I was tring to install PyQt5 and a get this error:
note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed
× Encountered error while generating package metadata.
╰─> See above for output.
note: This is an issue with the package mentioned above, not pip.
hint: See above for details.
I've tried using brew install pyqt and installing pyqt6 went out just fine. What's wrong.
Ok, I faced this issue with python 3.10.4 and after searching I found two solutions for this problem because this problem not being only with turtle but for other libraries.
#Note: These solutions for downloading any library if you have a problem mentioned above and this problem faced me in windows CMD.
So you could try this way:
pip install <libraryName>==0.0.1
0.0.1 This is the last version of the library so you should find the version of the library that you want to install for this purpose, you can find the version of the library using this command:
pip show module <name_of_the_library>
another solution that could work is using --use-deprecated=backtrack-on-build-failures
Example:
pip install turtle --use-deprecated=backtrack-on-build-failures
Hope to help you.

Unable to install Pygame using pip

I am trying to install the pygame library on my Mac running macOS 11.0 Big Sur, but I keep getting errors related to missing files, such as 'longintrepr.h' and 'pkg-config'. I have tried installing the library using pip3 and a virtual environment, but I am still encountering the same issues. I am looking for a solution to successfully install the pygame library on my Mac.
#include "longintrepr.h"

I have the newest version of python3 installed.
I tried to install pygame using pip on my MacOS machine but I encountered an error "src_c/_sdl2/sdl2.c:211:12: fatal error: 'longintrepr.h' file not found" during the installation process. I also tried creating a virtual environment and installing pygame there but still encountered the same error. I was expecting the installation process to complete successfully without any errors.
On the official pygame repo, there's a huge thread regarding installation of pygame in python 3.11 (latest version) not working properly yet.
Try installing pip install pygame --pre for now, which is going to install a developmental release of the newest, prereleased pygame version, or if you want stability using an older version of python also works.
I am trying to use a piece of software that has been developed for use, specifically with Python 3.5.2. This version is no longer available. When running the setup batch file, I get a legacy-install-failure

I am struggling to find a suitable version of Python to see if this is a forward compatibility issue or something else?
Thanks
I'm trying to install the package spectral-cube from the astropy project using pip (22.0.4). I get a long error which ends with this:
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for casa-formats-io.
Failed to build casa-formats-io.
ERROR: Could not build wheels for casa-formats-io, which is required to install pyproject.toml-based projects
Even after downloading casa-formats-io from their github I still get this error.
I've also tried installing this using conda, but the error is the same.
I'm using MacOS 12.3. But I had the problem with older versions.
I'm kind of confused as to what I can do.
Thanks for the help!
I was able to fix my own problem. The error appeared because the package I was trying to download wasn't available/compatible with the newest python version (3.10). So, I simply uninstalled Python and downloaded an older version (3.8).
Thanks anyways :)

SmartAPI requires Python 2 (see the bottom of the left column). Try Python 2.7. Or find out a different package.

As per the official documentation, I've tried creating different environments with different versions of python, but it doesn't seem to work!
Please let me know if anyone knows a way around the problem. Thanks!
