出错现象

npm init -y初始化之后，安装项目npm i prettier -D报错

PS E:\professer\StyleLint\Prettier> npm i prettier -D       
npm ERR! code ENOSELF

出错原因

两次都出现这个错误，其实和prettier包没有关系，是因为package.json的项目名称和安装的依赖同名导致

{
  "name": "prettier",
  "version": "0.1.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "license": "MIT",
  "devDependencies": {},
  "keywords": []
}

解决方案

修改package.json中的name为prettier-sample，总之不要和安装的包名相同即可。
