无法使用带有 angular2 和 angular-cli 的电子定位供应商文件
Unable to locate vendor files using electron with angular2 and angular-cli
我使用 angular-cli 创建了一个示例英雄应用程序(快速入门中的应用程序),它按预期工作。
npm start
开发了我的应用程序,按预期工作。
然而,在 electron 中启动应用程序似乎失败得很惨。对于我的生活似乎无法弄清楚为什么电子无法找到 dist/
.
中包含的文件夹
即我的 dist/
目录有以下内容:
但是,当我启动 electron dist/
(其中包含 index.js
电子主文件)时,控制台输出以下内容:
Failed to load resource: net::ERR_FILE_NOT_FOUND
file:///vendor/systemjs/dist/system.src.js Failed to load resource:
但显然它们在 vendor/
目录中,因为我的 npm start
工作正常。
我的 index.js
几乎是入门的副本:
const electron = require('electron');
// Module to control application life.
const {app} = electron;
// Module to create native browser window.
const {BrowserWindow} = electron;
// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win;
function createWindow() {
// Create the browser window.
win = new BrowserWindow({width: 800, height: 600});
// and load the index.html of the app.
win.loadURL(`file://${__dirname}/index.html`);
// Emitted when the window is closed.
win.on('closed', () => {
// Dereference the window object, usually you would store windows
// in an array if your app supports multi windows, this is the time
// when you should delete the corresponding element.
win = null;
});
}
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow);
// Quit when all windows are closed.
app.on('window-all-closed', () => {
// On OS X it is common for applications and their menu bar
// to stay active until the user quits explicitly with Cmd + Q
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
// On OS X it's common to re-create a window in the app when the
// dock icon is clicked and there are no other windows open.
if (win === null) {
createWindow();
}
});
// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.
为了让您的应用程序使用 file:// 协议,您需要执行以下操作:
在src/index.html里面,将下面这行改成:
发件人:
<base href="/">
到
<base href="./">
希望对您有所帮助。
编辑:此外,忘记提及:如果您的应用程序同时处于在线和离线状态 运行,您可能希望使用某种检测,以便在应用程序 运行 在普通浏览器 window 中,通过 HTTP。
使用最新的 angular-cli 版本,您需要将基本 href 路径作为参数传递给 ng build 命令,而不是在 index.html 文件中更改它:
ng build --base-href .
希望对您有所帮助。
