小编Dar*_*yan的帖子

我做了什么:

sudo -u postgres psql
CREATE ROLE shop CREATEDB LOGIN PASSWORD 'kurt1245';

然后我从GitHub克隆了一个存储库(一个使用pg的rails应用程序)bundle install,编辑database.yml来编写我的密码,现在在rake db:create(也setup和migrate)之后不起作用.

database.yml:

development: adapter: postgresql encoding: unicode database: shop_development pool: 5 username: shop password: kurt1245 test: adapter: postgresql encoding: unicode database: shop_test pool: 5 username: shop password: kurt1245

Idea的cmd和git bash看不到mvn命令。如果我将其用在Idea上，它将起作用：

但是在Idea的CMD或Bash中，我看到“ mvn：找不到命令”

为什么会这样？我将路径设置为C：\ Maven \ apache-maven-3.5.0 \ bin。在Linux上，它运作良好。

昨天不是这个错误.我没有对我的申请进行任何更改.刚睡觉了,现在我明白了.

错误:

home/dartnyan/.rvm/gems/ruby-2.3.0/gems/activerecord-4.2.6/lib/
active_record/connection_adapters/
postgresql_adapter.rb:651:in `initialize': could not connect to server:

database.yml的
