#138

I also encountered the same issue.

My current computer is following envrionment.
Machine: M1 Macbook Air
OS: macOS Monterey 12.6
Python: 3.10.6

$ python migrate.py -bu katsusuke "my-organization/my-repo" "my-organization/myrepo" katsusuke
Traceback (most recent call last):
  File "/Users/katsusuke/git/github.com/jeffwidman/bitbucket-issue-migration/migrate.py", line 897, in <module>
    sys.exit(main(options))
  File "/Users/katsusuke/git/github.com/jeffwidman/bitbucket-issue-migration/migrate.py", line 142, in main
    users_bb_gh_mapping = [line.rstrip() for line in open(''.join(options._map_users), "r")]
FileNotFoundError: [Errno 2] No such file or directory: ''

python --version
Python 3.10.6

I think open('') throws FileNotFoundError.

$ python

>>> open("")

I tried it on Linux, but open function have the same behavior.
