node.js - npm安装时--save-dev如何让保存在package.json中的semver以~开头，而不是^开头 ?

Question

比如我执行了 npm install --save-dev del 后，package.json里自动在devDependencies添加了一条依赖，但是我不希望他是以 ^开头，我希望他默认是以~开头。这个需要什么特殊设置吗

{
  "name": "xxx",
  "version": "0.1.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "xxxx",
  "license": "MIT",
  "devDependencies": {
    "del": "^1.1.1"
  }
}

希望执行完安装命令后是这样的结果

{
  "name": "xxx",
  "version": "0.1.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "xxxx",
  "license": "MIT",
  "devDependencies": {
    "del": "~1.1.1"
  }
}

Answer 1

首先明确这两个的区别：

• ~version "Approximately equivalent to version" See semver(7)
• ^version "Compatible with version" See semver(7)

然后可能有用到的命令行：

• npm install
• npm install [@/]@
