我正在尝试在 rails 项目的现有 ruby 上进行设置，但在 postgres 数据库设置上挂断了。我使用 RVM 通过 ruby 2.1.2 设置项目。使用以下命令使用自制程序安装 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

adapter: postgresql
encoding: unicode
database: myapp_test

我手动启动了 postgres 服务器：
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
日志文件输出如下：
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 耙 db:setup 我得到这个：
myapp_development already exists
myapp_test already exists
它创建了一堆表和索引，然后当它到达这里时就停止了：

可能 gem 文件中的 gem 之一有问题？
这个问题有点类似：Carrierwave, Rails 4; Errno::ENOENT (No such file or directory - identify)。也许某些 gem 是错误的版本？
要解决此问题，请从此处安装 ImageMagick CLI 工具：imagemagick.org/script/binary-releases.php、Mac OS 二进制版本。使用 MacPorts 安装，这会将路径添加到我的 .bash_profile 文件中。现在 rake db:setup 命令能够找到 ImageMagick，并且可以工作。
