问题
I have successfully installed openexr using pip install openexr on my mac, but the same command fails on Ubuntu:
OpenEXR.cpp:9:22: fatal error: ImathBox.h: No such file or directory
  compilation terminated.
  error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

  Failed building wheel for openex
I tried using apt-get install openexr which seems like to install without an error but then when I try to import OpenEXR in python, it doesn't work. 
Does anyone know why?
回答1:
You need to install the apt package "libopenexr-dev" this will resolve the pip issue.
I didn't have this issue on the mac, a "brew install openexr" must've installed the headers also.
回答2:
openexr is only the c++ implementation. You need the py-openexr to be able to use in python. You can find how to install on this link

You first need to install zlib by:
$ sudo apt-get install zlib1g-dev

I installed in Ubuntu 16.04 by doing the following commands:
sudo apt-get install libopenexr-dev
sudo apt-get install openexr
sudo apt-get install python3-dev
pip install OpenEXR --user
