，结果如下：

因此，它发现了包的一些问题，也许是在Solving package specifications: .69 unparsed bytes left at the end of stream。然后它做这个补丁的事情，显然是失败的。然后尝试执行pip install，然后在pipbuild环境中再次找不到bin/pip目录。

它应该是在C:\Anaconda\envs\_pipbuild_\Scripts\pip.exe寻找pip吗？因为那是存在的。

如果这是一个bug，下面是报告它的位置：https://github.com/conda/conda-build/issues。我会等待反馈，然后再做。

任何帮助都会很好！

Answer 1

在reeaIjx5c/fhRjbA4AdQkJ上的Python3上有一个相同问题的修复程序。它涉及到编辑Python库中的distutils\cygwinccompiler.py文件。

我认为您可以在Python2中做同样的事情，尽管它可能需要一些翻译，因为Python2版本的cygwinc编译器使用os.popen而不是subprocess.check_output。因此，您只需在文件的相关位置使用subprocess.check_output(['gcc', '-dumpmachine'], shell=True)，就可以解决这个问题。

Answer 2

在尝试用“name”构建PyPI包时，我也遇到过类似的问题，而且我无法在Windows7 (x64)上运行它。我发现的一个有用的解决方法(如果您想安装带有“”的包，可以安装到特定的conda环境中)如下：

• 用"pip安装包名称“安装PyPI包
• 使用"binstar上载%conda_install_path%/pkgs/package-name-ver-py27.tar.bz2“”将包上载到binstar帐户
• 使用"conda Install -c https://conda.binstar.org/user-name包-name -p %path- conda - env %“将软件包安装到特定的conda env中。
