npm5 相当于 yarn 的 --pure-lockfile 标志? [英] npm5 equivalent to yarn's --pure-lockfile flag?

问题描述

我正在寻找纱线的等效项 --pure-lockfile 标志.

I'm looking for an equivalent for yarn's --pure-lockfile flag.

这个标志在 CI 中安装依赖项时很有用，当你希望它读取你的锁文件但不修改它时.

This flag is useful when installing dependencies in CI, when you want it to read your lockfile but not modify it.

npm v5 有等价的吗?

Does npm v5 have an equivalent?

推荐答案

npm 5.7 引入了 npm ci 子命令:

npm 5.7 introduced the npm ci subcommand:

使用 npm install 和 npm ci 的主要区别是:

the main differences between using npm install and npm ci are:

• 项目必须有一个现有的package-lock.json或npm-shrinkwrap.json.
• 如果包锁中的依赖项与 package.json 中的依赖项不匹配，npm ci 将退出并报错，而不是更新包锁.
• npm ci 一次只能安装整个项目:无法使用此命令添加单个依赖项.
• 如果 node_modules 已经存在，它将在 npm ci 开始安装之前自动删除.
• 它永远不会写入 package.json 或任何包锁:安装基本上是冻结的.

• The project must have an existing package-lock.json or npm-shrinkwrap.json.
• If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock.
• npm ci can only install entire projects at a time: individual dependencies cannot be added with this command.
• If a node_modules is already present, it will be automatically removed before npm ci begins its install.
• It will never write to package.json or any of the package-locks: installs are essentially frozen.
