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:

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.
First, you should never run 'sudo pip'.
If possible you should use your system package manager because it uses GPG signatures to ensure you're not running malicious code.
Otherwise, try upgrading setuptools:
easy_install -U setuptools
Alternatively, try:
pip install --user <somepackage>
This is of course for "global" packages. You should ideally be using virtualenvs.

A program I am trying to install requires the installation of PyQt5 5.15.0 , which gives me this error. The odd thing is that the installation works fine for the latest version of PyQt5 (5.15.2), but this program requires 5.15.0 specifically.

I am on the latest version of pip. Any ideas on the root cause of this issue?
What helped me is upgrading pip from 20.2.3 to the latest one (in my case 21.1.1)
For Mac/Homebrew users.
The answer by #the-x is leading in the right direction. On a Mac with QT5 installed via Homebrew the qmake binary just needs to be added to the path. This can be achieved through
export PATH="/opt/homebrew/opt/qt5/bin:$PATH"
(of course depending on where the homebrew files are installed)
Running on arm with python3.6 (ubuntu18 on nvidia Xavier):
sudo apt install qt5-default
For MacOS users.
I am on Apple M1 silicon using Python 3.9.8. What worked for me was #Apaul's comment in the original question section. Install pyqt5-sip prior to pyqt5.
I also have an Intel Mac and on that machine, I do not need to do this.
Checking the binaries that PyQt5 provides in pypi for version 5.15.0 I see that it does not provide the binaries for python3.9 in windows, so pip is trying to compile using the source code which is complicated and can generate several dependency problems (for example you must have Qt 5.15 installed, etc). So my recommendation is to install a more updated version of PyQt5, for example 5.15.2 since if it provides the binaries for python3.9 on windows, in addition to being a wrapper of an LTS version of Qt then it will have solved several bugs.
python -m pip install PyQt5==5.15.2
Another solution is to use python3.8 instead of python3.9 so that you can install pyqt5 5.15.0 from pypi without problems.
Upgrading your pip enables you to install PyQt5. Personally, I had the same issue while installing PyQt6 and I upgraded my pip, and everything installed perfectly. I think both python and pip versions play an important role in installing PyQt so make sure you have later versions.
This is the command I used in Linux:
pip install --upgrade pip
Combining several answers on this question: On an Apple M1 Pro Macbook with macOS Ventura 13.0.1, with Homebrew 3.6.17 and python 3.11.0 the following commands fixed it for me (no sudo):
brew install qt5
export PATH="/opt/homebrew/opt/qt5/bin:$PATH"
python3 -m ensurepip --default-pip
pip3 install pyqt5-sip
pip3 install pyqt5 --config-settings --confirm-license= --verbose
That last step calls qmake to compile all of Qt on your M1 and takes many minutes to complete, be patient and let it finish.
Since qt5-default was not available, I installed qt5-default's dependencies
sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools
after that I installed pyqt5 via apt-get first and afterwards via pip
sudo apt-get install pyqt5-dev
pip install pyqt5
now wheel seems to work
side-note:
I am not sure if sudo apt-get install pyqt5-dev is even necessary
The error message thrown here is misleading - it's not an issue with a sipbuild.api attribute. Indeed, in this case program qmake is missing, see last line of the Python traceback. Have a look if it's installed on your system and add it to your PATH variable. Otherwise, install it. On Linux this would be done with
sudo apt-get install qt5-qmake
I had this problem on my M1 Mac using Python 3.9.12 when I was trying to install a library: pip install pixellib.
The first thing I did was: pip install pixellib --verbose to see the whole log, and there I noticed that PyQt5 was waiting for an input. So then I found someone else with that issue, and used pip install pyqt5 --config-settings --confirm-license= --verbose which took some time to compile, but worked!
I could not get any of the above solutions to work but I managed to get it working using python3.9, PyQt5=5.15.2, pip=22.0.2 and sip=6.5.0 by using sudo apt-get install PyQt5. If you need it in a virtual environment, you can manually copy the PyQt5 folder from your default /usr/lib/python3/dist-packages to the site-packages folder in your virtual environment.
To all those that are struggling with Apple M1 installation, here is a working solution, specifically addressing the problem of installing the pixellib library that depends on PyQt5 but you can apply it equally to other libs:
PyQt5 is not supported on Apple M1, it needs qt6: https://www.reddit.com/r/learnpython/comments/o4w1ut/comment/h2jele3/?utm_source=share&utm_medium=web2x&context=3 , https://www.qt.io/product/qt6
this means you need to install PyQt6: python3 -m pip install PyQt6
go to the lib you need, in my case pixellib: https://pypi.org/project/pixellib/#files and
download the wheel file
get the wheel tool: pip install wheel
unpack the wheel wheel unpack pixellib-0.7.1-py3-none-any.whl
Change its dependency of PyQt5 to PyQt6
edit pixellib-0.7.1/pixellib-0.7.1.dist-info/METADATA
pyQt5 => pyQt6
pack it back wheel pack pixellib-0.7.1
install it: pip install pixellib-0.7.1-py3-none-any.whl
test in python: `
# should work
import pixellib
P.S. thanks to Terra and ChaOS for supporting work on the project underlying this report.
I finally managed to make it works on M1/M2 Macbook Pro.
None of these answers worked for me, so I looked at brew to install pyqt.
The following command will install pyqt5 via brew:
brew install pyqt#5
Then it just worked.
This can be resolved by switching to an environment with Python >= 3.8

Install cryptography 1.2.1 using below command
sudo pip install cryptography==1.2.1
or upgrade distribute
sudo pip install -U distribute
Ref:
https://github.com/mozilla/sops/issues/67
https://github.com/ARMmbed/yotta/issues/764
The "python-pip" package installs an old version of distribute/setuptools that is incompatible with versions of cryptography >= 1.3.
The cryptography library specifies a dependency on setuptools >= 11.3:
https://github.com/pyca/cryptography/blob/master/setup.py#L40
However, this requirement isn't getting met because setuptools has been installed by the OS's packaging system rather than by pip. When pip tries to upgrade setuptools, the upgrade fails (but doesn't cause the installation of cryptography to actually fail.)
Running:
sudo pip install -U distribute
Forces setuptools to be upgraded (the distribute package has been renamed to setuptools in later releases). You could also do:
sudo pip install -U setuptools

If you get an error that a specific dependency isn't being met, being more specific about that dependency usually helps. I like to put dependencies that I don't directly use in a before_install section.
before_install:

pip allows you to specify constraints on the versions of packages you install. If you had to use 1.3 exactly you could use ==.

What happened? How do I fix this
Try updating your setup tools manually.
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
sudo python ez_setup.py --user
Following an answer on a different question about pip vs. easy_install, you can uninstall a package that was installed with easy_install using pip:
sudo pip uninstall distribute
This removed the offending version of distribute, and easy_install works again.
I had same problem, then i found that there is easy_install-2.7 and I can install packages properly.
