pip:缺少分发规范.如何解决这个问题？

Question

我在虚拟机上运行此命令时出现以下错误:

$ sudo pip install -U -v --no-deps -b /tmp/piyush/ /tmp/piyush/common_bundle

  File "/usr/local/lib/python2.7/dist-packages/pip-6.0.6-py2.7.egg/pip/_vendor/pkg_resources/__init__.py", line 2807, in parse_requirements
    raise ValueError("Missing distribution spec", line)
ValueError: ('Missing distribution spec', '/tmp/piyush/common_bundle')

我的输入文件是存档.

$ file common_bundle
common_bundle: Zip archive data, at least v2.0 to extract

pip的版本是:

$ pip -V
pip 6.0.6 from /usr/local/lib/python2.7/dist-packages/pip-6.0.6-py2.7.egg (python 2.7)

这是common_bundle中的pip清单:

# This is a pip bundle file, that contains many source packages
# that can be installed as a group.  You can install this like:
#     pip this_file.zip
# The rest of the file contains a list of all the packages included:
PyYAML==3.10
boto==2.6.0
msgpack-python==0.2.2
tornado==2.1.1
ujson==1.22
virtualenv==1.8.2
bottle==0.10.7
raven==2.0.3
protobuf==2.4.1
# These packages were installed to satisfy the above requirements:
simplejson==2.4.0
distribute==0.6.32

有什么看起来可疑吗？

谢谢.

从存档安装时pip，文件必须具有正确的扩展名，或者您需要显式使用file://协议。将文件重命名为/tmp/piyush/common_bundle.zip或使用file:///tmp/piyush/common_bundle.

您看到的错误与存档的内容无关，pip甚至还没有解压它。
