Latest 'pip' fails with "requires setuptools >= 0.8 for dist-info"

Using the recent (1.5) version of pip, I get an error when attempting to update several packages. For example, sudo pip install -U pytz results in failure with: Wheel installs require setuptools >= 0.8 for dist-info support. pip's wheel support requires setuptools >= 0.8 for dist-info support. I don't understand this message (I have setuptools 2.1) or what to do about it. Exception information from the log for this error: Exception information: Traceback (most recent call last): File "/Library/Python/2.7/site-packages/pip/basecommand.py", line 122, in main status = self.run(options, args) File "/Library/Python/2.7/site-packages/pip/commands/install.py", line 230, in run finder = self._build_package_finder(options, index_urls, session) File "/Library/Python/2.7/site-packages/pip/commands/install.py", line 185, in _build_package_finder session=session, File "/Library/Python/2.7/site-packages/pip/index.py", line 50, in __init__ self.use_wheel = use_wheel File "/Library/Python/2.7/site-packages/pip/index.py", line 89, in use_wheel raise InstallationError("pip's wheel support requires setuptools >= 0.8 for dist-info support.") InstallationError: pip's wheel support requires setuptools >= 0.8 for dist-info support.
This worked for me: sudo pip install setuptools --no-use-wheel --upgrade Note it's usage of sudo UPDATE On Windows you just need to execute pip install setuptools --no-use-wheel --upgrade as an administrator. In Unix/Linux, the sudo command is for elevating permissions. UPDATE 2 This appears to have been fixed in 1.5.1.
