Cloudinary 变量在 .env 文件中不起作用

Question

我有一个使用 Express 后端 API 的 NextJs 应用程序。 我正在尝试将用户头像上传到 cloudinary 中的文件夹。 我有 cloudinar.js 文件和我从 userController 调用的 cloudinary.config 文件。 如果我直接在 cloudinary.config 文件中输入 cloud_name、api_key 和 api_secret，则它可以正常工作，但如果我将变量移至 .env 文件，并使用 process.env.CLOUD_NAME 调用它们，则会出现以下错误说我必须提供 cloud_name:

Error: Must supply api_key

我尝试了 String(process.env.CLOUD_NAME) 并收到了 cloud_name 被禁用的错误，但同样，如果我将云名称直接输入到配置对象中，它就可以工作。

我的 .enf 文件可以工作，因为它从 .env 文件获取 MONGO_URI

我正在 server.js 文件中初始化 dotenv： 从“dotenv”导入 dotenv；

dotenv.config();

这是cloudinar.js 文件：

import { v2 as cloudinary } from "cloudinary";

// Configuration
cloudinary.config({
  cloud_name: process.env.CLOUD_NAME,
  api_key: process.env.CLOUD_KEY,
  api_secret: process.env.CLOUD_SECRET, // Click 'View API Keys' above to copy your API secret
});

export default cloudinary;

这是 userController 中我称之为 cloudinary 的部分：

const result = await cloudinary.uploader.upload(image, {
      folder: "products",
      // width: 300,
      // crop: "scale"
    });

看起来这是一个范围问题，因此您应该能够通过在

cloudinar.js

中导入和配置 dotenv 来解决它
