installation fails

[romainGuiet]

Hi @haesleinhuepf , Hi team !

I'm trying to install devbio-napari using this env_devbio.yml :

name: "devbio"
channels:
  - conda-forge
  - pytorch
dependencies:
  - napari=0.4.19
  - python=3.9
  - devbio-napari=0.10.1
  - pyqt
prefix: "/opt/conda/envs/devbio"

and this line conda env update -n devbio -f /tmp/env_devbio.yml (I'm using conda but it uses the LibMambaSolver now, so it should be fine)

RUN conda env update -n devbio -f /tmp/env_devbio.yml     && conda clean --all -f -y     && conda env export -n "biop"      && rm /tmp/env_devbio.yml:

261.4 Could not solve for environment specs
261.4 The following packages are incompatible
261.4 ├─ devbio-napari 0.10.1**  is installable with the potential options
261.4 │  ├─ devbio-napari 0.10.1 would require
261.4 │  │  └─ npe2 <0.7.0 , which can be installed;
261.4 │  ├─ devbio-napari 0.10.1 would require
261.4 │  │  └─ __osx, which is missing on the system;

261.4 │     └─ __win, which is missing on the system;
261.4 └─ napari 0.4.19**  is not installable because it requires
261.4    └─ npe2 >=0.7.2 , which conflicts with any installable versions previously reported.

from the error message I guess it would pass on Mac and Win and fails on linux because :

261.4 │  ├─ devbio-napari 0.10.1 would require
261.4 │  │  └─ npe2 <0.7.0 , which can be installed;

and

261.4 └─ napari 0.4.19**  is not installable because it requires
261.4    └─ npe2 >=0.7.2 , which conflicts with any installable versions previously reported.

I tried to :

• add the "default" to the channels (doesn't work better)
• remove the version of napari, the build works but napari doesn't start as it's complaining about qt being installed but not working (see below)

thank you in advance for your suggestions,

Best
