Kaleido v1+ requires Google Chrome to be installed.

[erfanshekarriz]

Hi team,

A bug that arises with the new version of Kaleido that I wanted to bring to your attention.

The error occurs because MetaCerberus installs Kaleido v1+ to export SVG charts, but this newer version of Kaleido no longer includes a built-in Chromium browser. The default conda environment built from your documentation lacks the required Google Chrome/Chromium installation.

I recommend putting kaleido v0.2.1 as one of your dependencies for the conda recipe.

I explicitly put python-kaleido=0.2.1 in my conda installation line and it fixed the issue.

Here is the full error:
