使用conda install和conda create命令会出现下面的问题：

Collecting package metadata (current_repodata.json): failed

Collecting package metadata (current_repodata.json): failed>>>>>>>>>>>>>>>>>>>>>> ERROR REPORT <<<<<<<<<<<<<<<<<<<<<<Traceback (most recent call last):File "D:\Anaconda3\lib\site-packages\conda\exceptions.py", line 1079, in __call__return func(*args, **kwargs)File "D:\Anaconda3\lib\site-packages\conda\cli\main.py", line 84, in _mainexit_code = do_call(args, p)File "D:\Anaconda3\lib\site-packages\conda\cli\conda_argparse.py", line 82, in do_callreturn getattr(module, func_name)(args, parser)File "D:\Anaconda3\lib\site-packages\conda\cli\main_install.py", line 20, in executeinstall(args, parser, 'install')

解决办法：

conda config --show-sources

找到.condarc文件位置并删除。
