npm 安装包两次吗? [英] Does npm install package twice?

问题描述

我运行 npm install 来安装我的依赖项.

I run npm install to install my dependencies.

第一次，一些包安装失败.

At the first time, some package install failed.

我再次运行 npm install.

npm 会重新安装每个依赖项还是只是不安装包?

Will npm reinstall every dependency again or just the package not be installed?

推荐答案

除了第一次运行 npm install 之外，只会安装丢失的包和需要更新的包.

Running npm install apart from the first time installs only the missing packages and those that need update.

根据 stian 的输入，参考 docs.npmjs.com/cli/install#algorithm

As per stian's input, refer docs.npmjs.com/cli/install#algorithm
