** Description changed: [impact] pip 8.1.1 (xenial) tries to access properties that were dropped from the Requirement class and when pip's code tries to access Requirement.project_name fails, this was fixed in 8.1.2. Any user trying to install a package that triggers the pkg_resources.VersionConflict exception during will get the error "AttributeError: 'Requirement' object has no attribute 'project_name'" [Test Case] # wget https://pypi.python.org/packages/49/6f/183063f01aae1e025cf0130772b55848750a2f3a89bfa11b385b35d7329d/requests-2.10.0.tar.gz # wget https://pypi.python.org/packages/2e/ad/e627446492cc374c284e82381215dcd9a0a87c4f6e90e9789afefe6da0ad/requests-2.11.1.tar.gz # pip install requests-2.10.0.tar.gz # pip install requests-2.11.1.tar.gz Expected result: pip installs requests 2.11.1 Actual result: pip fails with the following exception root@pip-x:/home/ubuntu# pip install requests-2.11.1.tar.gz Processing ./requests-2.11.1.tar.gz Exception: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 209, in main status = self.run(options, args) File "/usr/lib/python2.7/dist-packages/pip/commands/install.py", line 328, in run wb.build(autobuilding=True) File "/usr/lib/python2.7/dist-packages/pip/wheel.py", line 748, in build self.requirement_set.prepare_files(self.finder) File "/usr/lib/python2.7/dist-packages/pip/req/req_set.py", line 360, in prepare_files ignore_dependencies=self.ignore_dependencies)) File "/usr/lib/python2.7/dist-packages/pip/req/req_set.py", line 600, in _prepare_file req_to_install.check_if_exists() File "/usr/lib/python2.7/dist-packages/pip/req/req_install.py", line 1011, in check_if_exists self.req.project_name AttributeError: 'Requirement' object has no attribute 'project_name' You are using pip version 8.1.1, however version 8.1.2 is available. You should consider upgrading via the 'pip install --upgrade pip' command. [Regression Potential] * None, this change is already part of 8.1.2, and most of the change is already part of the ubuntu package, there is just one last place where the code is accessing Requirement.project_name [Other info] From 8e236dd6a09bd2f70f9d4fc886da8c354d4c58f2 Mon Sep 17 00:00:00 2001 From: Donald Stufft <don...@stufft.io> Date: Wed, 11 Nov 2015 18:51:46 -0500 Subject: [PATCH] Update to use the Requirement class from packaging https://github.com/pypa/pip/commit/8e236dd6a09bd2f70f9d4fc886da8c354d4c58f2 + + This SRU fixes autopkgtest, so the building process to get into + -proposed doesn't block it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1626258 Title: [SRU] AttributeError: 'Requirement' object has no attribute 'project_name' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-pip/+bug/1626258/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
