Node.js Webpack bundle enoint:没有此类文件或目录fs.readdirSync

我们希望创建在AWS Lambda上运行的微型应用程序。我们正在为此调查Webpack2。但是，我们有一个遗留代码，它使用

fs.readdirSync

获取文件/模块名称列表，以生成模块列表。执行捆绑包时，我们得到一个错误

error:enoint:没有这样的文件或目录，scandir'/innerLib'

，因为webpack不知道执行

fs.readdirSync（path.resolve（u dirname，'innerLib'）在文件
lib/lib.js
中，并在绑定期间解析文件名数组

在不对遗留代码进行重大更改的情况下，我们可以采用哪些方法处理wepback。我在下面和后面都有一个简单的例子

webpack.config.js

var path = require( 'path' );
var webpack = require( 'webpack' );

module.exports = {
  context: __dirname,
  entry: ['./index.js'],
  output: {
    filename: 'bundle.js',
  },
  target: 'node',
}

const  lib = require('./lib/lib.js');

lib.getModuleList((err, modules) => console.log(modules));

const fs = require('fs');
const path = require('path');
let moduleList = [];
let list = fs.readdirSync(path.resolve(__dirname, 'innerLib'));

exports.getModuleList = getModuleList;

function getModuleList(callback) {
  return callback(null, moduleList);
}

list.forEach(filename => {
  moduleList.push({
    name: filename
  });
});

console.log('a lib loaded');

console.log('b lib loaded');

index.js

var path = require( 'path' );
var webpack = require( 'webpack' );

module.exports = {
  context: __dirname,
  entry: ['./index.js'],
  output: {
    filename: 'bundle.js',
  },
  target: 'node',
}

const  lib = require('./lib/lib.js');

lib.getModuleList((err, modules) => console.log(modules));

const fs = require('fs');
const path = require('path');
let moduleList = [];
let list = fs.readdirSync(path.resolve(__dirname, 'innerLib'));

exports.getModuleList = getModuleList;

function getModuleList(callback) {
  return callback(null, moduleList);
}

list.forEach(filename => {
  moduleList.push({
    name: filename
  });
});

console.log('a lib loaded');

console.log('b lib loaded');

lib/lib.js

var path = require( 'path' );
var webpack = require( 'webpack' );

module.exports = {
  context: __dirname,
  entry: ['./index.js'],
  output: {
    filename: 'bundle.js',
  },
  target: 'node',
}

const  lib = require('./lib/lib.js');

lib.getModuleList((err, modules) => console.log(modules));

const fs = require('fs');
const path = require('path');
let moduleList = [];
let list = fs.readdirSync(path.resolve(__dirname, 'innerLib'));

exports.getModuleList = getModuleList;

function getModuleList(callback) {
  return callback(null, moduleList);
}

list.forEach(filename => {
  moduleList.push({
    name: filename
  });
});

console.log('a lib loaded');

console.log('b lib loaded');

lib/innerLib/a.js

var path = require( 'path' );
var webpack = require( 'webpack' );

module.exports = {
  context: __dirname,
  entry: ['./index.js'],
  output: {
    filename: 'bundle.js',
  },
  target: 'node',
}

const  lib = require('./lib/lib.js');

lib.getModuleList((err, modules) => console.log(modules));

const fs = require('fs');
const path = require('path');
let moduleList = [];
let list = fs.readdirSync(path.resolve(__dirname, 'innerLib'));

exports.getModuleList = getModuleList;

function getModuleList(callback) {
  return callback(null, moduleList);
}

list.forEach(filename => {
  moduleList.push({
    name: filename
  });
});

console.log('a lib loaded');

console.log('b lib loaded');

lib/innerLib/b.js

var path = require( 'path' );
var webpack = require( 'webpack' );

module.exports = {
  context: __dirname,
  entry: ['./index.js'],
  output: {
    filename: 'bundle.js',
  },
  target: 'node',
}

const  lib = require('./lib/lib.js');

lib.getModuleList((err, modules) => console.log(modules));

const fs = require('fs');
const path = require('path');
let moduleList = [];
let list = fs.readdirSync(path.resolve(__dirname, 'innerLib'));

exports.getModuleList = getModuleList;

function getModuleList(callback) {
  return callback(null, moduleList);
}

list.forEach(filename => {
  moduleList.push({
    name: filename
  });
});

console.log('a lib loaded');

console.log('b lib loaded');

您的问题是
\uu dirname
正在解析为
/
。要使其与webpack一起工作，请设置：

node: {
  __dirname: true
}

在您的webpack.config.js中。添加后，您的捆绑包对我来说执行得很好。
您是如何执行捆绑包的？您是一个实时保护程序，谢谢！
