我正在尝试构建一个Python conda程序包，该程序包依赖于一个依赖于msgpack的pip库（分布式）。我一直收到错误消息，说setuptools的下载被禁用，但是我的依赖项中列出了msgpack（或msgpack-python，我都尝试过）。我相信这是由于pip上的名称更改。
旧名称为msgpack-python，新名称为msgpack。
distributed将msgpack列为依赖项，但看起来conda安装了msgpack-python作为conda软件包（https://anaconda.org/anaconda/msgpack-python）。然后，它抱怨setuptools要求msgpack，并且无法下载。
是否可能需要在Anaconda上将名称更改为msgpack？
这是我得到的错误：

RuntimeError: Setuptools downloading is disabled in conda build. Be sure to add all dependencies in the meta.yaml url=https://pypi.org/simple/msgpack/
答案 0 :(得分：0)
通过将build命令中pip的参数更改为此，我能够使它起作用：
python -m pip install --no-deps --ignore-installed .
键标志为--no-deps。我明确告诉conda在msgpack-python文件中安装meta.yaml（wa conda软件包），然后以后的pip安装不检查msgpack依赖项（我认为失败是因为它仅看到msgpack-python，而不是msgpack）
