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 Author: aliyun-developers-efficiency Author-email: aliyun-developers-efficiency@list.alibaba-inc.com License: UNKNOWN Location: /home/phpor/.local/lib/python2.7/site-packages Requires: colorama, jmespath

      1 2 3 4 5 6 7 8 9 10

      # 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 Author: aliyun-developers-efficiency Author-email: aliyun-developers-efficiency@list.alibaba-inc.com License: UNKNOWN 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 Author: aliyun-developers-efficiency Author-email: aliyun-developers-efficiency@list.alibaba-inc.com License: UNKNOWN Location: /home/phpor/.local/lib/python2.7/site-packages Requires: colorama, jmespath Files: ../../../bin/aliyun_completer ../../../bin/aliyun_zsh_complete.sh ../../../bin/aliyuncli ...

      1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

      $ 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 Author: aliyun-developers-efficiency Author-email: aliyun-developers-efficiency@list.alibaba-inc.com License: UNKNOWN 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
