AttributeError: module 'sipbuild.api' has no attribute 'prepare_metadata_for_build_wheel' for PyQt5 5.15.0

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

PyQt5 dependency in a module on Debian [duplicate]

This question already has answers here:
Install PyQt5 5.14.1 on Linux
(8 answers)
Closed 3 years ago.
I have a Python module with a __main__ that uses PyQt5. I've installed PyQt5 on a Debian Buster box:
apt-get install python3-pyqt5
The __main__ program runs as expected if I execute
python3 mymodule/__main__.py
from the source directory. Now I've installed the module into python:
python3 setup.py install
That worked. The setup.py lists a dependency on pyqt5:
setup(
# ...
install_requires=['PyQt5'],
entry_points={"gui_scripts": ["mymodule = mymodule.__main__:main"]},
Setup created a script /usr/local/bin/mymodule. When I run that, I get an error message:
pkg_resources.DistributionNotFound: The 'PyQt5' distribution was not found and is required by mymodule
What am I missing?
EDIT: tried installing pyqt5 via pip, got the following error:
seva#sandbox:~$ sudo pip3 install pyqt5
Collecting pyqt5

OS-level package managers are designed to be consistent within itself. But they aren't designed to interoperate with language package managers. apt-get-installed python3-pyqt5 could be recognized by other Debian packages but not by pip/setuptools.
So either you convert your package to .deb (using stdeb, for example), set dependency to python3-pyqt5 and install it with apt/apt-get/dpkg. Or you install everything using pip:
pip install pyqt5
pip install . # to install your package
If your dependencies are properly declared in the package the latter command should be enough — pip will run the former itself.
PS. Also please consider virtualenv to separate pip-installed packages from system-installed. virtualenv itself could be system-installed or user-installed:
apt install python3-virtualenv
or
pip install [--user] virtualenv

Errors by installing Python modules Pygame and Pygame Zero

I've succesfully installed Python version 3.8.1 and also PIP.
After that i want to install Pygame and Pygame Zero with the commands
pip install pygame
or
pip install pgzero
But I get the following error:
C:\>pip install pygame
Traceback (most recent call last):
File "c:\program files\python38\lib\runpy.py", line 193, in _run_module_as_main
return _run_code(code, main_globals, None,

exec(code, run_globals)
File "C:\Program Files\Python38\Scripts\pip.exe\__main__.py", line 9, in <module>
TypeError: 'module' object is not callable
Also with the --user command it doesn't succeed:
pip install pygame --user
or
pip install pgzero --user
What am I doing wrong here now?

I also got that problem long ago.
You can try this:
pip uninstall pygame
pip uninstall pgzrun
then download it by:
pip install pygame
pip install pgzrun

Info of your assets are little low.. But if you have Python 2 and 3, try manage your alias on CMD by checking your current python variables from /usr/bin and from CMD type "python --version" to see current default. If it says Python2.7 you can chance that with "alias" command below (reason to do that, is 2.7 support is ending 1.1.2020 and old pip for it too. So in future, you should upload new modules just for Python3.7). If you have 2.7 in your PC and you have been using it for some time, you should not try to remove it.
So just in case:
$ alias python="/usr/bin/python3.7"
Then use command
$ sudo pip3 install pygame
This should work. If not, there is some setting problems on your module site.
Give a hit with this and if it doesn't work, let us know. I can give instruction to get it to work. It requires few steps at (in my case:)
/home/usr/Python-3.7.4/Modules/Settings.
It can (I'm not sure with these modules but..) require to set SSL connection too, but it can be done from there too, without any coding.

Thank you for the quick arswers!
It is succeeded by giving the commands:
py -3 -m pip install pygame --user
py -3 -m pip install pgzero --user
The only warnings i got by installing pgzero were:
Collecting pgzero

Oh.. I didn't know, you are using Windows.. My last answer dried down with that. It was for Linux.
Either way, when you installed python, did you mark the PATH in installation process?
It shows when installation windows pops up.
I'm little noob with windows, but I expect it to be as same as in any operation systems.
If you didn't, its easier to remove Python and install it again, than try to mark the PATH after installing. After all its just 1/2 min job.

Easy_install and Pip doesn't work

Easy_install and Pip doesn't work anymore on python 2.7, when I try to do:
sudo easy_install pip
I get:

I've already install both of them (and yes, first deleted them), but no result...
Thanks!
(I tried already this post)

I had this issue where python's distribute package wasn't installed for some reason. After following the instructions on python-distribute, i got it working.
install the distribute package as follows:
$ wget https://web.archive.org/web/20100225231201/http://python-distribute.org/distribute_setup.py
$ python distribute_setup.py
EDIT: http://python-distribute.org/distribute_setup.py no longer works:
hopefully this will resolve your problem with running
$ sudo easy_install
Happy Coding!

If you installed a new version of easy_install through Distribute, the new command may have been installed in another directory, most likely /usr/local/bin/. But the traceback shows you were using /usr/bin/easy_install. Try this:
sudo /usr/local/bin/easy_install ...

Try
sudo easy_install Distribute
and if that exists, but is too old
sudo easy_install -U Distribute
Looks like either Distribute/setuptools (it's old name) is messed up or Python package settings. If either of these do not help, try removing the full Python 2.7 installation and reinstall everything from the scratch.
Possible reasons for the mess is that you have used both sudo easy_install / sudo pip and Linux distribution packages to mix and match system-wide installation packages. You should use virtualenv instead if you use pip/easy_install (no sudo needed)
http://pypi.python.org/pypi/virtualenv

I had a similar problem, but things were working fine as root. In my case, I found that the permissions on the python packages were not readable by the ID I was running the command under.
To correct it, I ran the following command to open the permission for read and execute to all users:
sudo chmod o+rx -R /usr/local/lib/python2.7/dist-packages/*.egg

I had similar issue when trying to install package via pip with python 3.6 on windows. (pip is supposed to work out of the box with this install)
The problem was not running as administrator.
Running cmd as administrator and then installing my package worked:
python -m pip install pylint

I was trying to get pip to work on the 2.7.0 version, but it seems like it doesn't come with the easy_install/pip files (Script folder in main directory), installing 2.7.13 solved the problem for me.
