安装 AssimpCy

Question

对于学校项目，我必须使用 Python 的 OpenGL 库。

这是我老师给出的代码的导入部分：

import OpenGL.GL as GL              # standard Python OpenGL wrapper
import glfw                         # lean window system wrapper for OpenGL
import numpy as np                  # all matrix manipulations & OpenGL args
import assimpcy

我成功安装了OpenGL、glfw和numpy的库，但是我无法安装assimpcy。

用 pip 安装它不起作用，我得到这个错误:

然后我尝试自己编译它，所以我按照这个教程：https://assimpcy.readthedocs.io/en/latest/install.html

我下载了已编译并安装的 Assimp，下载了 AssimpCy 的 github 存储库，但是当我启动它时：

python setup.py build_ext -I'/home/alexis/Documents/assimp-5.0.1/include/assimp' -L'/home/alexis/Documents/AssimpCy'

我收到这个错误：

您有什么想法可以帮到您吗？

Answer 1

我猜这个问题是由错误的包含文件夹引起的。而不是这个

python setup.py build_ext -I'/home/alexis/Documents/assimp-5.0.1/include/assimp' -L'/home/alexis/Documents/AssimpCy'

尝试使用这个

python setup.py build_ext -I'/home/alexis/Documents/assimp-5.0.1/include/' -L'/home/alexis/Documents/AssimpCy'

所有 public 包含都位于文件夹 include/assimp 中，将按以下方式包含：

#include <assimp/types.h>

因此，将 assimp-prefix 添加到 include 将为 public include 设置错误的位置。将 include 设置为 include/assimp 时，include 语句将失败。

Answer 2

好的，我终于找到了错误。似乎是在安装 Assimp 的过程中出错了。我刚刚重新安装了 Assimp 并运行 python setup.py build_ext 并且成功了。
