Angular 使用 vscode 源映射的 cli 调试不工作

Question

您好，我已经使用 angular-cli 构建了一个应用程序，我正在尝试使用 vs 代码和 chrome 扩展调试器对其进行调试。过了一会儿，我能够让它工作，很好。发生的事情是我可以在我的打字稿中设置一个断点 class 但它被放置在错误的行号上，例如源映射不正确。

调试过程 - 打开终端 ng 服务然后转到调试选项卡并在 vscode

中单击 F5

我有以下内容：我使用 LaunchChrome 配置

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "LaunchChrome",
            "type": "chrome",
            "request": "launch",
            "url": "http://localhost:4200",
            "sourceMaps": true,
            "webRoot": "${workspaceRoot}",
            "diagnosticLogging": true,
            "userDataDir": "${workspaceRoot}/.vscode/chrome",
             "sourceMapPathOverrides": {
            "webpack:///C:*": "c:/*"
        }
        },
        {
            "name": "AttachChrome",
            "type": "chrome",
            "request": "attach",

Answer 1

我已经更新到 angular-cli-beta19-3 和 typescript 2.0.6 并清除了 chrome 中的缓存，现在可以使用了。

更新：现在使用 angular 2.4.1

有趣的是它不适用于

"sourceMapPathOverrides": {
    "webpack:///*": "${webRoot}/*"
}

此处定义https://github.com/Microsoft/vscode-chrome-debug

但它适用于

"sourceMapPathOverrides": {
    "webpack:///C:*": "c:/*"
}

和 linux 正如@carpinchosaurio 所说

"webpack:///*": "/*"

2017 年 2 月 21 日更新：

使用新版本的 angular 和打字稿，不再需要源映射路径覆盖。

"@angular/compiler-cli": "2.4.8",
"@angular/cli": "1.0.0-beta.32.3",
"typescript": "2.1.6"
angular version 2.4.8

工作设置：

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "LaunchChrome",
      "type": "chrome",
      "request": "launch",
      "url": "http://localhost:4200",
      "sourceMaps": true,
      "webRoot": "${workspaceRoot}",
      "userDataDir": "${workspaceRoot}/.vscode/chrome"
    }
  ]
}

Answer 2

对于仍然感兴趣的任何人，这对我有用 -

 {
        "name": "Launch localhost with sourcemaps",
        "type": "chrome",
        "request": "launch",
        "url": "http://localhost:4200",
        "sourceMaps": true,
        "webRoot": "${workspaceRoot}/src",          
        "userDataDir": "${workspaceRoot}/.vscode/chrome",
        "sourceMapPathOverrides": {              
             "webpack:///./~/*": "${workspaceRoot}/node_modules/*",
             "webpack:///./src/*": "${workspaceRoot}/src/*"
        }
        // Uncomment this to get diagnostic logs in the console
        // "diagnosticLogging": true
    }

Answer 3

只是为了更加强调更新后的：目前不需要 sourceMapPathOverrides 属性在您的 launch.json 中。如果您从旧 Angular 更新项目，只需删除属性即可开始调试。
