Question

我在SQlite和MySQL上使用过rails。第一次使用PostgreSQL。刚刚在我的本地机器上安装了PostgreSQL。使用Heroku进行制作。

每次我运行rake db：migrate 或 rake db：create 我都会收到以下错误：

PG::ConnectionBad: fe_sendauth: no password supplied

我用Homebrew安装了PostgreSQL，但从未设置用户或密码。这是我的Postgres设置：

这是我的database.yml文件

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
default: &default
  adapter: sqlite3
  pool: 5
  timeout: 5000

development:
  adapter: postgresql
  encoding: unicode
  database: "mydatabase"


# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/test.sqlite3

production:
  adapter: postgresql
  encoding: unicode
  url: "HEROKU URL"

以下是我从中获取的pg_hba.conf的设置 - cd / usr / local / var / postgres / - 打开pg_hba.conf

我错过了什么？

在编辑器中打开文件/Library/PostgreSQL/9.6/data/pg_hba.conf。确保USER和METHOD的值匹配以下示例（所有和信任）。

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust

保存文件，然后从终端运行pg_ctl reload -D /Library/PostgreSQL/9.6/data。
