【Umi 四】 Cannot find module 'umi'

1、前序

安装完成 @umijs/preset-react,且配置好config.js之后,重新启动项目,报错 Cannot find module 'umi'

// package.json
{
  "name": "myumi2",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "umi dev",
    "build": "umi build"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "antd": "^4.7.3",
    "umi": "^3.2.24"
  },
  "devDependencies": {
    "@umijs/preset-react": "^1.6.15"
  }
}
// config/config.js
export default {
     antd: {}
}

2、问题

Cannot find module 'umi'

已经全局安装过 umi ,但是还是报错

3、解决方案

在当前目录下执行 yarn add umi 或 npm i umi

(一般情况下,包管理器只在当前目录下的 node_modules 文件夹下查找所依赖的库,如果文件夹下没有,也不会去系统全局查找。)

 4、修改后

// package.json
{
  "name": "myumi2",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "umi dev",
    "build": "umi build"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "antd": "^4.7.3",
    "umi": "^3.2.24"
  },
  "devDependencies": {
    "@umijs/preset-react": "^1.6.15"
  }
}
