When put Github-address, and the address has not Issue page

Some Github-project have not Issue page.
It make a trouble that can not collect any data from Issue page, because the program parses issue page from Github URL.

### example

# How about let user select the solution In command line?(yes or no)

## First solution

After Git-clone, parse the repository.

## Second solution

Stop parsing the project and announce It, when the program is finished.
