Error while installing pytq5 with pip: Preparing metadata (pyproject.toml) did not run successfully

  1. How to solve Error while installing pytq5 with pip: Preparing metadata (pyproject.toml) did not run successfully


    MacOS-specific answer
    You need to have Qt5 installed in the system, and you need to have its qmake in PATH.
    To install Qt5, you can either run brew install qt5 or download the installer from https://www.qt.io/download-qt-installer.
    Note that if you choose to use the installer, it will require you to log in to or create a qt.io account to perform the installation.
    If you have an older version of MacOS, you can download older installers from https://download.qt.io/archive/qt/. You can check which version supports your OS version in https://doc.qt.io/archives/qt-5.14/supported-platforms.html, where you can swap out qt-5.14 in the url for whichever version you are interested in.
    After the installation, find where qmake is located. For me using the installer for 5.14.2 it was in /Users/Admin/Qt5.14.2/5.14.2/clang_64/bin. You need to add this to the PATH environment variable. To do so edit .bash_profile in your home folder (may need to press Command + Shift + . first to see dotfiles in Finder) and add to it something the following:
    export PATH="$PATH:/Users/Admin/Qt5.14.2/5.14.2/clang_64/bin"
    Now, upon launching a new terminal, you should be able to type qmake and see its help text be outputted. Installing PyQt5 should now succeed (provided the Qt5 version you installed supports your MacOS version).

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 faced me in windows.

So you could try this way:

pip install turtle==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.

I faced the same problem these days. When you have a look at PyPi download site, you can read in the Installation chapter that you need “Qt’s qmake tool on PATH”. After installing Qt’s development files everything worked fine for me. So first install it and make sure it’s on your PATH and than try again.

sudo apt-get install qtbase5-dev
pip install pyqt5

PS: I think it has nothing to do with your python or pip version. I tried many versions and had this problem every time. It’s just missing, corrupted or not found header development files from qt5.

I got that same error and I fixed it just by uninstalling 3.10 and installing 3.9.
