leon update --develop fixed it somehow

[louistiti]

For people having such issue, you can try the following:

npm install --global @leon-ai/cli@beta
leon create birth --develop
leon start

This will help you to use the 1.0.0-beta.8+dev version which uses compiled binaries, so there is no need to have a Python environment at runtime.

We are going to release the beta version 8 in the coming days.

Closing this issue as it has been solved.
