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

while installing apex extension for pytorch(python environment) the following error is showing, am unable to solve this problem

XGBoostLibraryNotFound: Cannot find XGBoost Library in the candidate path, did you install compilers and run build.sh in root path?

I am facing this problem while moving the python-package directory of XGBoost.
Traceback (most recent call last): File "setup.py", line 19, in LIB_PATH = libpath'find_lib_path' File "xgboost/libpath.py", line 46, in find_lib_path 'List of candidates:\n' + ('\n'.join(dll_path))) builtin.XGBoostLibraryNotFound: Cannot find XGBoost Library in the candidate path, did you install compilers and run build.sh in root path?
Could anyone explain to me how to fix it?
thanks in advance.

You get that message when trying to install the xgboost Python package without the xgboost binaries present. The proper way to install the xgboost Python package from source is the following (assuming you have a compiler such as gcc installed):
git clone --recursive https://github.com/dmlc/xgboost.git
cd xgboost
./build.sh
cd python-package
python setup.py install
I prefer to do it inside a virtual environment. Note that the option --recursive when cloning the repo is essential since it will also clone folders from different repos such as dmlc-core which are necessary for building xgboost.

The other answers didn't work for me so I installed xgboost through Conda commands as listed here.
Just run conda install -c conda-forge xgboost

The first answer's suggestions did not work for me, and left me with the same error as the original question.
If I'm assuming correctly that your full error message is something like this:
C:\Users\Matt\xgboost\python-package>python setup.py install
Traceback (most recent call last):
File "setup.py", line 19, in <module>
LIB_PATH = [os.path.relpath(libfile, CURRENT_DIR) for libfile in libpath['find_lib_path']()]
File "xgboost/libpath.py", line 49, in find_lib_path
'List of candidates:\n' + ('\n'.join(dll_path)))
XGBoostLibraryNotFound: Cannot find XGBoost Library in the candidate path, did you install compilers and run build.sh in root path?
List of candidates:
C:\Users\Matt\xgboost\python-package\xgboost\xgboost.dll
C:\Users\Matt\xgboost\python-package\xgboost\../../lib/xgboost.dll
C:\Users\Matt\xgboost\python-package\xgboost\./lib/xgboost.dll
C:\Users\Matt\AppData\Local\Programs\Python\Python35\xgboost\xgboost.dll
C:\Users\Matt\xgboost\python-package\xgboost\../../windows/x64/Release/xgboost.dll
C:\Users\Matt\xgboost\python-package\xgboost\./windows/x64/Release/xgboost.dll
then the solution is to
1) Get/find/download the library that setup.py is looking for. Search the xgboost folder for .dll files. See if you can find something like xgboost.dll it might be called libxgboost.dll. If you can, move to step 2. If you cannot find it download it here
2) Copy the .dll file into the xgboost/python-package/xgboost folder. If that .dll is not called xgboost.dll (i.e. if it's called libxgboost.dll) then change the name to xgboost.dll
3) Run the commands as outlined in Gustavo answer. Note these are meant to be run from Git Bash.
If you want a more soup-to-nuts tutorial, this was the best one I found.

thanks to Joe Nyland that found the a good answer for this problem in here.
As he said (and also worked for me) you need to run following commands:
$ brew install gcc#5
$ pip install xgboost

Try this it worked for me:
brew install gcc-5
brew install cmake
pip install xgboost

In my case (Ubuntu 16.04, with CUDA 9.0) the Python library build was evidently broken by adding R library package to the cmake options list:
1) python lib installation works OK:
cmake .. -DUSE_CUDA=ON -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-${CUDA_VER}
cd /tmp/xgboost/python-package && python3 setup.py install
2) adding '-DR_LIB=ON' switch to cmake breaks subsequent python library installation attempt:
cmake .. -DUSE_CUDA=ON -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-${CUDA_VER} -DR_LIB=ON
cd /tmp/xgboost/python-package && python3 setup.py install
> "XGBoostLibraryNotFound: Cannot find XGBoost Library in the candidate path, did you install compilers and run build.sh in root
> path?"

I had the same issues. I downloaded the file (xgboost.dll) from
(https://picnet.com.au/blog/xgboost-windows-x64-binaries-for-download/)
into the already existing xgboost folder
(C:\Users\Naganandini\AppData\Roaming\Python\Python37\site-packages\xgboost).
It's perfectly working now :)

I faced the same error while installing xgboost using anaconda prompt because the installation of xgboost was interfering with the versions of some other pre-installed libraries. Installing xgboost by creating a virtual environment solved the issue.
On macOS and Linux:
python3 -m pip install --user virtualenv #Install virtualenv module
python3 -m venv env #Create a virtual environment 'env'
source env/bin/activate #Activate virtual environment
pip install xgboost #Install xgboost
On Windows:
py -m pip install --user virtualenv #Install virtualenv module
py -m venv env #Create a virtual environment 'env'
.\env\Scripts\activate #Activate virtual environment
pip install xgboost #Install xgboost
Refer https://packaging.python.org/guides/installing-using-pip-and-virtual-environments for help regarding virtual environment.

Search for xgboost.dll file under your C:\Users<your-user-name> directory.
If you have installed xgboost, somewhere you should find a copy of the xgboost.dll file.
Once you find the xgboost.dll file, just copy it to one of the paths mentioned in the error message,
e.g. C:\Users<your-user-name>\AppData\Roaming\Python\Python37\site-packages\xgboost\ . Import should work now.

1.I started off with the conda installation from anaconda prompt:
(base) C:\Users\abhi.b>conda install -c anaconda py-xgboost
This lead to the following error :

2.There after i followed "The final attempt that works " on the below link :

BTW the link to download xgboost.dll as posted above -
https://picnet.com.au/blog/xgboost-windows-x64-binaries-for-download/
was not clear to me ,so i decided to not follow this thread.
3.Finally ,the solution was very simple for me,Open ANACONDA PROMPT and Type
(base) C:\Users\abhi.b>pip install xgboost
This lead to

Trouble installing pygame. Permissions Mac OS X 10.9.5

I have been struggling to find the correct research to install pygame for about 2 days and would like to ask the community to reach a solution!
My MacBook is a backup of my old MacBook so if that is the essence of the problem, I am open to suggestions to fix it!

Then un-installed and reinstalled pygame, following the comments here: https://www.reddit.com/r/Python/comments/2jfj1w/how_to_install_pygame_on_osx_1095/. Specifically the comment by redditor PigBoyOhBoy (with some adjustments for Python 2.7 rather than Python 3).

For python, install hdf5/netcdf4

Doing this on a Linux Mint 17.1.
When I try:
pip install hdf5
I get the error
"Could not find a version that satisfies the requirement hdf5 (from versions: )

I'm trying in the long run to install netcdf4 but can't do that until I get hdf5 installed. Supposedly from when I was trying to do this last week, with netcdf4, I should be using the pip install netcdf4, err hdf5...at least maybe in the case of hdf5.
If I try pip install h5py I get that the message saying:

Yet if I go ahead and try pip install netcdf4 it comes up and says:
Collecting netcdf4

When I search the files I don't find a hdf5.pc file.
Is there a difference between h5py and hdf5? Do I have to compile and install hdf5 from the individual files or can I pip install.
What do I have to do to be able to install both hdf5 and netcdf4?

You need to install the HDF5 libraries for your Linux distribution. In Ubuntu is:
sudo apt-get install libhdf5-serial-dev netcdf-bin libnetcdf-dev
See this link.

I had the same issue in Debian 8. To fix it, as root, I installed the libraries, then linked the serial headers to a include dir inside the hdf5 libraries, exported the HDF_DIR path and installed netCDF4:
# apt-get install -y libhdf5-dev libnetcdf-dev
# ln -s /usr/include/hdf5/serial /usr/include/hdf5/include
# export HDF5_DIR=/usr/include/hdf5
# pip install netCDF4

I had the same error under macOS Catalina. Had to install the hdf5 and netcdf4 packages from Homebrew:
brew install hdf5 netcdf4
Afterwards, pip3 install netcdf4 worked fine.
