我正在尝试将mongoDB集成到我的nodejs-react应用程序中。我使用猫鼬作为orm。
它始于以下错误
WARNING in ./~/mongoose/~/mongodb/~/mongodb-core/~/bson/~/bson-ext/ext/index.js
Module not found: Error: Cannot resolve 'file' or 'directory' ./win32/x64/bson in /Users/Johannes/Documents/Development/holmes/node_modules/mongoose/node_modules/mongodb/node_modules/mongodb-core/node_modules/bson/node_modules/bson-ext/ext
@ ./~/mongoose/~/mongodb/~/mongodb-core/~/bson/~/bson-ext/ext/index.js 6:10-37
我在stackoverflow上遇到了类似的问题，并在我的webpack配置文件中进行了必要的更改
添加了节点和json加载器。
{test：/.json $ /，loader：＆＃39; json-loader＆＃39; }，
{ 测试：/。node $ /， loader：＆＃39; node-loader＆＃39; }
添加了解析和节点对象。
解决：{
扩展程序：[＆＃39;＆＃39;，＆＃39; .js＆＃39;，＆＃39; .json＆＃39;，＆＃39; .jsx＆＃39;，＆＃39;。 es6＆＃39;，＆＃39; .babel＆＃39;，＆＃39; .node＆＃39;]，
modulesDirectories：[＆＃39; node_modules＆＃39;，＆＃39; app＆＃39; ] }，
节点：{
console：true，
fs：＆＃39;空＆＃39;，
net：＆＃39;空＆＃39;，
tls：＆＃39;空＆＃39; }，
npm install json-loader npm install node-loader
这是我的webpack配置文件现在的样子。

}
所有错误都消失了，但我仍然收到以下警告，并且没有生成包。
