我试图在blender's 3.1.2脚本上使用OpenEXR模块，但我无法导入它。我可以使用我安装的python 3.8.10来导入它。
我首先安装它使用:
pip install openexr
pip3 install openexr
sudo apt install libopenexr-dev
它在我的python 3.8.10命令行上工作得很好。
然后我尝试使用blender的python版本安装它:
./python3.10 -m pip install openexr
但是我从gcc:

有什么办法解决这个问题，这样我就可以在blender上使用OpenEXR，或者让blender使用python安装而不是它自己的版本?
我在ubuntu 20.04
通过将OpenEXR-1.3.8中的文件复制到python可执行文件的文件夹中，然后安装OpenEXR，最终使其工作。
1-从这里下载OpenEXR-1.3.8。
2-将所有文件复制到你的blender python可执行文件中，对我来说它是:/homa/jros/Downloads/blender-2.90.0-linux64/2.90/python/bin
3-使用-m setup.py install参数运行可执行文件，如下所示
./python3.7m -m setup.py install
，它应该可以工作。您可能还需要安装这些:
sudo apt install python3.10-dev
pip install openexr
pip3 install openexr
sudo apt install libopenexr-dev
