node.js - 为什么我无法在 Mac 上安装 PostGreSQL？

Question

我尝试在 Mac (Mac OS 10.6.8 Snow Leopard) 上安装 PostGreSQL，但不断收到此错误:

$ npm install pg
npm http GET https://registry.npmjs.org/pg
npm http 304 https://registry.npmjs.org/pg
npm http GET https://registry.npmjs.org/generic-pool/1.0.7
npm http 304 https://registry.npmjs.org/generic-pool/1.0.7

> pg@0.6.9 install /Users/omegatai/node_modules/pg
> node-waf configure build || (exit 0)

什么是 pg_config？我该如何解决这个问题？谢谢!

Answer 1

pg_config程序通常作为 PostgreSQL 服务器安装的一部分进行安装。另一方面，您似乎正在安装一个客户端库，该库期望已安装服务器。

前往http://www.postgresql.org/并首先安装 PostgreSQL服务器。
