Unable to install

[ravidraj10]

Unable to install PyMCubes via pip. While installation it says "error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/" I already installed the tool still facing the same issue.

If you keep getting the same error it is very likely that you didn't install some required packages from the Visual C++ Build Tools. Check that you installed the packages mentioned in this short tutorial.

In any case, I just uploaded a Python wheel for PyMCubes to the PyPI repository. That means that you can install a pre-compiled binary version of PyMCubes for Windows by running pip install PyMCubes (or pip install PyMCubes --no-cache-dir to avoid compiling the already downloaded source package). This will install the binary package (no compilation required) if you have a setup compatible with the wheel.

Hi @pmneila @ravidraj10 I am working on my research and needed PyMCubes for fine outputs. I get the same error as @ravidraj10 . I have tried installing using pip install PyMCubes --no-cache-dir, it gives an error no such option: --no-chache-dir. How should I proceed further?

Hi @bharadwajdhornala

I uploaded a wheel for Windows to PyPI. It should work now.

it gives an error no such option: --no-chache-dir

It looks like a typo. You wrote chache. It is cache.

Hi @pmneila Will it work only when I install Microsoft Visual C++ 14.0? Can it work with any version.

[pmneila]

No, now it should work without MSVC++. I uploaded a precompiled binary. You should get it with

pip install PyMCubes --no-cache-dir

I have tried to install using pip install PyMCubes --no-cache-dir . It gives the same error--Microsoft Visual C++ needed

[pmneila]

What Windows version do you have? Is it 32- or 64-bit? The precompiled binary is 64-bit only.

Can you copy the entire output of pip install PyMCube --no-cache-dir?

[bharadwajdhornala]

It is 64-bit.

Hi @bharadwajdhornala

I think I see the problem. The wheel has been compiled for Python 3.7, but from your log it seems you are using Python 3.5. Would it be possible for you to update your Python to version 3.7? Otherwise, you will need to install MSVC++ or wait until I build the package for Python 3.5 (which might take some time).

Blender 2.9 Sverchok Extra Nodes install PyMCubes (geomdl as well) points to this website (comparable for geomdl).

Install succeeds, under Python3.8

Followup on install is that Blender uses Python3.7

Do I need to switch install to Python3.7? If so, how?

If not, it shows installed but, is not recognized by Blender 2.9 (MacOS - Catalina).

Hi @Kunal-sanjay-saxena

What command did you run to get that error message? In principle you should not need to compile PyMCubes, as there are wheels available when installing it with pip install PyMCubes.
