我怎样才能解决`错误：无法find绑定文件.`使用`node-ffi`时？

一些细节：

• Mac OSX 10.11.6
• 节点v6.5.0
• npm v3.10.3
• nvm v0.29.0

我最近build立了一个使用ffi与共享C库交互的npm包。 这个软件包完全可以自己完成（使用babel构build）。 我试图将其整合到一个概念validation应用程序中，并遇到了很多 bindings问题。 我正在使用webpack捆绑我的POC应用程序，这就是我遇到这个问题的地方。

这是我的webpack.config.js ：

 /* eslint-disable */ var webpack = require('webpack'); var path = require('path'); var HtmlWebpackPlugin = require('html-webpack-plugin'); var buildPath = path.resolve(__dirname, 'wp-build/'); module.exports = [ { name: 'frontend', entry: './src/frontend/index.js', output: { path: buildPath, filename: 'frontend.bundle.js', }, module: { loaders: [{ test: /\.js/, exclude: /(node_modules|build)/, loader: 'babel-loader', }], }, plugins: [ new HtmlWebpackPlugin(), ], devServer: { contentBase: buildPath, filename: 'frontend.bundle.js', publicPath: '/assets/', port: 8000, stats: { colors: true, }, }, }, { name: 'backend', entry: './src/backend/server.js', output: { path: buildPath, filename: 'backend.bundle.js', }, module: { loaders: [{ test: /\.js/, exclude: /(node_modules|build|\.json|\.md)/, loader: 'babel-loader', }], }, options: { symlinks: true, }, target: 'node', }, ]; 

frontend任务从这个Javascript（ES6）构build一个包：

console.log('This is the frontend calling!!');

简单的权利？

backend任务从这个Javascript（ES6）构build一个包：

 import Stack from 'stack-vod'; const stack = new Stack(); console.log(stack); 

其中stack-vod是我使用ffi软件包。

以下是POC应用程序的package.json文件：

 { "name": "stack-as-package", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "build": "./node_modules/.bin/webpack", "dev": "./node_modules/.bin/webpack-dev-server" }, "author": "Zachary Abresch <[e-mail]>", "license": "MIT", "devDependencies": { "babel-core": "^6.17.0", "babel-eslint": "^7.0.0", "babel-loader": "^6.2.5", "babel-preset-es2015": "^6.16.0", "babel-preset-stage-0": "^6.16.0", "eslint": "^3.7.1", "eslint-config-airbnb": "^12.0.0", "eslint-plugin-import": "^1.16.0", "eslint-plugin-jsx-a11y": "^2.2.3", "eslint-plugin-react": "^6.4.1", "html-webpack-plugin": "^2.22.0", "webpack": "^1.13.2", "webpack-dev-server": "^1.16.2" }, "dependencies": { "stack-vod": "[Private Gitlab Repository]" } } 

以下是复制问题的步骤：

1. npm i
2. npm run build
3. node ./wp-build/backend.bundle.js

第1步工作正常。 保存几个警告，安装npm软件包时不出错。

步骤2显示此输出：

我已经尝试了一些我在SO和GH上find的“修复”，但没有一个能够工作。 任何人都可以告诉我这里发生了什么，可以做些什么来解决这个问题？ 上个星期我一直在抨击我的头脑，还有两个队友花了几天的时间试图弄明白这一点。

顺便说webpack ， webpack是我的团队的一个要求，因为这最终将被用于一个更大的项目使用electron和webpack已经被用来在那里build立。 所以像“不使用networking包”这样的答案不会削减芥末。 🙂

Answer 1

首先，您可能需要一个json和一个md文件加载器，执行npm i -S json-loader和npm i -S file-loader ，然后在webpack.config.js中进行更新

 "loaders": [{ test: /\.js/, exclude: /(node_modules|build)/, loader: 'babel-loader', }, { test: /\.md(\?v=\d+\.\d+\.\d+)?$/, loader: "file" }, { test: /\.json$/, loader: 'json-loader' }] 

如果这不能解决问题，检查binding.node是否存在后，然后回复，然后我会更新我的答案。
