在pyenv下使用anaconda环境下更新python 时出错

conda install python=3.6
Solving environment: failed

CondaHTTPError: HTTP 404 NOT FOUND for url https://conda.anaconda.org/conda-virtualenvwrapper/noarch/repodata.json

The remote server could not find the noarch directory for the
requested channel with url: https://conda.anaconda.org/conda-virtualenvwrapper

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.

上面这个问题出现了很久，终于勉强解决了，我时直接恢复默认源就解决了
1.输入conda config --show channels

2.输入conda config --remove-key channels，这个命令是恢复默认源
之后再查看，输入conda config --show channels，发现channels只剩

再输入conda install python=3.6(我是安装Python3.6版本的）<然后成功下载。不能保证每个人情况一样，我的可以了。
