Resolve dependencies for a pipenv project, acts as a portal to the target environment. Regardless of whether a virtual environment is present or not, this will spawn a subproces which is isolated to the target environment and which will perform dependency resolution. This function reads the output of that call and mutates the provided lockfile accordingly, returning nothing. :param List[:class:`~requirementslib.Requirement`] deps: A list of dependencies to resolve. :param Callable which: [description] :param project: The pipenv Project instance to use during resolution :param Optional[bool] pre: Whether to resolve pre-release candidates, defaults to False :param Optional[bool] clear: Whether to clear the cache during resolution, defaults to False :param Optional[bool] allow_global: Whether to use *sys.executable* as the python binary, defaults to False :param Optional[str] pypi_mirror: A URL to substitute any time *pypi.org* is encountered, defaults to None :param Optional[bool] dev: Whether to target *dev-packages* or not, defaults to False :param pipfile: A Pipfile section to operate on, defaults to None :type pipfile: Optional[Dict[str, Union[str, Dict[str, bool, List[str]]]]] :param Dict[str, Any] lockfile: A project lockfile to mutate, defaults to None :param bool keep_outdated: Whether to retain outdated dependencies and resolve with them in mind, defaults to False :raises RuntimeError: Raised on resolution failure :return: Nothing :rtype: None

It will either iterate over the `iterable` or `length` items (that are counted up). While iteration happens, this function will print a rendered progress bar to the given `file` (defaults to stdout) and will attempt to calculate remaining time and more. By default, this progress bar will not be rendered if the file is not a terminal. The context manager creates the progress bar. When the context manager is entered the progress bar is already displayed. With every iteration over the progress bar, the iterable passed to the bar is advanced and the bar is updated. When the context manager exits, a newline is printed and the progress bar is finalized on screen. No printing must happen or the progress bar will be unintentionally destroyed. Example usage:: with progressbar(items) as bar: for item in bar: do_something_with(item) Alternatively, if no iterable is specified, one can manually update the progress bar through the `update()` method instead of directly iterating over the progress bar.
