成功解决anaconda下安装报错：PackagesNotFoundError: The following packages are not available from current chann

解决anaconda下安装包时报错：PackagesNotFoundError: The following packages are not available from current channels

以安装icecream包为例

输入conda install icecream安装时，显式报错.

那么我们就查询包所存在的版本，输入如下命令：

anaconda search -t conda icecream

然后会出现很多信心，选择自己需要的安装包

根据需求选择自己要安装包的版本，输入以下命令查看安装渠道

anaconda show conda-forge/icecream

根据提示命令进行安装

conda install --channel https://conda.anaconda.org/conda-forge icecream
