所有 CommonJS 模块中都可用的动态 import()

Question

当我尝试运行

npm install

时，出现以下错误。错误信息：

taskRepository: Failed to require task module for setTimestamp: require() of ES Module ......\node_modules\dateformat\lib\dateformat.js from .....\setTimestamp.js not 
supported.
Instead change the require of dateformat.js in .....\setTimestamp.js to a dynamic import() which is available in all CommonJS modules.

在 setTimestamp.js 文件中，我们有

const stringReplacer = require("@ui5/builder").processors.stringReplacer;
const df = require("dateformat");

这是一个基于 SAPUI5 的云应用程序，我们有 2 个 package.json 文件。 在根文件夹下：

我尝试使用以下方法解决此问题：

npm i [email protected]

或者，在 package.json 文件中，写入

"type": "module"

等。 参考：将 index.js 的要求更改为动态 import()，该方法在所有 CommonJS 模块中都可用

有人可以帮我解决这个错误吗？任何帮助将不胜感激。 要求：请不要关闭问题。我知道这是重复的问题，但是我找不到任何解决方案，尝试了我找到的东西。谢谢

Answer 1

我遇到了同样的错误，需要

node-fetch

。解决方案是

const fetch = (...args) => import('node-fetch').then(({default: fetch}) => fetch(...args));

Answer 2

使用nodemon

1. 如果未安装请安装nodemon
2. 在根目录创建nodemon.json文件
3. nodemon.json 文件应包含一个具有用于环境的变量名称的对象。 （即{“env”：{“enviornment_variable1”：“somevalue”，“environment_varialbe2”：“somevalue”}}）；
4. 通过 process.env.environment_variable 使用环境变量。
5. 确保重新启动服务器
