我正在尝试构建一个需要GRPC模块的应用程序。在命令提示符下运行时，我的应用程序运行得非常好-node server.js
但是，运行nwjs会崩溃并在下面抛出错误-
什么，我试过了-
一。如果我启用window.location.ref='http://localhost:3000'；
然后nwjs windows显示localhost无法访问此站点localhost拒绝连接。并且console在显示错误后被清除，所以我注释了这一行以查看错误。（错误日志如下所示）
Uncaught Error: Failed to load gRPC binary module because it was not installed for the current system
Expected directory: node-webkit-v0.30.5-win32-x64-unknown
Found: [node-v57-win32-x64-unknown]
This problem can often be fixed by running "npm rebuild" on the current system
Original error: Cannot find module 'C:\Users\BLACK\Desktop\NWJS Xperiments\NuOS-OAuth\node_modules\grpc\src\node\extension_binary\node-webkit-v0.30.5-win32-x64-unknown\grpc_node.node'

2.我已经手动创建了预期目录-“预期目录：node-webkit-v0.30.5-win32-x64-unknown”在grpc模块中，但现在我在dev工具中看到另一个错误，认为它已经解决了上述问题。
Uncaught Error: A dynamic link library (DLL) initialization routine failed.

三。我已经按照指示做了，但也没有运气。它又抛出了一组错误。
在尝试了第三点的说明之后，我得到了这个错误

app.use(express.static('public'));
console.log('Server running on the port 3000 ...');
另外，如果我在cmd中运行node server.js命令，然后运行nwjs，它会非常好地工作。
我正在Windows 10 x64上开发
最佳答案
我的方法会有点不同。首先，node.js应用程序和nwjs不能位于同一文件夹结构中，因为它们安装节点模块的方式不同。
你该怎么做。
创建一个基本的nwjs应用程序，如http://docs.nwjs.io/en/latest/For%20Users/Getting%20Started/
您可以选择最新版本，但请记住您拥有的版本，因为您需要知道GRPC的安装。
现在您必须安装要使用的grpc。
npm install grpc --build-from-source --runtime=node-webkit --target=0.32.2 --target_arch=x64
如1所述，请清楚您的NWJS版本。最近一次是0.32.2
并将目标拱设置为x64
现在一步一步地将代码复制到nwjs应用程序并运行它。nwjs与node.js应用程序不同。因此，分离node.js代码和nwjs代码非常重要。
