一、问题

conda的其他命令没问题，比如conda env list命令是可以照常运行的，但是运行

conda create --name 环境名

命令会报出以下错误：

二、解决方法

借鉴：http://events.jianshu.io/p/f53d93ad63c3

根据错误提示，json文件解读出错。什么json文件呢？我猜是conda的配置文件C:\Users\DELL\.condarc，因为我之前改过conda的配置文件，所以猜测是这里出的问题。

本来想的是，直接搜一下.condarc文件的默认内容粘上去，但是这样就没有镜像的配置了。所以我没用默认的.condarc文件，而是搜了一段配置了清华源镜像的

channels:- defaults
show_channel_urls: true
channel_alias: https://mirrors.tuna.tsinghua.edu.cn/anaconda
default_channels:- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloudmsys2: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloudbioconda: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloudmenpo: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloudpytorch: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloudsimpleitk: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
ssl_verify: true

更改完成后，在命令行输入以下命令完成配置的更新：

conda config --set show_channel_urls yes
