问题描述
操作系统：Ubuntu 20.04LTS 应用：Miniconda3 目标：使用Conda创建一个新环境并安装两个特定的库 正在安装的库：conda-forge频道中的 libmumps 和 fenics
当前结果：conda创建了环境，但是由于以下一系列错误而无法安装该库。从错误中我了解到这与JSON有关。我已经搜索过，但是没有找到适合我的解决方案。
(fenics) blueskies@sz-HP15-Nb:~$ conda install fenics

Solving environment: Failed with initial frozen solve. retrying with flexible solve.
Solving environment: Failed with repodata from current_repodata.json,will retry with next repodata source.
