Question

我正在尝试使用lerna + typescript建立一个monorepo，我以这个仓库为起点：https://github.com/Izhaki/mono.ts

我要实现的目标是调试Visual Studio代码中的代码。我已经尝试过像这样添加launch.json的方法：

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Debug",
            "preLaunchTask": "npm: build",
            "program": "${workspaceFolder}/packages/line/src/index.ts",
            "sourceMaps": true,
            "smartStep": true,
            "internalConsoleOptions": "openOnSessionStart",
            "outFiles": [
                "${workspaceFolder}/packages/line/dist/**/*.js"
            ]
        }
    ]
}

我在导入和使用以下内容时遇到了一些错误：

/Users/davidericci/Desktop/mono.ts-master/packages/line/dist/index.js:1
(function (exports, require, module, __filename, __dirname) { import { getDistance } from '@geo/point';
                                                                     ^

SyntaxError: Unexpected token {

因此，我在tsconfig.build.json（位于包装内）内进行了更改：

"target": "es2017",
"module": "commonjs",

和tsconfig.base.json内（始终在包内）：

{
  "compilerOptions": {
    "lib": ["es2015", "es2016", "dom", "es2017", "es6", "es5"],
    "noUnusedLocals": true
  }
}

但是我仍然得到：

internal/modules/cjs/loader.js:605
    throw err;
    ^

Error: Cannot find module '@geo/point'

作为错误，我认为是因为在代码内部（即使在JS代码中），导入仍指向打字稿。我可能在这里错了。

该项目的所有其他设置均为默认设置。

可以和tsconfig-paths一起使用吗？还是只是launch.json中的某些设置？

非常感谢你们

不幸的是，我不得不放弃使用https://github.com/Izhaki/mono.ts

的想法。

使用标准配置文件，我成功地通过lerna进行了调试，甚至使用了无服务器脱机。

这是我的文件：

launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Debug ms-locations",
      "preLaunchTask": "npm: lerna-tsc",
      "program": "${workspaceFolder}/packages/ms-locations/lib/sample.js",
      "cwd": "${workspaceFolder}",
      "outFiles": [
        "${workspaceFolder}/packages/ms-locations/**/*.js"
      ],
      "protocol": "inspector",
    }

tsconfig

{
"compilerOptions": {
    /* Basic Options */
    "target": "es6", /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017','ES2018' or 'ESNEXT'. */
    "module": "commonjs", /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */
    "lib": [
        "es6"
    ], /* Specify library files to be included in the compilation. */
    "declaration": true, /* Generates corresponding '.d.ts' file. */
    "declarationMap": true, /* Generates a sourcemap for each corresponding '.d.ts' file. */
    "sourceMap": true, /* Generates corresponding '.map' file. */
    /* Strict Type-Checking Options */
    "strict": false, /* Enable all strict type-checking options. */
    "noImplicitAny": true, /* Raise error on expressions and declarations with an implied 'any' type. */
    /* Additional Checks */
    "noUnusedLocals": true, /* Report errors on unused locals. */
    "noUnusedParameters": true, /* Report errors on unused parameters. */
    "noImplicitReturns": true, /* Report error when not all code paths in function return a value. */
    "esModuleInterop": true, /* Enables emit interoperability between CommonJS and ES Modules via creation of namespace objects for all imports. Implies 'allowSyntheticDefaultImports'. */
    "incremental": true
},
"exclude": [
    "node_modules",
    "**/*.spec.ts",
    "packages/ms-api/test/*.ts"
]

}

在我的软件包文件夹中，如果您需要使用无服务器这是tsconfig

{
  "extends": "../../tsconfig.json",
  "compilerOptions": {
  "outDir": "./lib",
  "moduleResolution": "node",
  "noUnusedLocals": false,
  "noUnusedParameters": false,
      "allowSyntheticDefaultImports": true,
  "sourceMap": true,
      "target": "es2017",
  "esModuleInterop": true,
      "incremental": false
  },
  "include": [
      "./src"
  ]
}

即使不完全解决这个问题，我也会将其标记为已接受的答案，但这是我的解决方案。

希望可以帮助某人

我似乎使我的工作方式略有不同，避免了lerna（尽管使用Lerna是单源存储）。

这是我的launch.json：

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Test show",
      "type": "node",
      "request": "launch",
      "address": "localhost",
      "protocol": "inspector",
      "cwd": "${workspaceFolder}/services/shows",
      "program": "${workspaceFolder}/node_modules/serverless/bin/serverless",
      "args": [
        "invoke",
        "local",
        "-f",
        "get",
        "-p",
        "./mocks/get-event.json"
      ],
      "outFiles": [
        "${workspaceFolder}/services/shows/.webpack/service/src/get.js"
      ],
      "autoAttachChildProcesses": true
    }
  ]
}

还有我的tsconfig.json：

{
  "compilerOptions": {
    "lib": ["es2017"],
    "moduleResolution": "node",
    "noUnusedLocals": true,
    "strictNullChecks": true,
    "preserveConstEnums": true,
    "declaration": true,
    "forceConsistentCasingInFileNames": true,
    "esModuleInterop": true,
    "noImplicitReturns": true,
    "strict": true,
    "sourceMap": true,
    "target": "es2017",
    "outDir": ".build"
  },
  "exclude": ["node_modules"]
}

希望这对您或其他人有帮助！
