Ruby on rails rake db：设置->；雷克流产了！Errno:：eNote:没有这样的文件或目录-标识

我正试图在一个现有的RubyonRails项目上安装，但是我在PostgresDB安装上挂断了。我使用RVM使用ruby 2.1.2来设置项目。使用以下命令使用自制软件安装pg gem：

gem install pg -- --with-pg_config=/usr/local/bin/pg_config

我的database.yml文件如下所示：

development:
  adapter: postgresql
  encoding: unicode
  database: myapp_development
  pool: 5
  username: myusername
  password: 

test:
  adapter: postgresql
  encoding: unicode
  database: myapp_test
  pool: 5
  username: myusername
  password: 

我安装了我所有的宝石

我使用以下方法手动启动postgres服务器：

pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

日志文件输出以下内容：

ERROR:  database "myapp_development" already exists
STATEMENT:  CREATE DATABASE "musictown_development" ENCODING = 'unicode'
ERROR:  database "myapp_test" already exists
STATEMENT:  CREATE DATABASE "musictown_test" ENCODING = 'unicode'

或者，我使用postgresapp启动服务器

当我运行rake db:setup时，我得到以下结果：

myapp_development already exists
myapp_test already exists

它会创建一组表和索引，然后在到达此处时停止：

也许gemfile中的一颗宝石有问题

---

这个问题有点类似：。可能某些gem版本错误？

若要修复此问题，请从以下位置安装ImageMagick CLI工具：，Mac OS二进制版本。使用MacPorts安装，这会将路径添加到my.bash_配置文件中。现在rake db:setup命令可以找到ImageMagick，并且可以工作。

问题不是PostgreSQL，而是通过CarrierWave的Minimagik

是ImageMagick的一部分，您的

路径中似乎没有它。我仍然有点不清楚我应该做什么。我应该向bash_配置文件添加什么路径？
