Question

I am trying to run this script: https://github.com/Lab41/hermes/blob/master/src/utils/code_etl/repo_to_json.py

on a local copy of matplotlib. But I keep receiving this error message that I don't understand. I've trying running it in command prompt in administrator mode but still get the error.

 Traceback (most recent call last):
  File "C:/Users/daman/Desktop/hermes-master/src/utils/code_etl    /repo_to_json.py", line 211, in <module>
repo_name
  File "C:/Users/daman/Desktop/hermes-master/src/utils/code_etl/repo_to_json.py", line 130, in process_local_repo
output_file = output_dir + "/" + repo_name.replace('/', '_') + ".json"
TypeError: a bytes-like object is required, not 'str'

During handling of the above exception, another exception occurred:

Answer 1

The failure to clean up the temporary repository may be due to some other part of the code still having the Git object file in question open (which, on Windows, prevents deletion). But the important bit is that this code is written for Python 2 and isn't compatible with the 3 you're using. (Other parts use print statements and wouldn't even compile.)
