修改这个文件：
~\Anaconda\pkgs\nb_conda-2.2.1-py38_1\Lib\site-packages\nb_conda,
查找这一句:

return {

    "environments": [root_env] + [get_info(env)

                                  for env in info['envs']]

}

改为

return {

    "environments": [root_env] + [get_info(env) for env in info['envs']

                                  if env != root_env['dir']]

}
