为什么用 yarn2
- 没有 node_moduels
- 依赖以压缩包形式存在
  - 占用空间更少
  - 文件数少
- 依赖压缩包不可变
  - 缓存
  - 构建更加快速
  - 能实现离线安装构建
- 访问界限更加严谨
  - 如果没有定义依赖，则 impor 会失败
  - node_moduels 时只要有都能 import
- 构建速度更快
- 支持插件
- 新增 dlx 命令 - 等同于 npm dlx
所有 .yarnrc.yml 中的配置都可以用环境变量
- 例如 YARN_HTTPS_PROXY - 不会使用 HTTPS_PROXY
  - 只支持 HTTP 代理
注意
- 配置 nodeLinker 为 node-modules 可使用以前的方式

FAQ

yarn set version 慢

可以从现有项目拷贝，免安装

酌情考虑是否需要拷贝缓存 - 一般本地有全局缓存，不拷问题不大

PROJ=/other/porject
cp $PROJ/.yarnrc.yml ./
rsync -a --include=releases --include=plugins $PROJ/.yarn/ .yarn/
