javascript - 在 Node.js 中安装 Postgres 模块时出错以及其他 2 个 node.js 问题

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”时都会收到以下错误:

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。有什么想法吗？

另外我应该提到我已经安装了 Python 2.7.3。

Answer 1

您使用的是 Windows:

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

所以我建议您获取 pg 模块的预构建二进制文件。在 Windows 上编译东西……很有趣。

直接的错误是 pg_config 可执行文件不在 PATH 上，但在您修复它之后会有更多错误。获取预构建的可执行文件，除非您计划踏上探索之旅。
