Omero.web installation issue

I would like to use omero-figure and, for that, I will need to install omero-web. Unfortunately, I couldn’t install it on my Mac or on a Windows 7 computer. I have tried to follow the most simple instructions (in comand prompt) as well as the video on YouTube (in conda) but, regardless of the way I try to do it, I seem to have the same error, I believe.

To make it easier to follow my issue, I followed this video step-by-step omero-web developer install - YouTube

And after going through half of the video (after going to Visual Code, that’s where I started to have problems…)

This is part of the error that I get after I run % pip install -e .on visual studio code:

→ this is where the code gets stuck at first:

Building wheels for collected packages: zeroc-ice
  Building wheel for zeroc-ice ( ... - 

…after this, the code runs but it gives me the following error

  2 errors generated.
  error: command '/usr/bin/gcc' failed with exit code 1
  ERROR: Failed building wheel for zeroc-ice
  Running clean for zeroc-ice

I have installed the requirements (ICE included) but I need having the same error…

What could be causing this issue?

Many thanks!

Hi @Debora_Serrenho,

do you mind if I convert this to a public topic so others can follow along?

Please do! Thanks

The installation is trying to compile the Python support for Ice. What platform is this? We might have pre-compiled wheels that you can use. See Open Microscopy Environment · GitHub, e.g.

pip install

If not, then I’d suggest trying conda:

All the best,

I solved this problem! It was a simple thing actually. I was having troubles setting the environment variable!

I was using conda but, since I am not familiar with this sort of things, I was having an hard time setting the environment variable on my Mac.
Thanks for the help anyway. I would ask whether this section of the installation instructions could be clarified in git-hub. It could help other people in a similar situation to mine. Regardless of that, thanks for the help!
