ModuleNotFoundError:搅拌机上没有名为“OpenEXR”的模块

Question

我试图在OpenEXR脚本上使用blender's 3.1.2模块，但无法导入它。我可以使用我安装的python 3.8.10导入它。

我首先使用以下方法安装它：

pip install openexr

pip3 install openexr

sudo apt install libopenexr-dev

而且它在我的python 3.8.10命令行上运行得很好。

然后我尝试使用搅拌器的python版本来安装它：

./python3.10 -m pip install openexr

但是我从gcc那里得到了这个错误：

有什么办法可以解决这个问题，这样我就可以在搅拌机上使用OpenEXR，或者让搅拌器使用安装的python来代替它自己的版本？

我上的是ubuntu 20.04

Answer 1

最后，我将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。

1-从OpenEXR-1.3.8下载这里。

2-将所有文件复制到您的搅拌器python可执行文件中，对我来说是：/homa/jros/Downloads/blender-2.90.0-linux64/2.90/python/bin。

3-使用这些参数-m setup.py install运行可执行文件，如下

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

而且它应该能工作。您可能还需要安装这些设备：

sudo apt install python3.10-dev
pip install openexr
pip3 install openexr
sudo apt install libopenexr-dev
