the usage commands :

  • case 1: ag is not found
  • case 2: Ag command ‘ag’ was not found. Is the silver searcher installed and on your $PATH?

  solution：
  step 1: plug ag in the vim-plug (for error case 1)
  step 2: ubuntu 中 install silersearcher-ag (for error case 2)

just install the python-mode for vim

next steps:
