ModulenotFoundError：No模块名为＆＃x27; OpenExr＆＃x27;在搅拌机上

Question

我正在尝试在Blender的3.1.2脚本上使用OpenExr模块，但我无法导入。我可以使用安装的Python 3.8.10导入它。

我首先使用以下方式安装它：

pip install openexr

pip3 install openexr

sudo apt install libopenexr-dev

它在我的Python 3.8.10命令行上正常工作。

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：

我终于通过将文件从OpenExr-1.3.8复制到Python可执行文件的文件夹，然后安装OpenExr来使其工作。

1-下载OpenEXR-1.3.8来自在这里。

2-将所有文件复制到您的Blender Python可执行文件中，对我来说是：
/homa/jros/downloads/blender-2.90.0.0.0-linux64/2.90/python/bin/bin

3-使用这些参数可执行可执行

./python3.7m -m setup.py install

它应该起作用。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
