If it is the URL of a .py file with an unambiguous ``#egg=name-version`` tag (i.e., one that escapes ``-`` as ``_`` throughout), a trivial ``setup.py`` is automatically created alongside the downloaded file. If `spec` is a ``Requirement`` object or a string containing a project/version requirement spec, this method returns the location of a matching distribution (possibly after downloading it to `tmpdir`). If `spec` is a locally existing file or directory name, it is simply returned unchanged. If `spec` is a URL, it is downloaded to a subpath of `tmpdir`, and the local filename is returned. Various errors may be raised if a problem occurs during downloading. r8 z.pyrU N)r� r r� � _download_urlrN rI r1 � gen_setuprY rE r� r' r� �fetch_distribution)r� r$ �tmpdirrC �foundr4 rH r% r% r& r9 s zPackageIndex.downloadc s: � j d | � i � d } d � � � � � f d d � } | rf � j � � j | � | | � } | r� | d k r� | | | � } | d k r� � j d k r� � j � | | � } | d k r� | r� � j | � | | � } | d k r� j d � rd p d | � n# � j d | � | j d | j � Sd S) a| Obtain a distribution suitable for fulfilling `requirement` `requirement` must be a ``pkg_resources.Requirement`` instance. If necessary, or if the `force_scan` flag is set, the requirement is searched for in the (online) package index as well as the locally installed packages. If a distribution matching `requirement` is found, the returned distribution's ``location`` is the value you would have gotten from calling the ``download()`` method with the matching distribution's URL or filename. If no matching distribution is found, ``None`` is returned. If the `source` flag is set, only source distributions and source checkout links will be considered.
