pip安装后未找到cget

我安装 cget this guide 使用:

pip install cget

终端显示:

Collecting cget

cget install curl

它抱怨道:

Command 'cget' not found, did you mean:

  command 'mget' from snap mget (0.1.2)
  command 'cset' from deb cpuset
  command 'cgpt' from deb cgpt
  command 'cfget' from deb cfget
  command 'wget' from deb wget
