Question

我正在尝试构建一个需要gRPC模块的应用程序。从命令提示符运行时，我的应用程序运行正常 - node server.js

但是，运行nwjs会崩溃并抛出下面的错误 -

我尝试了什么 -

1。如果我启用 window.location.href =＆＃39; http://localhost:3000＆＃39;; 然后nwjs windows显示 localhost 此站点无法访问localhost拒绝连接。并且在显示错误后控制台被清除所以我评论了这个行看到错误。（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. 我手动创建了预期目录 - ＆＃34;预期目录：node-webkit-v0.30.5-win32-x64-unknown＆＃34;在grpc模块中，但现在我在开发工具中看到了另一个错误，认为它解决了上述问题。

Uncaught Error: A dynamic link library (DLL) initialization routine failed.

3。我按照here的说明操作，但也没有运气。它引发了另一组错误。

在第三点尝试说明后，我收到此错误

Server.JS

const express = require('express'),
    bodyParser = require('body-parser'),
    socket = require('socket.io'),
    BigTable = require('@google-cloud/bigtable'),
    PubSub = require('@google-cloud/pubsub'),
    passport = require('passport'),
    mongoose = require('mongoose'),
    cookieSession = require('cookie-session'),
    dotenv = require('dotenv').config(),
    config = require('./config/config'),
    gutils = require('./app/gutils'),
    authRoutes = require('./routes/auth-route'),
    passportSetup = require('./app/passport-setup'),
    app = express(),
    server = app.listen(3000),
    io = socket(server);

/*


App code removed 


*/


app.get('/', (req, res) => {
    res.render('login');
});

app.use(express.static('public'));

console.log('Server running on the port 3000 ...');

P.S。如果我在cmd中运行 node server.js 命令然后运行nwjs，它的工作正常。

Answer 1

我的方法会有所不同。首先，您不能将node.js应用程序和nwjs放在相同的文件夹结构中，因为它们安装节点模块的方式不同。

您应该做什么。

按照http://docs.nwjs.io/en/latest/For%20Users/Getting%20Started/

您可以选择最新版本，但请记住使用哪个版本，因为在安装grpc时需要知道该版本。

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

请清楚您在1中所描述的NWJS版本。最新的是0.32.2。并将target_arch设置为x64

现在将代码逐步复制到您的nwjs应用程序中并运行它。 NWJS与node.js应用程序不同。因此，重要的是将node.js代码和NWJS代码分开。

NW.JS无法加载grpc二进制模块
