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. r= z.pyz1Not a URL, existing file, or requirement spec: %rrW N)r� r r� � _download_urlrP rK r4 � gen_setupr[ rG r� �parser� r r� �fetch_distribution)r� �spec�tmpdirrE �foundr7 rJ r: r: r; r> � s" zPackageIndex.downloadc sN � j d | � i � d } d � � � � f d d � } | rf � j � � j | � | | � } n | d k r� | p� | | | � } n | d k r� � j d k r� � j � | | � } n | d k r� | r� � j | � | | � } n | d k r� j d � rd pd | � n/ � j d | � | j d � j | 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. Unless the `develop_ok` flag is set, development and system eggs (i.e., those using the ``.egg-info`` format) will be ignored. zSearching for %sNc s� | d k r � } n x� | | j D]q } | j t k rn � rn | � k r# � j d | � d � | <q# q# n | | k r# | j t k s� � r# | Sq# Wd S)Nz&Skipping development or system egg: %sr= )rj rL r r� r )�req�envrR )� develop_okr� �skipped�sourcer: r; r 1 s "z-PackageIndex.fetch_distribution.<locals>.findz2No local packages or download links found for %s%sza source distribution of r� zBest match: %srW )r� r� r� r� r� �cloner> rW ) r� r� r � force_scanr r Z local_indexrR r r: )r r� r r r; r s. z PackageIndex.fetch_distributionc C s/ | j | | | | � } | d k r+ | j Sd S)a3 Obtain a file suitable for fulfilling `requirement` DEPRECATED; use the ``fetch_distribution()`` method now instead.
