没有找不到模块'fs'：我已经尝试了所有可用的链接来解决这个问题

Question

我正在尝试使用 unlink 功能从本地系统中删除文件。但出现找不到模块“fs”的错误。以下是为您提供一些见解的文件。 在我的

app.component.ts

import * as fs from 'fs';
export class Component {
 var filepath = 'C:/Users/[username]/Downloads/test.txt';
 fs.unlink(filepath);

}

但是给出了找不到模块'fs'的错误

 webpack.config.js

 var path = require("path")
 const nodeExternals = require('webpack-node-externals');
 var webpack = require('webpack');

 module.exports = {
"entry": "./lib/index.js"
 ,   "output": {
    "path": __dirname + "/build"
 ,  "filename": "xxhash.js"
 ,  "library": "XXH"
 ,  "libraryTarget": "umd"
 }
 ,   "target": "node"

 ,"node": {
  "fs": "empty",
 }  
 ,    "externals":{
        "fs":    "commonjs fs",
        "path":  "commonjs path"
    }
    }

我在 webpack.config.js 中添加了一行

  var path = require("path")
  const nodeExternals = require('webpack-node-externals');//added
  var webpack = require('webpack');//added

   module.exports = {
  "entry": "./lib/index.js"
  ,   "output": {
    "path": __dirname + "/build"
   ,    "filename": "xxhash.js"
  , "library": "XXH"
    ,   "libraryTarget": "umd"
    }
  ,   "target": "node"     //added

   ,"node": {         //added
  "fs": "empty",
    }   
   ,      "externals":{           //added
        "fs":    "commonjs fs",
        "path":  "commonjs path"
      }
     }

我参考的链接：

Cannot find module 'fs'

Answer 1

使用文件系统 npm 模块进行文件系统使用 fs 模块似乎已被弃用。

npm install file-system --save

import * as fs from 'file-system';

希望它会起作用！
