Anaconda无奈装置一些包的问题

anaconda Collecting package metadata (current_repodata.json): failed

具体报错信息为

(env_name) [root@host anaconda3]# conda install python==3.6.2Collecting package metadata (current_repodata.json): failed# >>>>>>>>>>>>>>>>>>>>>> ERROR REPORT <<<<<<<<<<<<<<<<<<<<<<    Traceback (most recent call last):    '''    此处略去    '''        raise Response304ContentUnchanged()    conda.core.subdir_data.Response304ContentUnchanged    During handling of the above exception, another exception occurred:    '''    此处略去    '''    json.decoder.JSONDecodeError: Expecting ':' delimiter: line 46906 column 14 (char 1474212)`$ /root/anaconda3/bin/conda install python==3.6.2`

解决办法：
运行 conda clean -i 革除索引缓存即可，亲测无效
