安装辅助

Question

对于一个学校项目，我必须使用Python的OpenGL库

以下是我的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，但我无法安装Assimcy

使用pip安装它不起作用，我遇到以下错误：

然后我试着自己编译它，所以我遵循了这个教程：https://assimpcy.readthedocs.io/en/latest/install.html

我下载了编译并安装的Assimp，下载了github repo of AssimpCy，但当我启动此程序时：

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

我得到这个错误：

你有什么想法可以帮上忙吗

Answer 1

我猜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'

试着用这个

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

所有公共包含都位于include/assimp文件夹中，并将以以下方式包含：

#include <assimp/types.h>

因此，将assimp前缀添加到include将为公共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。在Assimp安装过程中似乎出现了错误。我刚刚重新安装了Assimp并运行了python setup.py build_ext，它运行正常
