https://docs.snapcraft.io/the-python-plugin/8529 says "Path to a requirements.txt file". Relative to what? I'm getting: Failed to find the referred requirements file at the given path: 'requirements.txt'. Check the property and ensure the file exists. This is unhelpful because it isn't telling me where it's looking, requiring me to guess by trying various base paths. To fix this, please: 1. Document what the path should be relative to. 2. Arrange for the error message to tell me where it actually looked. This is particularly important for snapcraft, IMHO, as depending on what's going on various different base paths are used. This was with snapcraft 2.43.1 on Xenial.
