VS Code 扩展未在扩展开发主机中加载

Question

我通过以下方式生成了一个示例扩展。 https://code.visualstudio.com/api/get-started/your-first-extension

当我从调试视图运行扩展并搜索扩展“Hello World”时。它根本不会出现在命令面板中。

我的包.json

{
  "name": "testextension",
  "displayName": "TestExtension",
  "description": "",
  "version": "0.0.1",
  "engines": {
    "vscode": "^1.76.0"
  },
  "categories": [
    "Other"
  ],
  "activationEvents": [],
  "main": "./out/extension.js",
  "contributes": {
    "commands": [
      {
        "command": "testextension.helloWorld",
        "title": "Hello World"
      }
    ]
  },
  "scripts": {
    "vscode:prepublish": "npm run compile",
    "compile": "tsc -p ./",
    "watch": "tsc -watch -p ./",
    "pretest": "npm run compile && npm run lint",
    "lint": "eslint src --ext ts",
    "test": "node ./out/test/runTest.js"
  },
  "devDependencies": {
    "@types/vscode": "^1.76.0",
    "@types/glob": "^8.1.0",
    "@types/mocha": "^10.0.1",
    "@types/node": "16.x",
    "@typescript-eslint/eslint-plugin": "^5.53.0",
    "@typescript-eslint/parser": "^5.53.0",
    "eslint": "^8.34.0",
    "glob": "^8.1.0",
    "mocha": "^10.2.0",
    "typescript": "^4.9.5",
    "@vscode/test-electron": "^2.2.3"
  }
}

扩展名.ts

// The module 'vscode' contains the VS Code extensibility API
// Import the module and reference it with the alias vscode in your code below
import * as vscode from 'vscode';

// This method is called when your extension is activated
// Your extension is activated the very first time the command is executed
export function activate(context: vscode.ExtensionContext) {

    // Use the console to output diagnostic information (console.log) and errors (console.error)
    // This line of code will only be executed once when your extension is activated
    console.log('Congratulations, your extension "testextension" is now active!');

    // The command has been defined in the package.json file
    // Now provide the implementation of the command with registerCommand
    // The commandId parameter must match the command field in package.json
    let disposable = vscode.commands.registerCommand('testextension.helloWorld', () => {
        // The code you place here will be executed every time your command is executed
        // Display a message box to the user
        vscode.window.showInformationMessage('Hello World from TestExtension!');
    });

    context.subscriptions.push(disposable);
}

// This method is called when your extension is deactivated
export function deactivate() {}

Answer 1

在扩展中，该engines.vscode属性指定运行扩展所需的 VS Code 本身的最低版本。

包.json

"engines": {
    "vscode": "^1.76.0"
}

开发人员设置中没有消息告诉您您自己的版本已过时；扩展程序只是无法加载。

因此请始终使用最新版本的 VC Code 来开发扩展，或者尝试更改 package.json 中所需的版本。

看来使用 yeoman 代码生成器生成的代码与我拥有的 VS 代码版本（1.73）不兼容。

例如，如其他答案中所述，对于 vscode 版本 >= 1.74 不需要明确提及激活事件

我升级了我的 vscode (1.76) 并且它起作用了。
