我正在使用 gundb 开发电子应用程序。在完成其他所有工作后，我做了一个npm install --save gun. 它完成了这个警告：

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

当我尝试：

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

我得到了一个很长的错误列表，因为我不能犯。他们开始于：

.../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。fsevent 是 gun npm 的依赖项吗？

更新
为了尽可能多地删除其他变量，我将我的 package.json 文件缩减为只有电子......消除了 webpack 和其他依赖项可能存在的问题。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 }

那是一个枪支错误，枪支团队今天早上纠正了它。在纠正错误并在项目中更新 gun 后，我仍然遇到与 webpack 捆绑的问题：

我必须将以下内容添加到我的 webpack.config.js 才能将 gun 与 webpack 一起使用：

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

....

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

....

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

那时一切正常，即使我在 bash 中仍然有以下错误：

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

现在，在浏览器中你应该：

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

解决您的问题。或者使用一个脚本标签，它可以全局导出 Gun。

将来，我们将尝试使用 require('gun') 自动检测环境，而不是自动包含仅 NodeJS 的代码（例如fs，websockets，http 等）
