Initialize a new resolver using the default backend doing real requests.
Reads the flat index entries.
§Marker environment
The marker environment is optional.
When a marker environment is not provided, the resolver is said to be in “universal” mode. When in universal mode, the resolution produced may contain multiple versions of the same package. And thus, in order to use the resulting resolution, there must be a “universal”-aware reader of the resolution that knows to exclude distributions that can’t be used in the current environment.
When a marker environment is provided, the resolver is in
“non-universal” mode, which corresponds to standard pip behavior that
works only for a specific marker environment.
