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：
C:\\Users\\DELL>conda create -n recsys

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

show_channel_urls: 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
