尝试连接调试器时 Azure Functions 崩溃，导致 nodemon 永久重新加载

Question

尝试了干净的格式并重新安装 nodemon 无济于事，当运行 azure 函数和 tsc -w 没有改变任何东西时我在循环中得到这个（这是一个片段还有更多）：

[nodemon] files triggering change check: dist/api/index.js.map [nodemon] matched rule: **/. [nodemon] changes after filters (before/after): 1/0 [nodemon] files triggering change check: dist/api/index.js [nodemon] matched rule: **/. [nodemon] changes after filters (before/after): 1/1 [nodemon] restarting due to changes... [nodemon] dist/api/index.js

[nodemon] files triggering change check: dist/graphql/es.js.map [nodemon] matched rule: **/. [nodemon] changes after filters (before/after): 1/0 [nodemon] files triggering change check: dist/graphql/es.js [nodemon] matched rule: **/. [nodemon] changes after filters (before/after): 1/1 [nodemon] restarting due to changes... [nodemon] dist/graphql/es.js

[nodemon] files triggering change check: dist/graphql/databaseInit.js.map [nodemon] matched rule: **/. [nodemon] changes after filters (before/after): 1/0 [nodemon] files triggering change check: dist/graphql/databaseInit.js [nodemon] matched rule: **/. [nodemon] changes after filters (before/after): 1/1 [nodemon] restarting due to changes... [nodemon] dist/graphql/databaseInit.js

我正在使用的 VSCode 配置：

{ "name": "Launch Backend", "type": "node", "request": "launch", "cwd": "${workspaceRoot}", "runtimeExecutable": "nodemon", "runtimeArgs": [ "--inspect=5858", "--verbose" ], "restart": true, "port": 5858, "console": "integratedTerminal", "internalConsoleOptions": "neverOpen" },

和package.json：

"scripts": { "build": "tsc", "watch": "tsc -w", "prestart": "npm run build && func extensions install", "start:host": "func start --cors *", "start": "npm run start:host & npm run watch", "build:production": "npm run prestart && npm prune --production", "test": "echo \"No tests yet...\"" },

这不会在训练营中发生，它的行为符合预期，我已禁用这些文件所在文档的云同步。

Geting this when I just run the base command bypassing nodemon:

Answer 1

nodemon 要求您指定要观看的文件，否则它将检查 cwd 中的任何内容。您可以使用 --watch 标志，即 --watch dist/

Answer 2

经过多次调试后，我发现问题与我的 package.json:

有关

"scripts": {
    "watch": "tsc -w",
    "start:host": "func start --cors *",
    "start": "npm run start:host & npm run watch",
  },

看起来& nom 运行 watch 出于某种原因终止了macOS 中的进程。由于 npm 运行 watch 即使在 windows 上也从未真正起作用（总是必须在文件夹中执行单独的 tsc -w 才能重新编译工作）我决定只删除 eit.

如果有人可以解释原因或提出更好的解决方案，我对此持开放态度，因为这是一个非常俗气的解决方案。
