使用master分支安装paperboy https://github.com/timkpaine/paperboy.git

git clone https://github.com/timkpaine/paperboy.git
cd paperboy
conda create --name python3.7 python=3.7
conda activate python3.7
npm install
npm run build
pip install -e .

然后打开

paperboy/server/deploy_nix.py

用2更改行号

from six import iteritems #from gunicorn.six import iteritems

然后运行

python -m paperboy
