npm ci

安装一个干净的项目

概要

npm ci

示例

确保你有一个包锁和一个最新的安装：

$ cd ./my/npm/project
$ npm install
added 154 packages in 10s
$ ls | grep package-lock

在该项目中运行 npm ci

$ npm ci
added 154 packages in 5s

将 Travis 配置为使用 npm ci 而不是 npm install 构建：

# .travis.yml
install:
- npm ci
# keep the npm cache around to speed up installs
cache:
  directories:
  - "$HOME/.npm"

描述

此命令与 npm install 类似，不同之处在于它旨在用于自动化环境，例如测试平台、持续集成和部署——或任何您希望确保对依赖项进行全新安装的情况。通过跳过某些面向用户的功能，它可以比常规的 npm 安装快得多。它也比常规安装更严格，可以帮助捕获大多数 npm 用户增量安装的本地环境导致的错误或不一致。
