我已经创建了新环境
(jh2) [xxx@yyy~]$ conda env list
# conda environments:
#
base /opt/miniconda
jh2 * /opt/miniconda/envs/jh2
显然是空的
(jh2) [xxx@yyy~]$ conda list
# packages in environment at /opt/miniconda/envs/jh2:
#
# Name Version Build Channel
我在文件系统上有离线频道
(jh2) [xxx@yyy~]$ conda config --get channels
--add channels 'file://opt/repo/repository_conda-forge/jh_offline/' # lowest priority
但是当我尝试安装某些软件包时，它会失败。
(jh2) [xxx@yyy~]$ conda install jupyterhub=1.0.0 --offline

我不明白在空的环境中怎么会有冲突！
最重要的是。在可以访问互联网的机器上，完全安装了相同的软件包，没有任何问题。
例如尝试conda search tornado包装可用
# Name Version Build Channel
