VSCode安装Prettier时执行npm install遇MODULE_NOT_FOUND错误求助

问题背景 #

执行npm install时出现如下错误，提示找不到readable-stream模块：

PS C:\Users\ytrip\OneDrive\Desktop\javascript-essential-training-2832077-main> npm install
node:internal/modules/cjs/loader:364
      const err = new Error(
                  ^

Error: Cannot find module 'C:\Program Files\nodejs\node_modules\npm\node_modules\are-we-there-yet\node_modules\readable-stream\readable.js'. Please verify that the package.json has a valid "main" entry

  requestPath: 'readable-stream'
}

项目的package.json内容如下：

{
  "name": "javascript-essential-training-exercise-files",
  "version": "1.0.0",
  "description": "Repository for exercise files used in the LinkedIn Learning course `JavaScript Essential Training` instructed by Morten Rand-Hendriksen and published 2020.",
  "main": "index.html",

  "license": "SEE LICENSE IN LICENSE",
  "devDependencies": {
    "eslint": "^7.11.0",
    "eslint-config-standard": "^14.1.1",
    "eslint-plugin-import": "^2.22.0",
    "eslint-plugin-node": "^11.1.0",
    "eslint-plugin-promise": "^4.2.1",
    "eslint-plugin-standard": "^4.0.1",
    "prettier": "^2.1.2"
  }
}

问题原因 #

错误路径指向C:\Program Files\nodejs\node_modules\npm下的依赖，说明是npm自身的内置依赖损坏，和项目的依赖配置无关。

修复步骤 #

1. 清理npm缓存：

   npm cache clean --force
   

2. 重新安装最新版npm：

   npm install -g npm@latest
   

3. 如果上述命令仍报错，直接下载最新LTS版本的Node.js安装包覆盖安装，这会自动修复npm及其所有内置依赖。
4. 回到练习文件夹，删除node_modules文件夹和package-lock.json文件，然后重新执行：

   npm install
