Please find the cause of "Could not build wheels for multidict, which is required to install pyproject.toml-based projects" - Error

I was just trying to install aiohttp in python. So I just typed in console like that: pip install aiohttp . At first, the installation went well, but finally I got the following Error.

C:\Users\1\AppData\Local\Programs\Python\Python312\Scripts>pip3 install aiohttp

[notice] A new release of pip is available: 23.2.1 -> 23.3.2
[notice] To update, run: C:\Users\1\AppData\Local\Programs\Python\Python312\python.exe -m pip install --upgrade pip

So I tried the another one "pip install pyproject". But I can't solve. Please help me!

Solution

  • EDIT

    As of February the 1st 2024, multidict released a wheel for Python 3.12.

    You can download it here, but it will also be updated over the coming days in the affected libraries. aiohttp as an example updated theirs today (02-02-2024).

    END OF EDIT

    I just had this problem and despite the other answer, aiohttp does have Python 3.12 wheels, so it should work.

    This is how I solved it (for Windows using VS Code):

    Download the Microsoft C++ Build Tools as provided in the link: https://visualstudio.microsoft.com/visual-cpp-build-tools/

    enter image description here

    Click Download Build Tools and run it as administrator.

    Accept terms and wait for it to download and install.

    Select the Individual components pane and click off:

    enter image description here

    • Windows Universal C Runtime
    • C++ Build Tools core features
    • C++ 2022 Redistributable Update
    • C++ CMake tools for Windows
    • MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest)

    For Windows 10:

    Windows 10 SDK (Pick newest version)

    For Windows 11:

    Windows 11 SDK (Pick newest version)

    Click install and wait for it to finish.

    Restart Windows or try to restart VS Code and rerun the pip install aiohttp.

    Output after installing the above and running pip install:
