Conda构建由于msgpack依赖关系而失败(旧名称-msgpack-python问题)

Question

我正在尝试构建一个依赖于依赖于conda的pip库(分布式)的Python包。我一直收到在setuptools中下载被禁用的错误，但是我在我的依赖项中列出了msgpack (或者msgpack-python，我尝试了两者)。我相信这是因为皮普的名字改变了。

旧的名字是msgpack-python，新的名字是msgpack。

distributed将msgpack作为依赖项列出，但看起来conda将msgpack-python安装为conda包(https://anaconda.org/anaconda/msgpack-python)。然后它抱怨说setuptools需要msgpack，不能下载。

是否需要将Anaconda上的名称更改为msgpack？

这是我正在犯的错误：

Answer 1

通过将构建命令中的参数更改为pip，我能够使其工作如下：

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

键标志为--no-deps。我显式地告诉conda在meta.yaml文件中安装meta.yaml(package包)，然后以后的pip安装不会检查msgpack依赖项(我认为这个依赖项会失败，因为它只看到msgpack-python而不是msgpack)。
