npm package.json 中没有运行脚本

Question

The problem is that when I do npm start OR npm run customScriptCommand npm just not doing anything with the project and quickly just return new line in the terminal.

I've tried removing node and npm from my machine and then do brew installation for node and npm, but it does not fix the problem.

Then I tried removing node and npm from the brew installation and installing it again from nvm, but it also does not fix the problem.

NPM Details

npm -v -> 6.11.3
which npm -> /usr/local/bin/npm

NodeJS Details

node -v -> v12.12.0
which node ->/usr/local/bin/node

Scripts in package.json

"scripts": {
    "start": "node ./bin/www",
    "devstart": "DEBUG=app-name:* nodemon ./bin/www", //I've changed my actual app name to "app-name"
  },

If I do node./bin/www OR DEBUG=app-name:* nodemon./bin/www it will work:

Update

• I've tried on other project that does not have problem on my colleague's machine, with git clone do npm install and tried to run the project, but it still failed

• Even with fresh project which I just did npm init -y it fail,

{
   "name": "test"
   "version": "1.0.0",
   "description": "",
   "main": "index.js",
   "scripts": {
       "test": "echo \"Error: no test specified\" && exit 1"
   },
   "keywords": [],
   "author": "itsme",
   "license": "ISC"
}

Answer 1

npm config set ignore-scripts false would do the trick for you.

The struggle is real my friend, not following random tutorials from now.

Answer 2

Installing npm install --save-dev nodemon and running npm start did the magic for me

Answer 3

hard to tell without seeing the rest of your package.json but most likely when this happens it's because it is malformed somehow and NPM can't parse it.

Answer 4

You can install yarn and it works; just run yarn start . As to what caused the problem I have no idea.
