“未找到并发命令”，但已全局安装

Question

我使用的是macOs，即使通过npm全局并发安装，但在package.json中将其设置为启动脚本并键入npm start时，仍会出现以下错误。

concurrently - kill-others "npm run server" "npm run client"
sh: concurrently - kill-others: command not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! thesis_fullstack@1.0.0 start: `concurrently - kill-others "npm run server" "npm run client"`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the thesis_fullstack@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/mantzaris/.npm/_logs/2020-04-25T22_40_12_897Z-debug.log

我的package.json文件：

{
  "name": "thesis_fullstack",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "client": "cd client && npm start",
    "server": "cd server && npm start",
    "start": "concurrently - kill-others \"npm run server\" \"npm run client\""
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "concurrently": "3.5.1"
  }
}

Answer 1

我真的不知道我做了什么来修复它。首先，我将命令标志"typo“修改为并发的--kill-others your_commands_here。然后我手动卸载了node，并通过Homebrew重新安装(因为我使用的是MacOs)。在此之后，节点和npm将完全不起作用。修复为：https://stackoverflow.com/a/54583099/13212764。我认为在这一点上运行npm start是可行的。

Answer 2

您需要在本地安装依赖项，以便在任何启动脚本中使用它。运行

npm install --save concurrently

要将其本地安装到项目中，请执行以下操作

Answer 3

您的错误与包本身无关，您可以将其全局保存，也可以将其保存在本地(不是-- save -dev)。

您可以在错误日志中找到问题的解决方案

concurrently - kill-others "npm run server" "npm run client"
sh: concurrently - kill-others: command not found

该命令应该是--kill-others或简称为-k，以下是官方文档：https://github.com/kimmobrunfeldt/concurrently

尝试将此作为您的package.json

{
  "name": "thesis_fullstack",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "client": "cd client && npm start",
    "server": "cd server && npm start",
    "start": "concurrently --kill-others \"npm run server\" \"npm run client\""
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "concurrently": "3.5.1"
  }
}

干杯:)
