Anaconda作为一个工具包集成管理工具，下载python工具包是很方便的，直接敲：

conda install package_name

但是有时候安装一个工具包（如wordcloud）的时候，在当前的channels中找不到这个包，会提示：

PackageNotFoundError: Packages missing in current channels:
  - wordcloud
We have searched for the packages in the following channels:

  - https://repo.continuum.io/pkgs/main/linux-64
  - https://repo.continuum.io/pkgs/main/noarch
  - https://repo.continuum.io/pkgs/free/linux-64
  - https://repo.continuum.io/pkgs/free/noarch
  - https://repo.continuum.io/pkgs/r/linux-64
  - https://repo.continuum.io/pkgs/r/noarch
  - https://repo.continuum.io/pkgs/pro/linux-64
  - https://repo.continuum.io/pkgs/pro/noarch

这个时候，我们可以使用下面的指令来查找我们想要安装的包（以wordcloud为例）

$ anaconda search -t conda wordcloud

(python36) C:\Users\zbb>anaconda search -t conda wordcloud
