python - 由于 msgpack 依赖性，Conda 构建失败(旧名称问题 - msgpack-python)

Question

我正在尝试构建一个依赖于 pip 库(分布式)的 Python conda 包，而 pip 库又依赖于 msgpack。我一直收到在 setuptools 中下载被禁用的错误，但我列出了 msgpack(或 msgpack-python，我都试过了)在我的依赖项中。我相信这是由于 pip 上的名称更改所致。

旧名称是 msgpack-python，新名称是 msgpack。

distributed 将 msgpack 列为依赖项，但看起来 conda 将 msgpack-python 安装为 conda包(https://anaconda.org/anaconda/msgpack-python)。然后它提示 setuptools 需要 msgpack 并且无法下载。

会不会是Anaconda上的名字需要改成msgpack？

这是我遇到的错误:

Answer 1

我能够通过将构建命令中的 pip 参数更改为此来使其工作:

python -m pip install --no-deps --ignore-installed 。

关键标志是--no-deps。我明确告诉conda在meta.yaml文件中安装msgpack-python(wa conda package)，然后后面的pip安装不检查msgpack 依赖项(我认为它失败了，因为它只看到 msgpack-python，而不是 msgpack)
