我的版本如下：

c:\>npm -v

当我检查存储库并尝试 node-gyp rebuild 时，我收到以下错误消息：

【问题讨论】：

回答我自己的问题，这只是在尝试 npm install pg 之前没有安装 PostgreSQL 的结果。此外，pg_config 必须在您的系统路径中。

标签： windows node.js postgresql npm

【解决方案1】：

在 OSx 上，请参阅 Peter Lyons 的回答（已接受）。 Xcode 版本选项对我有用。 https://stackoverflow.com/a/12825911/296765

【解决方案2】：

每行

'pg_config' is not recognized as an internal or external command

我只需要在尝试之前安装 PostgreSQL

npm install pg

【讨论】：

Note) 在 Windows 8.1 上我无法让 pg_env.bat 提交对环境变量的更改，所以我不得不手动添加它们。可以在版本后的根文件夹中找到（C:\Program Files\PostgreSQL\9.3\pg_env.bat）
缺少C:\Program Files\PostgreSQL\9.3\bin的路径

【解决方案3】：

您是否查看过 node-gyp 的安装说明？

https://github.com/TooTallNate/node-gyp#installation

我最近在 Windows 上遇到了 node-gyp 的问题，同时尝试安装依赖它的单独模块。确保您已安装所需的每个项目。具体注意这部分：

对于节点和本机模块的 64 位版本，您还需要 Windows 7 64 位 SDK 如果安装失败，请尝试卸载您首先安装的任何 C++ 2010 x64&x86 Redistributable。

【讨论】：

我使用的是 32 位，但作为预防措施，我重新安装了 C++ 2010（和 SP1）。这个错误原来只是由于在尝试“npm install pg”之前没有安装 PostgreSQL（并将 pg_config 放在系统路径中）。
@i3enhamin 啊，您可以回答自己的问题并接受它，以便将来看到此页面的任何人都可以轻松知道该怎么做。
