同一个包在 dependencies 和 peerDependencies 中的版本不一致

[sillydaddy]

  "node_modules/react-sortable-tree": {
      "version": "2.8.0",
      "resolved": "https://registry.npmjs.org/react-sortable-tree/-/react-sortable-tree-2.8.0.tgz",
      "integrity": "sha512-gTjwxRNt7z0FC76KeNTnGqx1qUSlV3N78mMPRushBpSUXzZYhiFNsWHUIruyPnaAbw4SA7LgpItV7VieAuwDpw==",
      "dev": true,
      "dependencies": {
        "frontend-collective-react-dnd-scrollzone": "^1.0.2",
        "lodash.isequal": "^4.5.0",
        "prop-types": "^15.6.1",
        "react-dnd": "^11.1.3",
        "react-dnd-html5-backend": "^11.1.3",
        "react-lifecycles-compat": "^3.0.4",
        "react-virtualized": "^9.21.2"
      },
      "peerDependencies": {
        "react": "^16.3.0",
        "react-dnd": "^7.3.0",
        "react-dom": "^16.3.0"
      }
    }

dependencies 里面是
"react-dnd": "^11.1.3",

peerDependencies 里面是
"react-dnd": "^7.3.0",

什么原因会导致这种情况呢？

npm install 时，会报错，说^7.3.0 找不到，因为已经有了^11.*.*的版本。这让我只能用 --legacy-peer-deps 来避免这个 react-dnd 包的版本问题。

因为这货自己的 package.json 就已经是这样的了

npm 升级 v7 以后自动 install peer deps，很多老项目懒得更新 peer deps （因为 v4-v6 只有 warning ）的就会出这个毛病。
