我们一般安装第三方包（pulp）会通过cmd命令： conda install pulp
但是今天安装pulp包的时候出现下面的问题：
C:\Users\81584>conda install pulp
Fetching package metadata .............
PackageNotFoundError: Packages missing in current channels:
- pulp
We have searched for the packages in the following channels:
- https://repo.continuum.io/pkgs/main/win-64

一开始我没找到解决方法，上网查阅之后可以按照以下方法进行：
（1）、执行 anaconda search -t conda pulp
出现如下东西：
C:\Users\81584>anaconda search -t conda pulp
