nodejs npm start error with concurrently

Question

I have the following code in package.json:

"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"
    },

if i run:

npm run _server:run

everything works fine, but if i run:

npm run start

i get the following error:

[0] [1] [0] 'np' n?o ? reconhecido como um comando interno ou externo,
[0] [1] [0] programa operacional ou ficheiro batch.

my windows is in Portuguese so some parts are in Portuguese, but essentially it says np program not recognized .

i'm pretty new to nodejs,i think is something about 'concurrently' but i can't figure out what is the problem

Answer 1

The only thing that worked for me is to add --raw, so I use

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

I don't know why it works only in this combination. And it is certainly a feature of npm, because other command I tried work perfectly without raw flag. I.e. the following will work fine:

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