安装 pg-native 依赖项时出现问题

Question

我目前正在努力将 pg-native 依赖项安装到我的项目文件夹中。 当我尝试运行我的index.js时，它说它无法“解决依赖关系pg-native”，尽管我不相信我调用它。 但是，假设我这样做了，我尝试安装依赖项并在尝试执行以下操作时收到此错误屏幕：

C:\Users\jmurr\Documents\MSDPP-Map>npm i pg-native

在安装之前，我已尽力正确设置所有内容，如 Windows 部分所述：https://www.npmjs.com/package/pg-native。 然而，它仍然不起作用。 我可能做错了其中一件事，希望这里有人可以帮助我解决过去几天试图解决这个问题的挫败感。 谢谢您的宝贵时间！

我遇到了同样的问题，我按照 https://www.npmjs.com/package/pg-native 中的步骤进行操作；假设您根据错误消息使用的是 Windows，但还需要安装 python。

对于我来说，这是我遵循的具体步骤：

1. 从 https://www.python.org/downloads/

   下载并安装 Python

2. 从https://visualstudio.microsoft.com/downloads/

   下载并安装 Visual Studio 2022 Community Edition（使用 c++ 安装桌面开发，保留默认值）

3. 从 http://www.postgresql.org/download/windows/

   下载并安装 Postgres

4. 将

   C:\Program Files\PostgreSQL\16\bin

   添加到路径中。请记住重新打开您已经打开的任何命令提示符，否则您可能会继续收到有关缺少组件的错误，例如

   pg_config

   ，这来自 Postgres bin 文件夹。

5. 满足上述所有条件后，您应该能够毫无问题地安装

   pg-native

   。
