Install Third-Party Python Packages in Blender Using Pip's --target Argument

블렌더 사용자는 원활한 통합을 위해 pip의 `--target` 인수를 통해 블렌더의 `SCRIPTS` 경로를 지정하여 Python 패키지를 설치할 수 있습니다.

### 블렌더에 서드파티 파이썬 모듈 설치하기
* 👨‍💻 블렌더 스크립트 기능을 향상시키는 다양한 서드파티 파이썬 패키지가 존재합니다.
* 📦 이러한 패키지는 블렌더 애드온처럼 블렌더 기능을 확장합니다.
* 💡  `pip` 명령어를 사용하여 패키지를 설치하지만, 블렌더 설치 폴더에 직접 설치하는 것은 권장되지 않습니다 (특히 Windows 사용자).
* 🛠️ `pip install <package_name> --target <path>` 명령어와 **`--target` 옵션**을 사용하여 원하는 경로에 패키지를 설치할 수 있습니다.  **`<path>`는 Blender의 `bpy.utils.user_resource('SCRIPTS').path`를 통해 얻을 수 있습니다.**
* 🐍  예시로 Pillow(Python Imaging Library)를 설치하여 `Image` 클래스를 사용하는 방법을 보여줍니다.  설치 후 블렌더에서 해당 라이브러리를 성공적으로 import할 수 있습니다.
* 👍  본 비디오에서는 Windows 환경을 기준으로 설명하지만, Mac 및 Linux에서도 동일한 방식으로 적용 가능합니다.
* 📁 설치된 패키지는 지정된 경로에서 확인할 수 있습니다.
* 🔗  블렌더 애드온과 함께 서드파티 패키지를 배포하는 방법은 다른 비디오에서 다룹니다.

Python has a great selection of third-party packages that can enhance the functionality of your scripts and add-ons. These third-party packages can

extend Python the same way as add-ons can extend Blender. You just install them and you're good to go. In this video, I'll

show you one of the ways you can install these third-party packages. If you're new here, I'm Victor Stenov and I love

helping artists learn the Python programming language. Recently, I saw a Default Cube video explaining how you can solve the "no module" error that you

can get when using other modules and packages. With this video, I'll be piggybacking on that and adding another

way you can install Python packages. By the way, I highly recommend checking out that video to see other ways how you can

install packages, and I'll leave a link in the description so you can check it out. To install a third-party package, we

usually use a program called pip, which installs packages from the Python Package Index. Pip usually installs the Python package

right into the folder where a Python interpreter is located. And, in the case of the interpreter that is shipped

with Blender, that's going to be inside of the Blender install folder. The problem with this is that not always can you

modify and write into that folder, especially if you're on Windows and you've used the official installer. To

work around this issue, you can use a special command-line argument passed into pip and tell it where pip should install

this Python package you're trying to install. Now, I'll be showing you how to do this on Windows, but the same thing

you could do on Mac or Linux. The command-line argument I'm talking about is `--target`, and then you pass in the

path where you want pip to install the package. You can specify any path you want, but we won't be doing that; we'll be

Using a special path that the Python interpreter in Blender actually knows about, we can get the path to this folder.

By going into Blender, then into the Scripting workspace, and into the interactive Python console down here, and then typing

in the following command: `bpy.utils.user_resource('SCRIPTS').path = modules`.  It's very

important for `SCRIPTS` to be capitalized. Then, type that in, hit Enter, and you'll

get a path. This will be unique to your computer, so you can just copy what you see on screen. I'm going to go ahead

and copy this path right here, then go into my command line and type in `pip install <package_name> --target <path>`.

Now I want to install the Python Imaging Library, also known as Pillow. For example, I want to be able to import this `Image` class. I'm just going to copy this

import statement, go back into Blender, and you can see that I'm not able to import this Python Imaging Library. Now let's

go ahead and fix that by using pip to install this Python Imaging package into a place where the Python that's shipped

with Blender can see it. So now I'm in my terminal and I've written `pip install pillow`—that is the name of the package—

and then `--target` equals the path I just got from running that command a minute

before. Now I can actually open this path right here and see that there's nothing there. You can see that this folder is

empty; there's nothing here. Let's go ahead and run this command, and it finishes successfully. Now let's go back

into that folder, and we have the Python Imaging Library installed right here. Now let's go back and see if we can import

This again, and now after we've installed it, we can see that the Python in Blender can see this Python image library, and

you don't need to write any extra code. Okay, if you learned something new, make sure to hit the like button on this

video. I'll really appreciate it. And now that you know how to install third-party Python packages, how do you ship them

with your Blender add-on? In this video right here, I'll show you exactly how you can do that.
