Question

我正在尝试将我的webpack conf从v1.13更新到3.5但我不能，我不知道有什么问题，我一直在关注此链接（https://webpack.js.org/guides/migrating/）但我仍然有错误

webpack.server.js

var fs = require('fs');
var path = require('path');
var webpack = require('webpack');
var deepmerge = require('deepmerge');
var webpackCommonConfig = require('./webpack.common');

var nodeModules = {};
fs.readdirSync('node_modules')
  .filter(function(x) {
    return ['.bin'].indexOf(x) === -1;
  })
  .forEach(function(mod) {
    nodeModules[mod] = 'commonjs ' + mod;
  });

var sourceMapSupportModule = "require('source-map-support').install({environment: 'node'});\n\n";

var output = { path: path.join(process.cwd(), 'tmp'), filename: 'bundle.js' };

if (process.env.NO_OUTPUT_PATH) {
  output = { filename: 'server.js' };
}

var debug = false;
if (process.env.DEBUG_MODE) {
  console.log('THIS IS DEBUG MODE');
  debug = true;
}

var loaders = webpackCommonConfig.module.loaders.concat();
loaders.push({ test: /\.scss$/, loader: 'null-loader' });

delete webpackCommonConfig.module;

webpack.common.js

      "public",
      "node_modules"

    extensions: [".json", ".js"]

的package.json

"dev": "rimraf tmp && concurrently --kill-others \"npm run watch-build-server\" \"npm run hot:client\" \"npm run dev:server:wait\"",
"watch-build-server": "run-s clean:tmp hot:server",
"hot:client": "cross-env NODE_ENV=development EXTRACT_TEXT_PLUGIN=false webpack-dev-server --config tools/webpack.client.js",
"dev:server:wait": "just-wait -p \"tmp/bundle.js\" --timeout 120 && npm run start-watcher",
"start-watcher": "npm-watch"

错误是这样的：

[1] resolve failed for "pn": Error: Cannot find module 'pn'
[1] resolve failed for "npm-watch": Error: Cannot find module 'npm-watch'
[1] node_modules/nan
[0] resolve failed for "pn": Error: Cannot find module 'pn'

[1]
[1]   error: unknown option `--config'
[1]
[0]
[0]   error: unknown option `--colors'
[0]
[1] npm run hot:client exited with code 1
--> Sending SIGTERM to other processes..
[0] npm run watch-build-server exited with code 1
[2] npm run dev:server:wait exited with code null

知道出了什么问题吗？

我通过迁移到v2并从那里更新到v3

npm install -g webpack-cli webpack-cli migrate [FILE_PATH].js

Webpack迁移（1.13 - > 3.5）
