yarn 命令

常用示例

说明

Yarn is a fast, reliable, and secure dependency manager for JavaScript. It caches every package it downloads, enabling offline installation of previously fetched packages. Yarn parallelizes operations for faster performance compared to npm. Running yarn with no command executes yarn install. Running yarn script executes a user-defined script from package.json. The lockfile yarn.lock ensures consistent installations across machines. Yarn 2+ (Berry) introduces Plug'n'Play for zero-install workflows and improved workspace support. Configuration can be set globally or per-project via .yarnrc.yml.
