toad\c_utils.pyx:40:9: 'number' is not a type identifier Cython.Compiler.Errors.CompileError: toad/c_utils.pyx

[biubiu873]

system version Windows 11 python version 3.11.0 Cython version 0.29.33 numpy version 1.24.2

I have tried updating numpy, cython versions。

I used python setup.py install to install the package downloaded from github, but cython showed a compilation error. I downloaded the c++ tool based on other people's experience, but the installation was still not successful。

Below is the error message：

same error when i install it

[Secbone]

@javakenny @myelinji Could you try to install from pip instead of from source code?

[biubiu873]

@Secbone I first failed to install through the pip before installing using the source code, and they all reported the same error.

[biubiu873]

@myelinji My version of python is 3.11, and currently cannot be installed through pip. need to wait for an official update;

However, currently, you can successfully install through the source code. If you encounter an error: Microsoft Visual C++14.0 or greater is required. You can follow the prompts to download https://visualstudio.microsoft.com/visual-cpp-build-tools/ And install python components and C++desktop development components.
