Elapsed: 00:00.270290
The remote server could not find the noarch directory for the
requested channel with url: https://mirrors.aliyun.com/pypi/simple
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.
