在 Node.js 和 2 个其他 node.js 问题中安装 Postgres 模块时出错

Question

我在为 Node.js 安装 Postgres 数据库模块时遇到问题，每次运行命令“npm install pg”时都会出现以下错误：
C:>npm install pg
npm http GET https://registry.npmjs.org/pg
npm http 200 https://registry.npmjs.org/pg
npm http GET https://registry.npmjs.org/pg/-/pg-0.12.1.tgz

npm http GET https://registry.npmjs.org/generic-pool/2.0.2
npm http 200 https://registry.npmjs.org/generic-pool/2.0.2
npm http GET https://registry.npmjs.org/generic-pool/-/generic-pool-2.0.2.tgz
npm http 200 https://registry.npmjs.org/generic-pool/-/generic-pool-2.0.2.tgz

node-gyp rebuild || (exit 0)

这个错误发生在我的工作机器（linux/windows box）和我家里的个人机器（windows）上。有任何想法吗？

另外我应该提到我已经安装了 Python 2.7.3。

Answer 1

您在 Windows 上：

'pg_config' is not recognized as an internal or external command, operable program or batch file.

所以我建议你得到一个预先构建的 pg 模块的二进制文件。在 Windows 上编译东西是......很有趣。

直接错误是pg_config可执行文件不在PATH. 获取预构建的可执行文件，除非您计划踏上探索之旅和发誓之旅。
