当我尝试安装软件包时，我看到来自conda的奇怪错误。仅仅搜索包裹会产生如下奇怪的警告。这是怎么回事？
(base) $ conda search libdvid-cpp

Conda无法读取远程软件包存储库。以下是一些尝试：
入住~/.condarc或.../miniconda/.condarc。或使用以下命令查看配置文件的位置：
conda config --show-sources
确保所有通道名称拼写正确。
anaconda.org的令牌anaconda logout
anaconda login
（如果您没有安装anaconda命令，则此问题不适用于您。）
在Mac上：
sudo killall -HUP mDNSResponder
在Linux上，您的DNS条目可能根本不会被缓存，但请参阅此处：
