Windows Enterprise 2016 LTSB Version 1607. Installed Wiki.js with PostgreSQL. Has Node.js installed previously (v12.16.2).

Got to step 8 of wiki.js installation process using the Powershell:

I receive this error:

I realize that I forgot to create a PostgreSQL, so I used pgAdmin4.28 to create a "wiki" database. Error now changed to:

I had similar issue with postgres and wiki.js. Solution was to manually create the Database in postgres, BEFORE you run node server:

CREATE DATABASE wiki

Hope that saves you the time I had to spend to figure this out.

My environment is as follows: Windows 10 professional version number 20h2 node version v14.15.4 PostgreSQL V 13.1, the error content is as follows:

You just need to config.yml The database configuration in is modified as follows:

db:
  type: postgres

  # PostgreSQL / MySQL / MariaDB / MS SQL Server only:
  host: localhost
  port: 5432
  user: postgres #YOU PostgreSQL USERNAME
  pass: willasas@wiki. #YOU PostgreSQL PASSWORD
  db: wiki #YOU DATABASE NAME
  ssl: false

Then run the code

node server

And type in the address bar of your browser http://127.0.0.1 : 3000 / parallel return

After a couple hours of testing I realized some problems using postgres in wiki.js. These are some recommendations you can try in config.yml:

db:
  type: postgres
  
  # if you are using docker try using IP instead of localhost
  host: localhost
  port: 5432
  
  # don't use _ here. It'll cause connection error undefined.
  user: wikijs
  
  # start with letter, if you start with @ it will throw an error.
  # I used a 18 long pass without any problem. Ex:
  pass: wiki@projectW777!@
  
  # you can use _ here. Ex:
  db: prj_wiki

If you need to change the database password, this can help you:

ALTER USER postgres WITH PASSWORD 'xxx';

Solution 5:[5]

Use this docker-compose file.

It solved my problems. Also make sure all the service names are unique, i.e. neither of the exist in your presently running docker containers

version: '3'
services:
  db:
    image: mysql:8.0
    logging:
      driver: "none"
    restart: unless-stopped
    volumes:
      - db-data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: mysql123!
      MYSQL_DATABASE: wiki

  wiki:
    image: requarks/wiki:2
    depends_on:
      - db
    environment:
      DB_TYPE: mysql
      DB_HOST: db
      DB_PORT: 3307
      DB_USER: root
      DB_PASS: mysql123!
      DB_NAME: wiki
    restart: unless-stopped
