I have a proprietary module which includes a few console scripts having colons in the name, e.g: entry_points={ 'console_scripts': [ 'script:xy=mymodule.scripts.script:main', ... I noticed that pytest began to fail after adding the new scripts, and traced it to importlib_metadata. ``` File "/home/bailey/bart_rest_api/venv/lib/python3.7/site-packages/importlib_metadata/__init__.py", line 113, in _from_text config.read_string(text) File "/usr/lib/akamai-portable-python/lib/python3.7/configparser.py", line 722, in read_string self.read_file(sfile, source) File "/usr/lib/akamai-portable-python/lib/python3.7/configparser.py", line 717, in read_file self._read(f, source) File "/usr/lib/akamai-portable-python/lib/python3.7/configparser.py", line 1091, in _read fpname, lineno) configparser.DuplicateOptionError: While reading from '<string>' [line 44]: option 'script' in section 'console_scripts' already exists ``` I was able to resolve the problem by adjusting the construction of the config object in _from_text to: config = ConfigParser(delimiters=('='), strict=False) although I suspect there are other implications of changing that setting.
