1. pip install aliyuncli 后发现依然没有aliyuncli命令
   1. 查看aliyuncli安装到哪里了
      

      # pip show -f aliyuncli
      Name: aliyuncli
      Version: 2.1.9
      Summary: Universal Command Line Environment for aliyun
      Home-page: http://docs.aliyun.com/?spm=5176.1829009.1002.1.LxlLfS#/pub/aliyun-command-line-interface

      Location: /home/phpor/.local/lib/python2.7/site-packages
      Requires: colorama, jmespath
      

   2.  查看安装包中有没有aliyuncli这个命令（肯定是有的）
      

      $ pip show -f aliyuncli
      Name: aliyuncli
      Version: 2.1.9
      Summary: Universal Command Line Environment for aliyun
      Home-page: http://docs.aliyun.com/?spm=5176.1829009.1002.1.LxlLfS#/pub/aliyun-command-line-interface

      Location: /home/phpor/.local/lib/python2.7/site-packages
      Requires: colorama, jmespath
      Files:
        ../../../bin/aliyun_completer
        ../../../bin/aliyun_zsh_complete.sh
        ../../../bin/aliyuncli
      ...
      

   3. 基本可知，aliyuncli相关命令安装在了 /home/phpor/.local/bin 下面，该路径应该没有在$PATH中，添加到$PATH就行了
   4. Done
