`npm install` doesn't install anything?

➜  eslinta git:(master) ✗ npm install eslint --save-dev

  npm WARN eslinta@1.0.0 No repository field.
  ➜  eslinta git:(master) ✗ eslint -v
  zsh: command not found: eslint
  ➜  eslinta git:(master) ✗

What's the reason of this problem? I installed node by nvm.

Answer 1

Command line modules are installed in a project at ./node_modules/.bin so you can run eslint directly with ./node_modules/.bin/eslint . The better approach is to create a script entry in your package.json:

"scripts": {
  "lint": "eslint"
}

because running commands from the scripts entry in package.json will automatically add ./node_modules/.bin to the path. This way you can run your lint with npm run lint

您是否尝试过在全球范围内安装eslint？

npm install -G eslint eslinta@1.0.0
