未找到 REACT 模块：无法解析 '../http-common'

Question

我发现了这个错误：

"Module not found: Can't resolve '../http-common'" 当启动 react 项目时

我已经尝试删除 package-lock.json 和 node-modules 文件夹，运行 npm install 然后再次 npm start

但它不起作用，编译失败

import React from 'react';
import http from "../http-common";

class PersonnageDataService{
    getAll(){
        return http.get("/personnages");
    }

    get(id){
        return http.get(`/personnages/${id}`);
    }

    create(data){
        return http.post("/personnages", data);
    }

    update(id, data){
        return http.put(`/personnages/${id}`, data);
    }

    delete(id){
        return http.delete(`/personnages/${id}`);
    }

    deleteAll(){
        return http.delete(`/personnages`);
    }

}

export default new PersonnageDataService();

这是我的 package.json 文件

{
  "name": "mearnclient",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.11.5",

  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

你有什么解决办法吗？

Answer 1

如果 http-common 是在您的项目之外定义的模块，您应该将其引用为“http-common”并在 package.json 中的依赖项中声明它。

如果 http-common 是项目中的 js 文件，则它应该在 PersonnageDataService 的父文件夹中可用。示例：如果 PersonnageDataService 在 src/services/ 中，那么您需要在 src 中添加一个 http-common.js。
