About bpy environment

[NoLookDefense]

Hey bro. I am coming again for the another problem.
I want to run the new feature which can export the mesh to .fbx file, and it seems that "bpy" package is needed to download. But when I use pip install bpy, some CMake error always occurs.
I wonder that which version of CMake you are using when you install bpy?

[Arthur151]

cmake version 3.10.2
Thanks for your attension.

[NoLookDefense]

cmake version 3.10.2
Thanks for your attension.

And how about the bpy version?

[Arthur151]

bpy 2.91a0

[NoLookDefense]

Complete the same. But I meet error while importing bpy. I am using ubuntu18.04 and python 3.7.10

Have you met such a problem before?

[Arthur151]

It is the bug of bpy. I have also met this before.
Here is a solution that worked for me.
Besides, according to the official instruction, the correct installation might be:
pip install bpy && bpy_post_install

[NoLookDefense]

Thank you. It works.
It seems that the functions have been achieved. But there is an error at the final stage.

But the .fpx file is exported successfully. I don't know if this error matters, because the animation in blender seems strange...
The person is facing to the ground, and his arms seem horrible due to the strangle traingle.

[Arthur151]

I am really happy that you finally made it.
It seems that you are unfamiliar with the Blender...
You can rotate the view by pressing the Middle mouse button and moving..
The 'strange triangle' you mentioned is his bone. You can choose to hide it through manipulating the scene collection (at the top right).

[NoLookDefense]

Thanks for your help! It runs!

BTW, there is another problem I want to mention. Will the .fbx model compatible with Unity?

[Arthur151]

Here is a portable way: export the Blender fbx model to fbx compatible with Unity.
Here is a video which introduce this simple action.
