Question

我在package.json中有以下代码：

"scripts": {
        "start": "concurrently --kill-others \"npm run _server:run\" \"ng serve --aot --progress=false --proxy-config proxy.conf.json\"",
        "lint:client": "ng lint",
        "lint:server": "tslint './server/**/*.ts' -c ./server/tslint.json --fix",
        "test:client": "ng test",
        "e2e:client": "ng e2e",
        "build": "ng build --prod --sm=false --aot --output-path=dist/client && npm run _server:build",
        "_server:run": "tsc -p ./server && concurrently \"tsc -w -p ./server\" \"nodemon --debug dist/server/bin/www.js\" ",
        "_server:build": "tsc -p ./server",
        "postinstall": "npm run build"
    },

如果我跑：

npm run _server：run

一切正常，但如果我跑：

npm run start

我收到以下错误：

我的窗户是葡萄牙语，所以有些部分是葡萄牙语，但实际上它说np程序无法识别。

我对nodejs很新，我认为是'同时'的事情，但我无法弄清楚是什么问题

Answer 1

唯一适合我的方法是添加-原始，因此我使用

concurrently --raw "npm:task1" "npm:task2"

我不知道为什么它只能在这种组合下工作。这当然是npm的功能，因为我尝试的其他命令在没有原始标志的情况下也能完美工作。即以下将正常工作：

concurrently "tsc" "node-sass --output-style compressed index.scss ./out/index.css"

Answer 2

您需要同时安装。

该工具是用 Node.js 编写的，但您可以使用它来运行任何命令。

npm install -g concurrently

或者如果你从 npm 脚本中使用它：

npm install concurrently --save

使用

记住用引号将单独的命令括起来：

concurrently "command1 arg" "command2 arg"

否则会尝试同时运行 4 个单独的命令：command1、arg、command2、arg。

在 package.json 中，转义引号：

"start": "concurrently \"command1 arg\" \"command2 arg\""
