我在Windows 10上使用miniconda（有关conda info的输出，请参见下面的Edit 2）。我想使用PyPI软件包pypolymake。因此，我尝试按照here给出的说明使用conda框架构建conda包。在开始之前，我已经按照先决条件中的建议成功运行了conda install git conda-build。
在Anaconda Prompt中运行命令conda skeleton pypi pypolymake时，出现以下错误：
(base) C:\Users\Christoph>conda skeleton pypi pypolymake

You can install 'patch' using apt-get, yum (Linux), Xcode (MacOSX),
or conda, m2-patch (Windows),
所以，我的问题是：这个错误是从哪里来的，我该如何避免呢？
我还有第二个问题：在哪个conda环境中执行命令conda skeleton pypi pypolymake和conda-build pypolymake是否重要？我应该在base中这样做吗（因为我最终可能希望在不同的conda环境中使用pypolymake）？还是应该在要使用pypolymake的环境之一中执行此操作？还是我必须在要使用它的每个环境中构建该软件包？
在此先感谢您的帮助和建议！
编辑：
如注释中所建议，我已经尝试使用命令conda skeleton pypi --extra-specs patch pypolymake，但是获得了不同的错误消息：
(base) C:\Users\Christoph>conda skeleton pypi --extra-specs patch pypolymake
