创建conda环境:“发现冲突！"解决环境和“查找最短冲突路径"时；永远跑 [英] Create conda environment: "Found conflicts!" when solving environment and "Finding shortest conflict path" running forever
本文介绍了创建conda环境:“发现冲突！"解决环境和“查找最短冲突路径"时；永远跑的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
为我提供了一个environment.ubuntu.yml文件，以便能够创建conda环境.但是，运行conda create env --file environment.ubuntu.yml，我得到以下输出:
I was provided with an environment.ubuntu.yml file to be able to create a conda environment. However, running conda create env --file environment.ubuntu.yml I get the following output:
conda env create --file environment.ubuntu.yml
Collecting package metadata (repodata.json): done

Finding shortest conflict path持续了很长时间-显然，它正在尝试解决某些依赖性问题.运行了两个小时，目前尚不清楚它是否会停止.
The Finding shortest conflict path goes on for a long time - apparently it is trying to resolve some dependency issues. Running for 2 hours it is not clear if it will ever stop.
我的问题是:这是怎么回事，我可以以某种方式手动加快此过程吗，例如通过删除不必要的依赖关系?由于我没有创建环境，因此我不知道实际需要哪些环境.
My question is: what is happening here and can I somehow manually speed up this process, e.g. by removing unnecessary dependencies? Since I did not create the environment I don't know which are actually necessary.
我好奇的原因是，当dependencies中的一个是2.13.1并且我已经通过2.13.1
The reason why I'm curious is because it is checking conflict paths like fontconfig[version='>=2.12.6,<3.0a0'] when the one in dependencies is 2.13.1 and I have installed it through 2.13.1

推荐答案
此错误和随后的行为很可能来自 Anaconda错误，该错误有时会导致本地环境不一致.到2020年1月26日为止，该错误尚未解决.
This error and the subsequent behaviour is very likely coming from the Anaconda bug which from time to time causes inconsistencies in the local environment. As of Jan 26th, 2020 the bug was not yet resolved.
对我来说，同样的问题在Mac上也很明显.
For me the same problem manifests profoundly on Mac.
