Already tried python_embeded\python.exe -s -m pip install --force-reinstall ninja. I even slip subprocess command to get pip list (as json) in the code to see the installed package, the ninja package clearly installed but the error still persist.
Any Idea to solve this problem is appreciated!
@cupret Hi, I think someone had a similar issue before, couldn't find it though, but to solve it, you need to add D:\SD\ComfyUI\ComfyUI_windows_portable\python_embeded\Scripts into your environment path variable and move it onto the top of list
The reason is, your system is trying use Ninja somewhere else, but it is not installed correctly at the location where your system is looking.
Let me know if that solves your problem, cheers

Thanks for the reply. While the the ninja error is gone, a new error appeared.

It seems its trying to install/import file nvdiffrast_plugin_gl.pyd from C:\Users\User\AppData\Local\torch_extensions\torch_extensions\Cache\py311_cu121\nvdiffrast_plugin_gl\, yet there is no such file, only a file named build.ninja exist on that directory. I suspect there somethings wrong with how ninja build the extensions, yet there is no error thrown from ninja. (I already have VS2022 installed with c++ component)
I am also getting a similar error, though I do have a nvdiffrast_plugin_gl.pyd file in C:\Users\User\AppData\Local\torch_extensions\torch_extensions\Cache\py311_cu121\nvdiffrast_plugin_gl.

Open a cmd window, navigate to the location of build.ninja, and manually build it. I think the command is 'ninja build.ninja'
This will almost certainly fail, but it will tell you the errors that got suppressed when Comfyui tried it
DLL not found is just a pathing issue.
Either add the path to the pyd file to your environment path, or copy them to somewhere they will be found.
I copied the whole folder to python\Lib\site-packages\nvdiffrast_plugin_gl

In my case, ComfyUI-3D-Pack became unimportable after updating it in comfyui manager. The same thing happened to me and it won't import. I'm not sure how to fix it by changing the environment path variable, would appreciate it if you could let me know.

This solved the error RuntimeError: Ninja is required to load C++ extension for me. Thank you.
