用于pygraphviz的conda-forge PackagesNotFoundError

Question

我正在尝试安装pygraphviz，但conda在通道中找不到它。下面是我得到的错误。Conda-forge已经在频道列表中，我尝试使用-c conda-forge，但仍然不起作用。我也尝试了bioconda通道，但不起作用。

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

PackagesNotFoundError: The following packages are not available from current channels:

  - pygraphviz

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

这里有什么问题吗？还是我遗漏了什么？

Answer 1

您正在从错误的通道安装它。执行以下操作：

conda install -c conda-forge pygraphviz

更新: Windows

在windows上安装pygraphviz似乎存在一些挑战。假设安装了graphiz并将其添加到Path中，Path是一个单独程序(不是python库)，这些解决方案可能会工作

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