无法使用 pip 安装包 bpy
Cannot install package bpy using pip
问题描述:
在 VS Code 中，运行 命令 pip install bpy（如 https://pypi.org/project/bpy/ 所示）并得到以下错误消息：

-------- 我试过的（没有成功）：------
安装轮子（pip install wheel），然后从pypi.org下载包手动安装：
pip 安装'C:\Users(...)\Downloads\bpy-2.82.1.tar.gz'
遇到同样的错误。
-------- 结论：------
不能在 Blender 之外使用 bpy。我在 Blender Stack Exchange 上的另一个 post 上找到了一些解决方法（我还没有尝试过）
感谢 Anand 和 phd 提供的非常有用的链接！
不幸的是，‘bpy’模块不能在 Blender 之外使用。
这里有更多详细信息：https://creativepolygon.com/development/starting-with-bpy-blender-python-part-1-installation
据我了解，实际上可以 运行 在 blender 之外进行 bpy，并且声称其他信息是为旧版本编写的。我不得不承认，我仍在安装 bpy，这不是一件容易的事，我还无法验证这一点。
在您的情况下，缺少 pip 模块。您可以使用 pip install future_fstrings 安装它。查看 https://pypi.org/project/bpy/ 了解更多指南。
编辑：我能够在 Windows 和 Linux 下安装 bpy。它在 Linux 上抛出一些错误，但在 Windows 下工作正常。绝对独立工作！
我试了很多次，发现使用3.7.6的Python版本和20.2.4的pip版本，我能够通过pip安装bpy版本-2.82.1安装 bpy。我正在使用 Windows 10 和 Anaconda 提示符。
TL:DR- 从预制轮安装，而不是从标准 pip install bpy && bpy_post_install
在 macOS 上安装错误：
过去 8 小时左右我一直在尝试安装它。
到目前为止我的安装步骤：
- 我按照 blender.org
上的说明从源代码构建了搅拌机应用程序
- 根据 bpy github 存储库，bpy 依赖于 bpy-build（尽管它不在先决条件中）。
- bpy-build github 存储库没有很好的安装说明，setup.py 脚本专门将 OS 声明为 windows。所以，我基本上只是跳过了这个 - 安装失败的可能原因。
- 在两次不同的尝试中，我同时使用了 pyenv 和 virtualenv，以创建一个 python 3.7 开发环境。在
setup.py 的 运行 期间，两者都导致了 pip install bpy 的挂起安装。 pip 安装的实际错误是：

**** 突破 ****
在写这篇文章时，我注意到 bpy github 页面中的选项是通过预构建轮而不是通常的 pip install bpy && bpy_post_install 安装。你必须去一些 'sketchy' 网站下载文件，但在我下载并安装它之后，我能够 运行 在 blender 应用程序之外运行 blender 脚本！！
我猜你无法安装 bpy，因为你正在通过 python 3.8 版本安装 bpy。
您已经降级 python version to 3.7
查看https://pypi.org/project/bpy/
然后你可以看到bpy模块需要Python >=3.7, <3.8
的版本
