我正在构建和运行 Angular 8/Electron 5 桌面应用程序。在我认为正确设置后,运行该应用程序会显示空白屏幕。
使用:
Electron 5.0.2
Angular CLI 8.0.1
节点 10.16.0
macOS Mojave 10.14.5
...
ng new my-app
npm i -D electron
package.json
{
...
"main": "main.js", //<-- ADDED
"scripts": {
"ng": "ng",
"start": "ng serve",
"build": "ng build",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e",
"electron": "ng build --baseHref=./ && electron ." //<-- ADDED
}
...
}
main.js
const { app, BrowserWindow } = require("electron");
const path = require("path");
const url = require("url");
let win;
function createWindow() {
win = new BrowserWindow({ width: 800, height: 600 });
win.loadURL(
url.format({
pathname: path.join(__dirname, `/dist/index.html`), //<-- CHANGED
protocol: "file:",
slashes: true
})
);
win.on("closed", () => {
win = null;
});
}
app.on("ready", createWindow);
app.on("window-all-closed", () => {
if (process.platform !== "darwin") {
app.quit();
}
});
app.on("activate", () => {
if (win === null) {
createWindow();
}
});
我还将 angular.json 中的 outputPath 更改为“dist”
{
...
"outputPath": "dist"
...
}
使用 npm run electron
启动应用程序
当应用程序打开时,我看到一个空白的白色屏幕。检查后,我可以看到 body 和 <app-root>
元素,但我在页面上看到的只是一个空白的白色屏幕。
在做 ng new my-app
时我在 CLI 中尝试了使用和不使用路由启用标志。
在 Electron 安全警告之前,在 Electron 应用程序控制台中获取这些错误:

最佳答案
我通过将 tsconfig.json 中的 target
更改为 es5
让我的 Electron 应用程序工作。
{
"compileOnSave": false,
"compilerOptions": {
"importHelpers": true,
"module": "esnext",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"moduleResolution": "node",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"target": "es5", <-- HERE
"typeRoots": [
"node_modules/@types"
],
"lib": [
"es2017",
"dom"
]
}
}
在此之前,我在更新 Angular 8 后也出现了空白(白色)屏幕。现在看来 Angular 在 es5
和 es2015
中都进行了构建, Electron 不喜欢那样。我想这会在未来得到解决。
2019-10-24 更新:
看起来这是在 electron@7.0.0
中修复的。您可以使用该版本定位 es2015
。使用 @angular/cli@8.3.14
进行测试。
