python - pygraphviz 的 conda-forge PackagesNotFoundError

问题描述

我正在尝试安装pygraphviz，但 conda 在频道中找不到它。以下是我得到的错误。Conda-forge已经在频道列表中，我尝试过-c conda-forge但仍然无法正常工作。我也尝试过bioconda频道，但没有奏效。

> conda install -c anaconda pygraphviz
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Pygraphviz根据文档，应该在bioconda和conda - forge中，但我仍然找不到包。我也更新了 conda conda update conda，但仍然没有运气。

这里有什么问题吗？还是我想念的东西？

解决方案

您从错误的渠道安装它。做：

conda install -c conda-forge pygraphviz

更新：Windows

在 Windows 上安装 pygraphviz 似乎存在挑战。假设 graphiz 已安装并添加到 Path 中，这是一个单独的程序（不是 python 库），这些解决方案可能有效

# Tom Hanks’ answer 
conda install graphviz pygraphviz -c alubbock

请参阅 SO 答案在 Windows 上安装 Pygraphviz
