NW.JS无法加载 grpc 二进制模块



我正在尝试构建一个需要gRPC模块的应用程序。我的应用程序在从命令提示符 -节点服务器运行时运行良好.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 窗口显示本地主机 无法访问此站点 本地主机拒绝连接。 显示错误后控制台被清除，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

2. 我在grpc 模块内手动创建了预期目录 - ">预期目录：node-webkit-v0.30.5-win32-x64-unknown"，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.我按照这里的说明进行操作，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 ...');

附言如果我在cmd中运行节点服务器.js命令，然后运行nwjs，它工作得很好。

我正在 Windows 10 x64 上开发

我的方法会有点不同。首先，您不能将节点.js应用程序和 nwj 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。

你应该做什么。

  1. 按照 http://docs.nwjs.io/en/latest/For%20Users/Getting%20Started/中所述创建基本的 NWJS 应用程序

您可以选择最新版本，但请记住您拥有哪个版本，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

请明确您拥有的 NWJS 版本，如 1 中所述。最近的一个是 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 与节点.js应用程序不同。因此，将节点.js代码和 NWJS 代码分开非常重要。
