VSCode插件开发，onDidChangeActiveTextEditor和onDidOpenTextDocument不触发问题如何解决？-灵析社区

通过ai问答vscode，实现打开文件后触发和切换标签页触发弹出消息框，根据ai提供的代码编写，但是没有达到期望效果，期望效果是vscode打开文件后，切换标签，弹出消息框，显示设置的内容 初次进行vscode 插件开发尝试，先从实现打开文件后触发和切换标签页触发弹出消息框开始，通过chat的ai问答得知可以通过onDidChangeActiveTextEditor和onDidOpenTextDocument分别做到标签页切换和打开文件后进行触发 。 extension代码如下 // The module 'vscode' contains the VS Code extensibility API // Import the module and reference it with the alias vscode in your code below const vscode = require('vscode'); // This method is called when your extension is activated // Your extension is activated the very first time the command is executed /** * @param {vscode.ExtensionContext} context */ function activate(context) { //切换标签页 let disposable1 = vscode.window.onDidChangeActiveTextEditor((editor) => { if (editor) { vscode.window.showInformationMessage('Tab switched!'); } }); let disposable2 = vscode.workspace.onDidOpenTextDocument((document) => { vscode.window.showInformationMessage('File opened!'); }); context.subscriptions.push(disposable1, disposable2); } // This method is called when your extension is deactivated function deactivate() {} module.exports = { activate, deactivate } package.json文件部分内容 "activationEvents": [ "onDidChangeActiveTextEditor", "onDidOpenTextDocument" ], 运行测试，没有效果，切换标签页和打开文件后没有出现消息框弹出，这个是怎么回事？是哪里没配置对？
