yarn install
Actually, some packages, such as spatial-index, only work with Python version <= 3.8. Therefore, you will need a specific version of Python by following these steps:
conda create -n myenv python=3.8
conda activate myenv
We assume here a standard Anaconda Python 3 package has been already installed. You then need to perform the following addition steps:
conda install sqlparse
conda install -c conda-forge healpy pyvo
pip install -r requirements.txt
pip install https://github.com/edoardoted99/xnicer_dev.git
yarn run build
python3 py/main.py
then, go to localhost on 8080 port.
