NW.JS 无法加载 grpc 二进制模块

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，我的应用运行良好 - node server.js

但是，运行 nwjs 会崩溃并抛出以下错误 -

什么，我试过了——

1. 如果我启用 window.location.href = 'http://localhost:3000'; 然后 nwjs windows 显示 localhost 这个站点无法访问 localhost 拒绝连接。并且控制台在显示错误后被清除，所以我评论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，但现在我在开发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.

3. 我已按照说明进行操作 here，但也没有运气。它会引发另一组错误。

在第三点尝试说明后，我收到此错误

服务器.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，它工作得非常好。

Answer 1

我的方法会有点不同。首先，您不能将 node.js 应用程序和 nwjs 放在同一个文件夹结构中，因为它们安装节点模块的方式不同。

你应该做什么。

1. 创建一个基本的 NWJS 应用程序，如 http://docs.nwjs.io/en/latest/For%20Users/Getting%20Started/ 中所述

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 安装。

1. 现在你必须安装你想使用的 grpc。

   npm install grpc --build-from-source --runtime=node-webkit --target=0.32.2 --target_arch=x64
   

如 1 所述，请清楚您拥有的 NWJS 版本。最新版本是 0.32.2 并将 target_arch 设置为 x64

1. 现在将代码逐步复制到您的 nwjs 应用程序并运行它。 NWJS 与 node.js 应用程序不同。因此，将 node.js 代码和 NWJS 代码分开很重要。
