Error happened when running the demo

[flyq]

ENV

Ubuntu 18.04 in VMware

$ rustc --version
rustc 1.42.0 (b8cedc004 2020-03-09)

steps

follow the README.md:

1. install postgres
2. install diesel_cli(to make it succeed, I install mysql, libsqlite3-dev and so on)
3. modify the Cargo.toml:

[features]
cockroach = []
mysql = []
postgres = []
sqlite = []
default = ["postgres"]

4. modify the .env
   I JUST modify the DATABASE_URL to postgres link.
5. diesel migration run
   it succeeds
6. run:

cargo run

Problem

What should I do to just use postgres? Because I think problem is caused by the program trying to connect other database like mysql, redis and so on:

I've got it working with sqlite with no other databases. I did however need to install redis: apt-get install redis-server

The error appears to be looking for a MySQL connection.. maybe double check the postgres entry in the .env, maybe run a 'cargo build' before the 'cargo run' too.

Hope this helps
