删除重复包和 yarn install --pure-lockfile 和 yarn install frozen-lockfile 之间的区别

Remove duplicate packages and difference between yarn install --pure-lockfile and yarn install frozen-lockfile

我的package.json(react-native@0.55.4需要react@16.3.1)

  "dependencies": {
    "expo": "^27.0.1",
    "react": "16.3.1",
    "react-native": "~0.55.2",
    "react-navigation": "^2.0.1"
  }

我的 yarn.lock 文件中有重复的包。

 react@16.3.1:
 version "16.3.1"
 resolved "https://registry.yarnpkg.com/react/-/react-16.3.1.tgz#4a2da433d471251c69b6033ada30e2ed1202cfd8"
 dependencies:
   fbjs "^0.8.16"
   loose-envify "^1.1.0"
   object-assign "^4.1.1"
   prop-types "^15.6.0"

react@^16.0.0:
  version "16.3.2"
  resolved "https://registry.yarnpkg.com/react/-/react-16.3.2.tgz#fdc8420398533a1e58872f59091b272ce2f91ea9"
  dependencies:
    fbjs "^0.8.16"
    loose-envify "^1.1.0"
    object-assign "^4.1.1"
    prop-types "^15.6.0"

运行 $ yarn remove react,结果是

 react@^16.0.0:
  version "16.3.2"
  resolved "https://registry.yarnpkg.com/react/-/react-16.3.2.tgz#fdc8420398533a1e58872f59091b272ce2f91ea9"
  dependencies:
    fbjs "^0.8.16"
    loose-envify "^1.1.0"
    object-assign "^4.1.1"
    prop-types "^15.6.0"

如果我再次尝试 运行,我会得到 error This module isn't specified in a manifest.

如何强制 yarn 删除所有 react 版本,以便我可以手动安装我需要的版本?

yarn install 只需添加这两个包。

yarn install --pure-lockfileyarn install --frozen-lockfile 会解决这个问题吗?

所以根据研究 (https://github.com/yarnpkg/yarn/issues/4379)

Frozen-lockfile 因为它只有在您的锁文件需要更改且不一致时才会失败。 纯锁文件你可能有一个接近无用或非常不准确的锁文件,但你仍然不会失败。 Yarn 会简单地使用它愉快地计算的内部分辨率。

最终我解决了重复的包。使用 package.json

中的分辨率

"resolutions": { "react": "16.3.1" }
