An unexpected error has occurred. Conda has prepared the above report.

If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers?

[y/N]: n

No report sent. To permanently opt-out, use

    $ conda config --set report_errors false

可以看到报错是显示HTTP请求404，应该是镜像源的问题。
HTTPError: 404 Client Error: Not Found for url: https://mirrors.bfsu.edu.cn/anaconda/cloud/menpo/noarch/current_repodata.json

恢复一下默认源试试：
conda config --remove-key channels
查看现在源：
conda config --show channels

channels:
  - defaults

没问题，然后再尝试安装包，
