node.js 项目找不到 swagger-ui-express 模块

Question

在我的 app.js 文件中，我调用 swagger-ui 作为项目的一部分：

const swaggerUI = require("swagger-ui-express");
const YAML = require("yamljs");
const swaggerDocument = YAML.load("./swagger.yaml");

app.use(
  "/swagger",
  swaggerUI.serve,swaggerUI.setup(swaggerDocument)
);

当尝试使用 docker compose 运行项目时，我收到此错误：

虽然 swagger-express-ui 是使用 npm 下载的，但我收到这些错误，我能做些什么来修复它？

Answer 1

我通过运行解决了这个问题

npm install

似乎解决了问题

Answer 2

您必须在 docker 服务器上安装“swagger-ui-express”。您可以使用以下命令：

npm i swagger-ui-express
