Why is pip not installing the LATEST? Is there a way to force LATEST?

$ sudo pip install --upgrade pefile Requirement already up-to-date: pefile in /usr/local/lib/python2.7/dist-packages Cleaning up... $ pip show pefile --- Name: pefile Version: 1.2.10-114 Location: /usr/local/lib/python2.7/dist-packages Requires: $ pip search "pefile" pefile - Python PE parsing module INSTALLED: 1.2.10-114 LATEST: 1.2.10-139 $ sudo pip install --upgrade --force-reinstall --pre pefile Downloading/unpacking pefile Downloading pefile-1.2.10-114.tar.gz (49kB): 49kB downloaded Running setup.py (path:/tmp/pip_build_root/pefile/setup.py) egg_info for package pefile Installing collected packages: pefile Found existing installation: pefile 1.2.10-114 Uninstalling pefile: Successfully uninstalled pefile Running setup.py install for pefile Successfully installed pefile Cleaning up...

If you look at the pefile pages for 1.2.10-114 and 1.2.10-139 - you'll see an important difference, the latter doesn't have a "Files" section with a source and egg. That means that the files are hosted externally and you need to allow pip to install from an external and unverified source:

pip install pefile --upgrade --allow-external=pefile --allow-unverified=pefile

Demo:

$ pip show pefile --- Name: pefile Version: 1.2.10-114 $ pip install pefile --upgrade --allow-external=pefile --allow-unverified=pefile pefile an externally hosted file and may be unreliable pefile is potentially insecure and unverifiable. ...
