运行时遇到问题：

rake db:create:all

我目前有：

$ psql --version
psql (PostgreSQL) 9.3.0

$ which psql
/Applications/Postgres.app/Contents/MacOS/bin/psql

并得到：

$ rake db:create:all
could not connect to server: Permission denied
    Is the server running locally and accepting
    connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

尝试卸载并重新安装pggem，但仍然无法正常工作。

首先尝试关注 Ryan Bates 截屏但遇到了一些问题，然后检查了建议设置此路径的 Heroku Postgres：

PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"

可能是 rake 正在尝试连接，/var/pgsql_socket/.s.PGSQL.5432但域套接字实际上在其他地方。我的是在/tmp/.s.PGSQL.5432。你可以试试这些：

host: localhost在您的 database.yml 中指定。例如：

development:
  host: localhost
  # other stuff

或者

在实际居住/var/pgsql_socket/的地方创建一个符号链接。.s.PGSQL.5432

mkdir /var/pgsql_socket
ln -s /tmp/.s.PGSQL.5432 /var/pgsql_socket/.s.PGSQL.5432

您可能还必须 chown 和 chmod 链接。我不确定您是否还必须链接 .s.PGSQL.5432.lock 。

第一个选项要容易得多。不确定是否其中一个更好。
