没有名为“bpy”的模块，但已安装

Question

I've been trying to install bpy for a few hours. I used 'pip install bpy', and got some errors about the 'bpy_types' module. I followed this thread and found the bpy_post_install executable. I also tried the steps involving the 2.82 folder from \Scripts. After I ran bpy_post_install, python is unable to find bpy whatsoever when I run through VSCode. I run python3 __init__.py and get error line 4, in <module> import bpy ModuleNotFoundError: No module named 'bpy' . I then attempt pip install bpy and get Requirement already satisfied: bpy in C:\users\... (2.82) .

I'm pretty much at a loss, I've never seen python claim a module wasn't installed when it clearly is.

Answer 1

I see that you're having an issue with bpy seeming not to be "installed" (I put that in air quotes since you obviously installed it with the terminal.)

Firstly I watched this video - Blender Addon #1 - Python Programming Introduction (Bpy module, data, Context and Types) Which gave me some useful insight into both the bpy module and how you can use it.

In the video he breaks down some of these things so you don't have to watch an 18 minute video.

Prerequisites?

• Basic Knowledge of OOP, Python, and Blender (Object Orientated Programming = OOP)

His tutorial Scripting Tab under the application name, window, and exit buttons very far right.

It opens something called a REPL window

• Read
• Evaluate
• Print
• Loop

When I tried this it worked, and also did not work which is seemly weird

• When I opened one of my complex modules that I was going to use for Three.Js it worked flawlessly - type bpy and then hit tab it should show up with all of the prefill answers

• However, when I used a new blender file with the cube it started giving me errors.

Now about the error you are facing here is what I found

Blender Stack exchange

• People have said that bpy is only available inside of blender from the Python Interpreter itself. However, this is old and from 2013. Here is the thread

Github

• There was a thread (which is linked) that had more or less the same issue.
  • CarlosDubarreto on Apr 26 said that you could use conda to install the bpy module
  • However, he states that it may only work if you are using at least miniconda. Referenced Used

What is conda?

• Conda is an open source, cross-platform, language-agnostic package manager and environment management system Conda Documentation

Difference between conda and pip

• Is what they put packages in. Pip packages are Python libraries like NumPy or Matplotlib. However, conda packages include Python Libraries, C Libraries, and executables like C compilers, and even the Python interpreter itself.

To get bpy to work with the Conda Method mentioned above.

• Conda install page

After installing Conda run this line of code mentioned in the GitHub method above

conda install -c kitsune.one python-blender

---

Alternative Method

• Within the GitHub thread xiezhongzhao said you could install fake-bpy. Link to fake-bpy

• The line he mentions to run is:

  pip install fake-bpy-module-2.80

However I recommend running this line instead, and it's mentioned in the GitHub repo above

pip install fake-bpy-module-latest

I recommend this since it will be the latest version not a specific blender version

However, people within that GitHub thread have said they are still getting errors related to bpy within Python so try it and let me know.
