CondaHTTPError: HTTP 404 NOT FOUND for url https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/noarch/repodata.json
Elapsed: 00:00.395932

The remote server could not find the noarch directory for the
requested channel with url: https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free

As of conda 4.3, a valid channel must contain a noarch/repodata.json and
associated noarch/repodata.json.bz2 file, even if noarch/repodata.json is
empty. please request that the channel administrator create
noarch/repodata.json and associated noarch/repodata.json.bz2 files.
$ mkdir noarch
$ echo ‘{}’ > noarch/repodata.json
$ bzip2 -k noarch/repodata.json

You will need to adjust your conda configuration to proceed.
Use conda config --show channels to view your configuration’s current state.
Further configuration help can be found at https://conda.io/docs/config.html.

怎么解决？？？？
