Tried to install PyQt5-tools via pip, didn't work [duplicate]

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.
Command Output:

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

It seems that you have pip aliased to the pip install command for some reason.
You could probably just run pip tweepy to actually run pip install tweepy, but the better method would be to run pip via the Python interpreter. Upgrading pip this way could also potenitally fix the aliasing.

Tried different ways like pip3 install tweepy and pip tweepy like the solution advised above but that didn't work. Tried upgrading and reinstalling pip but still no solution. Had to do a whole reinstallation of python environment.

Try installing in lower version of python. Some libraries doesn't support a new version of python immediately.

How to install SciPy on an Azure C# webapp?

I have a website built with .Net Core 1.0 (C#) and deployed it to Azure WebApp (32 bit mode).
The app uses some python scripts and I was able to create a virtual env (3.4.1) and successfully installed numpy (1.11.0) with pip install numpy.
The problem I'm facing is that I can not install SciPy. Trying pip install scipy fails because of compiler issues which I understand.
Next try was to download Christoph Gohlke's Python Extension Packages for Windows (from here), copied it to my web app and tried to run 'pip install scipy-0.18.0-cp34-cp34m-win32.whl' without success. The error I get is:
scipy-0.18.0-cp34-cp34m-win32.whl is not a supported wheel on this platform.
Storing debug log for failure in D:\home\pip\pip.log
pip.log contains the following:
scipy-0.18.0-cp34-cp34m-win32.whl is not a supported wheel on this platform.

pip.exceptions.UnsupportedWheel: scipy-0.18.0-cp34-cp34m-win32.whl is not a supported wheel on this platform.
I have tried to create a requirement.txt file as stated in Troubleshooting - Package Installation. However since it's not a python app, but instead a dotNet Core C#, it doesn't seem to care about the requirement.txt file and don't see anything about it in the deploy.cmd file.

#mdeblois, your understanding is correct, please see the offical explaination below.
Some packages may not install using pip when run on Azure. It may simply be that the package is not available on the Python Package Index. It could be that a compiler is required (a compiler is not available on the machine running the web app in Azure App Service).
For this case, the solution is that you can refer to the section Troubleshooting - Package Installation of the offical tutorial to know how to deal with.

The package was installed fine, but I cannot build wheels. I tried re-installing distribute manually by downloading a zip and running python setup.py install. That installed wonderfuly, without a hitch. But I still have the above problem.
How can I re-define sys_platform?
Alright, I rolled back to x86 good ole 32 bit Python, and I still have the problem. This is really concerning, because I cannot reset this after re-installing. I looked at markerlib, which looks promising, but I don't know how to use it safely. Currently I am unable to install pretty much anything from PyPI, so I am giving points to increase interest.
Any help? I really want to be able to use PyPI again.
I chose the selected answer as it is the most likely to solve the problem. I myself have moved back to x86 Python, so I cannot test this myself. Therefore, I encourage future visitors to try this answer, but I have not myself been able to test it.

Might be a bug. Check out: https://bugs.python.org/
You can manually check the markers.py file and try to fix it. I think there would a reference to sys_platform that has to be changed to sys.platform
Regarding markerlib, you can try this out-
import markerlib
marker = markerlib.compile("sys.platform == 'win32'")
marker(environment=markerlib.default_environment(), override={'sys.platform':'win32'})

To fix this error, I found that installing the 0.7.3 version of distribute fixed this. I had also upgraded setuptools and pip along the way (so they may be needed as well), but after upgrading distribute this error finally went away.

Try removing pip and distribute and setuptools, and then manually install pip using get-pip.py .
Then , download setuptools from here , extract -> go inside the extracted folder in command prompt and do python setup.py install
Then , download distribute from here , extract -> go inside the extracted folder in command prompt and do python setup.py install

I ran into this issue today myself, though on OSX. I had run --upgrade as well as trying to uninstall and reinstall it completely.
Eventually, though I went into my site packages, and saw a "correct" version of setuptools (18.1) AS WELL as an older lingering version of it (completely separate version 15.1 of it). Removing it all and reinstalling setuptools fresh fixed it for me.
Hopefully this helps someone else!

I had an old verison of distribute, which didn't correctly resolve dependencies. It was fixed with
C:\Users\cshucks>pip install --upgrade distribute

PyCharm 3.0 fails to find PyQt5

I've got Python 3.3.2 installed (both x86 and x64 versions) and PyQt5.1 installed on top of them.
Recently I installed PyCharm 3.0 Community Edition and configured to work with these Python interpreters. The problem is that PyQt5 is not shown in the list of installed packages and documentation is not working (both Ctrl+Space to autocomplete and Ctrl+Q for docs).
When PyCharm is quering skeleton generation it seems to process PyQt but to no use. When I try to install PyQt using packages system inside PyCharm, I get following error:

I've found log from previous index invalidating I tried to make things work. The log contains no errors or warnings concerning PyQt. Specifically it reads as follows:

But there are no errors reported still.

Couldn't install in pip either but building from source worked fine for me. As mentioned on the comment the .exe file doesn't come with documentation and i think pycharm wouldn't like that because qt its c++. Download here.
if you dont want to build from source then check where did the exe file install qt5. Probably the install went fine but the dir installed is not in the path.

pip install https://github.com/pyinstaller/pyinstaller/tarball/develop
The above syntax downloads the pyinstaller
Pip install pyqt5
Make sure you have pyqt5 file in the pyinstaller in users\appdata..etc
