Nodemon 卡在“因更改而重新启动..."并且不会重新启动服务器 [英] Nodemon stuck at "restarting due to changes..." and won't restart the server

问题描述

我有一个非常基本的 nodemon 配置.我正在修复我继承的这个遗留 node 7 项目，并试图让开发过程变得有点痛苦.首先，一个正确的重启和转换过程(因为它是使用 ES6 模块语法构建的).

I have a pretty basic nodemon configuration. I'm fixing this legacy node 7 project that I inherited and trying to make the development process a little bit painful. First thing first, a proper restart-and-transpile process (since it's built using ES6 modules syntax).

这是我的文件夹结构:

- src
  |- index.js
- dist
  |- index.js
- index.js
- nodemon.js

我运行 nodemon 作为 "start:dev": "nodemon index.js"

I run nodemon as "start:dev": "nodemon index.js"

内容如下:

// index.js
if (process.env.NODE_ENV === 'production') {
  require('./dist/index.js');
} else {
  require('babel-register')({});
  require('babel-polyfill');
  require('./src/index.js');
}

这个想法是在运行时转译代码，这样我就不必像以前那样手动停止服务器、重新转译、启动服务器.

The idea is that the code is transpiled on runtime, so that I don't have to stop server, re-transpile, start server manually, as I have been doing before.

最后但并非最不重要的是，nodemon 配置

Last but not least, nodemon config

// nodemon.js
{
  "restartable": "rs",
  "ignore": [
    ".git",
    "node_modules/**/node_modules"
  ],
  "verbose": true,
  "watch": [
    "src"
  ],
  "env": {
    "NODE_ENV": "development"
  },
  "ext": "js json"
}

我从 MERN 获取了这个设置，我认为它应该可以工作.但是，当我进行更改并保存时，它变成了:

I took this setup from MERN, and I think it should work. However, when I made a change and save, it goes:

[nodemon] files triggering change check: src/index.js
[nodemon] matched rule: /Users/me/project/path/src/**/*
[nodemon] changes after filters (before/after): 1/1
[nodemon] restarting due to changes...
[nodemon] src/index.js

(stuck here. it never restarts)

我一直在检查代码，我唯一不熟悉的可能是导致它的原因我能想到的是 child_process.execFileSync() 调用，这将调用java工具；和一个带有 mysql.createPool()(mysql 包)的连接池.

I've been checking the code, and the only thing that I'm unfamiliar with, that maybe be causing it I can think of would be a child_process.execFileSync() call, that will call a java tool; and a connection pool with mysql.createPool() (mysql package).

在 Node 7.5 和 Node 8.9 中都尝试过.知道哪里出了问题吗?

Tried both in Node 7.5 and Node 8.9. Any idea of what could be wrong?

推荐答案

我正在使用 window 10，并且在我不小心删除了 %PATH% 变量后遇到了这个问题.如果是这种情况，请尝试添加这三个路径:

I am using window 10, and I faced this issue after I accidentally removed my %PATH% variable. Try adding these three paths if it is the case:

C:\Windows;C:\Windows\system32;C:\Windows\System32\Wbem;

C:\Windows; C:\Windows\system32; C:\Windows\System32\Wbem;
