javascript - Webpack:./~/sqlite3/~/node-pre-gyp/lib/node-pre-gyp.js 中的错误未找到模块:错误:无法解析 'file' 或 'directory' ../package

Question

我想在我的项目中使用 Webpack，但是当我运行

npm run dev

，我收到这个错误。

这是我的 WEBPACK.CONFIG.js

var path = require ('path');

module.exports = {
  entry: './server.js',
  output: {
    filename: 'bundle.js'
  },
  module: {
    loaders:[
      { test: /\.css$/, loader: "style!css" },
      { test: /\.js$/, loader: 'jsx-loader?harmony' },
      { test: /\.json$/, loader: 'json-loader' }
    ]
  },
  resolve: {
    fallback: path.join(__dirname, "node_modules"),
    extensions : ['', '.js', '.jsx']
  },
  resolveLoader: { fallback: path.join(__dirname, "node_modules") },
  target: 'node'
};

这是 package.json。

谁能帮我解决这个问题？

Answer 1

我在 lzma-native 上遇到了类似的问题，它也使用了 node-pre-gyp。问题是它们都直接需要模块中的 node-pre-gyp。我尝试替换使用 node-pre-gyp 的代码行

var nodePreGyp = require('node-pre-gyp');
var path = require('path');
var binding_path = nodePreGyp.find(path.resolve(path.join(__dirname,'./package.json')));
var native = require(binding_path);

进入

var native = require('pre-gyp-find')('lzma_native');
// notice that the parameter here is the binary module name in package.json of lzma-native

这最终对我有用。但是，此解决方案需要我们修改源代码，并添加额外的依赖项“pre-gyp-find”。也许您可以就此向作者发送 PR。

这不是最好的解决方案，因为它实际上并没有解决问题，而是避免了问题。
