引导程序:未捕获的类型错误:无法读取未定义的属性“fn" [英] Bootstrap: Uncaught TypeError: Cannot read property 'fn' of undefined
问题描述
我正在尝试使用 Bootstrap 制作一个 Electron 应用程序.我收到此错误消息:
I am trying to make an Electron application with Bootstrap. I get this error message:
Uncaught TypeError: Cannot read property 'fn' of undefined
at setTransitionEndSupport (bootstrap.js:122)
at bootstrap.js:199
at bootstrap.js:201
at bootstrap.js:9
at bootstrap.js:10
我在 package.json 中的依赖是:
My dependencies in the package.json are:
"dependencies": {
"bootstrap": "^4.1.2",
"electron": "^2.0.5",
"jquery": "^3.3.1",
"popper.js": "^1.14.3"
}
我的 index.html 文件是:
My index.html file is:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Release Management Report</title>
</head>
<body>
<div class="container">
<h1>Bootstrap Test</h1>
<p>
We are using node
<script>document.write(process.versions.node)</script>, Chrome
<script>document.write(process.versions.chrome)</script>, and Electron
<script>document.write(process.versions.electron)</script>.
</p>
</div>
<script src="node_modules/jquery/dist/jquery.min.js"></script>
<script src="node_modules/popper.js/dist/umd/popper.min.js"></script>
<script src="node_modules/bootstrap/dist/js/bootstrap.js"></script>
</body>
</html>
然后由Electron快速启动的main.js加载html文件:
Then the html file is loaded by the main.js from Electron quick start:
const { app, BrowserWindow } = require('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.loadFile('index.html')
// Open the DevTools.
win.webContents.openDevTools()
// 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 macOS 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 macOS 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()
}
})
我发现的大多数解决方案都告诉我在 Bootstrap 之前导入 jQuery，但这已经是我正在做的事情了.
Most of the solutions I have found tell me to import jQuery before Bootstrap, but that is already what I am doing.
感谢您的帮助！
推荐答案
我找到了解决问题的方法.
我在 index.html 中添加了一个脚本:
I found a way to solve the problem.
I added a script in the index.html:
<script src="scripts/script.js"></script>
这是 script.js 的内容:
and this is the content of script.js:
window.$ = window.jQuery = require('jquery'); // not sure if you need this at all
window.Bootstrap = require('bootstrap');
我们可以从 index.html 中删除这些行以避免重复导入:
and we can remove these lines from index.html to avoid double import:
<script src="node_modules/jquery/dist/jquery.min.js"></script>
<script src="node_modules/popper.js/dist/umd/popper.min.js"></script>
<script src="node_modules/bootstrap/dist/js/bootstrap.js"></script>
