javascript - yarn.lock 文件中同一个包的多个版本

问题描述

我在 yarn.lock 中看到一个包的 3 个不同版本，例如：

angular@1.6:
  version "1.6.10"
  resolved "https://registry.yarnpkg.com/angular/-/angular-1.6.10.tgz#eed3080a34d29d0f681ff119b18ce294e3f74826"
  integrity sha512-PCZ5/hVdvPQiYyH0VwsPjrErPHRcITnaXxhksceOXgtJeesKHLA7KDu4X/yvcAi+1zdGgGF+9pDxkJvghXI9Wg==

angular@>=1.4.0, angular@^1.0.8:
  version "1.7.7"
  resolved "https://registry.yarnpkg.com/angular/-/angular-1.7.7.tgz#26bd87693deadcbd5944610a7a0463fc79a18803"
  integrity sha512-MH3JEGd8y/EkNCKJ8EV6Ch0j9X0rZTta/QVIDpBWaIdfh85/e5KO8+ZKgvWIb02MQuiS20pDFmMFlv4ZaLcLWg==

angular@~1.2.0:
  version "1.2.32"
  resolved "https://registry.yarnpkg.com/angular/-/angular-1.2.32.tgz#df52625a5167919931418dda3a9208b9f5fa3db4"
  integrity sha1-31JiWlFnkZkxQY3aOpIIufX6PbQ=

这是否意味着最终的包包含所有这些，否则 webpack 怎么知道要选择哪个版本？社区中处理该问题的最佳做法是什么？我知道--flat选项，但有数千个包，我需要一段时间才能为每个包选择一个。

解决方案

要调查安装了多少次依赖以及哪些软件包依赖于它（递归），请运行yarn why <package-name>：

查看是否可以升级（或降级）某些包，以确保包中的所有依赖项都使用相同版本的 angular。

例如yarn why execa：：

yarn why v1.22.5
[1/4]   Why do we have the module "execa"...?
[2/4]   Initialising dependency graph...
[3/4]   Finding dependency...
[4/4]   Calculating file sizes...
=> Found "execa@4.0.3"
info Has been hoisted to "execa"
info Reasons this module exists

笔记：

  • 有时，开发依赖会导致这种情况。
