Webpack，枪，不能解析文件等，枪需要解析模块'fs‘。

Question

我正在用gundb开发一个电子应用程序。在完成其他工作之后，我做了一个npm install --save gun。它在此警告之后完成：

npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.14

当我试图：

require('gun');
var endpoints;
var gun = Gun(endpoints);

我得到了一长串自那以后我无法犯的错误。它们首先是：

.../node_modules/fs doesn't exist
.../node_modules/fs.webpack.js doesn't exist
.../node_modules/fs.web.js doesn't exist
.../node_modules/fs.js doesn't exist
.../node_modules/fs.json doesn't exist

以下问题无法解决：

@ ./~/gun/lib/file.js 14:10-23
@ ./~/gun/lib/wsp.js 61:39-52
@ ./~/ws/lib/WebSocketServer.js 15:10-2
@ ./~/options/lib/options.js 6:9-2
@ ./~/aws-sdk/lib/api_loader.js 1:9-22
@ ./~/aws-sdk/lib/services.js 1:9-22

我在Linux上。是对枪支npm的依赖吗？

更新

为了尽可能地删除其他变量，我将我的package.json文件简化为只存在webpack和其他依赖项可能出现的electron....eliminating问题。我还删除了我的node_modules并做了一个新的npm install & npm install gun。

这揭示了一个更有用的错误：

Uncaught ReferenceError: Gun is not defined                gun.js:1470

其中指出：

if(typeof window !== "undefined"){ Gun.request = request }
if(typeof module !== "undefined" && module.exports){ module.exports.request = request }

那是个枪虫今早枪队纠正了。在错误被纠正，我在我的项目中更新了枪后，我仍然遇到了与webpack捆绑在一起的问题：

为了和webpack一起使用枪，我不得不在我的webpack.config.js中添加以下内容：

var webpack = require('webpack');
module.exports = {
  devtool: "source-map",
  target: "node", 

....

  module: {
    noParse: [/aws-sdk/],

....

 plugins: [
   new webpack.DefinePlugin({ "global.GENTLY": false })
 ]
....

在这一点上，尽管我在bash中仍然有以下错误，但一切都在正常工作：

WARNING in ./~/ws/lib/BufferUtil.js
Module not found: Error: Cannot resolve module 'bufferutil' in /node_modules/ws/lib
 @ ./~/ws/lib/BufferUtil.js 10:19-40

WARNING in ./~/ws/lib/Validation.js
Module not found: Error: Cannot resolve module 'utf-8-validate' in /node_modules/ws/lib
 @ ./~/ws/lib/Validation.js 10:19-44

现在，在浏览器中，您应该：

var Gun = require('gun/gun');

来解决你的问题。或者使用脚本标记，它可以向全局导出Gun。

在未来，我们将尝试并要求(“gun”)自动检测环境，而不是自动-只包含NodeJS代码(如fs、websockets、http等)。
