````如何在项目中保证node/npm包版本相同？

peerDependencies:{
  vue:^2.5.16
}

`package.json``exports``exports`

{
  "exports": "./index.js"
}

2. exports

{
  "exports": {
    ".": "./index.js",
    "./package.json": "./package.json",
    "./conditions": {
      "import": "./conditions.js",
      "require": "./conditions.cjs"
    }
  }
}

{
  "exports": {
    ".": "./index.js",
    "./subpath": "./subpath/index.js"
  }
}

{
  "exports": {
    ".": {
      "import": "./dist/index.mjs",
      "require": "./dist/index.cjs"
    }
  }
}

{
  "exports": {
    ".": "./index.js",
    "./sub/*": "./sub/*.js"
  }
}

{
  "exports": {
    ".": "./index.js",
    "./alias": "./subpath/index.js"
  }
}

{
  "exports": {
    ".": {
      "node": {
