Raiden failed to start becuase of sqlite3 missing

[reliveyy]

I follow the clean/install/start pattern and reproduce this raiden start failure more than once.

/tmp/raiden.log

It's related self-compiled Python3.7 in https://github.com/ExchangeUnion/xud-simnet/issues/73. The missing configure option --enable-loadable-sqlite-extensions leads to the error above.

P.S. A full Python3.7 compilation guide on Ubuntu 18.04

sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget libsqlite3-dev
wget https://www.python.org/ftp/python/3.7.7/Python-3.7.7.tgz
tar -xf Python-3.7.7.tgz
cd Python-3.7.7
./configure --enable-optimizations --enable-loadable-sqlite-extensions
make
sudo make altinstall
